Answer:
Here is the C++ program:
#include<iostream> //to use input output functions
#include<cmath> //to use math functions
using namespace std; //to identify objects cin cout
double InflationRate(float oldCPI,float newCPI); //function prototype
int main() { //start of main function
float oldCPI,newCPI,rate; //declares two float variables for the old and consumer price indices
char choice; //stores user choice to continue
double sum=0.0; // computes the sum of inflation rates
int count = 0; //to count the number of inflation rates computed
double average = 0.0; //to compute the average inflation rate
do { //this loop continues to execute and ask user to enter cpis
cout << "Enter the old and new consumer price indices: "; //prompts user to enter new and old cpi
cin>>oldCPI>>newCPI; // Read in two float values for the cpi
rate = InflationRate(oldCPI,newCPI); //call the function InflationRate with the two cpis
cout << "Inflation rate is: "<< rate<< endl; //displays the result
sum = sum + rate; //computes sum of inflation rates
count++; //counts number of computed inflation rates
cout<<"Try again? (Y or y): "; //prompts if user wants to continue
cin>>choice; //reads choice of user y or Y
}while((choice=='Y')||(choice=='y')); //the loop continues to repeat as long as user enters small or capital y
average = sum/count; //computes the average inflation rate
cout<<"Average rate is: "<<average;} //displays the average inflation rate
double InflationRate(float oldCPI,float newCPI){ // function that takes two arguments oldCPI and new CPI and computes the inflation rate
return (newCPI - oldCPI) / oldCPI * 100;} //formula to compute inflation rate
Explanation:
1.
/*This program computes the inflation rate using two consumer price indexes. It takes as parameters, the previous price index and current price index and computes inflation rate by the formula:
(newCPI- oldCPI) / oldCPI and multiply the result by 100 */
#include <iostream> //to use input output functions
using namespace std; //to identify objects cin cout
2.
float oldCPI, newCPI; //declare two float variables for old and new consumer price index
cout << "Enter the old and new consumer price indices: "; //prompts user to enter values for old and new cpi
cin>>oldCPI>>newCPI; //read in two float values for the cpi and store them in the variables oldCPI and newCPI
double result = InflationRate(oldCPI,newCPI); //call the function InflationRate with the two cpis
cout << "Inflation rate is: " << result<< endl; //prints the result
3. and 4.
The complete program is given in the Answer section
For example if user enters 238.343 as old cpi and 238.250 as new cpi then the program works as follows:
oldCPI =238.343
newCPI = 238.250
Now the function InflationRate is called by passing these two parameter and this function returns :
return (newCPI - oldCPI) / oldCPI * 100;}
this becomes
(newCPI - oldCPI) / oldCPI * 100
(238.250 - 238.343) / 238.343 * 100
-0.093/238.343 * 100
- 0.00039 * 100
= -0.039 0204
Hence
result = -0.039 0204
Next, sum = sum + rate; statement computes the sum as:
sum = 0.0 + (-0.039 0204)
sum = -0.039 0204
count++ increases the count by 1
count = 1
Next user is asked if he/she wants to continues. If user presses y or Y then user is asked again to enter values for new and old cpi. Suppose user enters the following values:
oldCPI =238.250
newCPI = 237.852
Now the function InflationRate is called by passing these two parameter and this function returns :
return (237.852- 238.250) / 238.250* 100;}
this becomes
(newCPI - oldCPI) / oldCPI * 100
(237.852- 238.250) / 238.250* 100
−0.398/238.250* 100
- 0.001670491 * 100
= -0.167049
Hence
result = -0.167049
Next, sum = sum + rate; statement computes the sum as:
sum = -0.039 0204 + (-0.167049)
sum = -0.206069
count++ increases the count by 1
count = 2
Now lets say the user enters n or any other key when asked if user wants to continue. So the loop breaks and program moves to the statement:
average = sum/count;
This becomes:
average = -0.206069/2
average = −0.103034
Hence
Average rate is: −0.103034

Write an application that accepts up to 20 Strings, or fewer if the user enters the terminating value ZZZ. Store each String in one of two lists—one list for short Strings that are 10 characters or fewer and another list for long Strings that are 11 characters or more. After data entry is complete, prompt the user to enter which type of String to display, and then output the correct list. For this exercise, you can assume that if the user does not request the list of short strings, the user wants the list of long strings. If a requested list has no Strings, output The list is empty. Prompt the user continuously until a sentinel value, ZZZ, is entered.
Answer:
count = 20
i = 0
short_strings = []
long_strings = []
while(i<count):
s = input("Enter a string: ")
if s == "ZZZ":
break
if len(s) <= 10:
short_strings.append(s)
elif len(s) >= 11:
long_strings.append(s)
i += 1
choice = input("Enter the type of list to display [short/long] ")
if choice == "short":
if len(short_strings) == 0:
print("The list is empty.")
else:
print(short_strings)
else:
if len(long_strings) == 0:
print("The list is empty.")
else:
print(long_strings)
Explanation:
*The code is in Python.
Initialize the count, i, short_strings, and long_strings
Create a while loop that iterates 20 times.
Inside the loop:
Ask the user to enter a string. If the string is "ZZZ", stop the loop. If the length of the string is smaller than or equal to 10, add it to the short_strings. If the length of the string is greater than or equal to 11, add it to the long_strings. Increment the value of i by 1.
When the loop is done:
Ask the user to enter the list type to display.
If the user enters "short", print the short list. Otherwise, print the long_strings. Also, if the length of the chosen string is equal to 0, print that the list is empty.
Write a program that will input the names, ages and weights of three siblings and display the lightest followed by the youngest of the siblings. Do the above assignment without using an array of objects. Implementation Create a project asSibling. In the above project, create a class Sibling not containing the main method. In the above project, create a class TestSibling containing the main method.
Answer:
Here is the JAVA program:
Sibling.java class:
import java.util.Scanner; //to accept input from user
public class Sibling { //class name
//private data members of class
private String name; // String type variable to hold the name of sibling
private int age; // int type variable to hold the age of sibling
private int weight; // int type variable to hold the weight of sibling
public Sibling() {} //constructor of class Sibling
public Sibling (String n, int a, int w) { //parameterized constructor
name = n; // refers to name field
age = a; // refers to age field
weight = w; } // refers to weight field
public String getName () { //accessor method to get the current name of sibling
return name; } //returns the name field of the sibling
public int getAge () { //accessor method to get the current age of sibling
return age; } //returns the age field of the sibling
public int getWeight (){ //accessor method to get the current weight of sibling
return weight; } //returns the weight field of the sibling
public void getInput() { //to take input name,age and weight from user
Scanner input = new Scanner(System.in); //Scanner class object
System.out.print("Enter the name: "); //prompts user to enter the name of sibling
name = input.nextLine(); //scans and reads the input name from user
System.out.print("Enter the age: "); //prompts user to enter the age of sibling
age = input.nextInt(); //scans and reads the age from user
System.out.print("Enter the weight: "); //prompts user to enter the weight of sibling
weight = input.nextInt(); } } //scans and reads the input weight from user
Explanation:
Here is the TestSibling class that contains main method:
public class TestSibling { //class name
public static void main (String[] args) { //main method
String name; // to hold name of sibling
int age, weight; // to hold age and weight of sibling
Sibling sib1, sib2, sib3; // objects of Sibling class
sib1 = new Sibling (); // creates object of class Sibling for sibling 1 and calls constructor
sib1.getInput(); // calls getInput method using sib1 object to get the name, age and weight of sibling 1
sib2 = new Sibling (); // creates object of class Sibling for sibling 2 and calls constructor
sib2.getInput(); //calls getInput method using sib2 object to get the name, age and weight of sibling 2
sib3 = new Sibling (); //creates object of class Sibling for sibling 3 and calls constructor
sib3.getInput(); //calls getInput method using sib3 object to get the name, age and weight of sibling 3
Sibling youngest=null, lightest=null; //holds the youngest age and lightest weight of siblings
if (sib1.getAge( )<= sib2.getAge( ) && sib1.getAge( ) <= sib3.getAge( ) ) /*if condition checks if age of sibling 1 is less than or equals to that of sibling 2 and sibling 3, using object of each sibling and getAge method to access age. the logical operator && AND is used so that if condition evaluates to true if sib1 is younger than both sib2 and sib3 */
{ youngest=sib1;} //if the above condition is true then sets sib1 as youngest
else if (sib2.getAge( ) <= sib1.getAge( ) && sib2.getAge( ) <= sib3.getAge( ) ) // else if condition checks if age of sibling 2 is less than or equals to that of sibling 1 and sibling 3
{youngest=sib2;} // if above condition is true then sets sib2 as the youngest
else //if none of the above condition is true then this means that the third has the lowest age
{ youngest=sib3; } //sets sib3 as the youngest
if (sib1.getWeight( ) <= sib2.getWeight( ) && sib1.getWeight( ) <= sib3.getWeight( ) ) //if condition checks if weight of sibling 1 is less than or equals to that of sibling 2 and sibling 3, using object of each sibling and getAge method to access weight of each sibling
{ lightest=sib1; } //if the above condition is true then sets sib1 as having the lightest weight
else if (sib2.getWeight( ) <= sib1.getWeight( ) && sib2.getWeight( ) <= sib3.getWeight( ) ) // else if condition checks if weight of sibling 2 is less than or equals to that of sibling 1 and sibling 3
{lightest=sib2; } //if the above condition is true then sets sib2 as the lightest
else //if none of the above condition is true then this means that the third has the lightest weight
{ lightest=sib3; } //sets sib3 as the lightest
System.out.println("The lightest sibling: " + lightest.getName() +" " + lightest.getAge()+" "+ lightest.getWeight()); } } //calls the getName() getAge() and getWeight() method using object lightest to print the lightest of the siblings
System.out.println("The youngest sibling: " + youngest.getName() +" " + youngest.getAge()+" "+ youngest.getWeight()); //calls the getName() getAge() and getWeight() method using object youngest to print the youngest of the siblings

An employee is paid at a rate of $16.78 per hour for the first 40 hours worked in a week. Any hours over that are paid at the overtime rate of oneand-one-half times that. From the worker’s gross pay, 6% is withheld for Social Security tax, 14% is withheld for federal income tax, 5% is withheld for state income tax, and $10 per week is withheld for union dues. If the worker has three or more dependents, then an additional $35 is withheld to cover the extra cost of health insurance beyond what the employer pays. Write a program that will read in the number of hours worked in a week and the number of dependents as input and will then output the worker’s gross pay, each withholding amount, and the net take-home pay for the week. For a harder version, write your program so that it allows the calculation to be repeated as often as the user wishes. If this is a class exercise, ask your instructor whether you should do this harder version.
Answer:
Here is the C++ program:
#include<iostream> // to use input output functions
using namespace std; //to access objects cin cout
int main() { //start of main function
int hrsWorked; //stores the number of hours worked
int dependents; //stores the number of dependents
double grossPay; //stores the gross pay
char choice; //store the value for choice of user to continue
do { //loop that keeps repeating as often as the user wishes
cout<<"Enter number of hours worked in a week: "; // prompts user to enter number of weeks
cin>>hrsWorked; //reads input value for number of hours worked
cout<<"Enter number of dependents : "; // prompts user to enter number of dependents
cin>>dependents; //reads input value for number of dependents
if(hrsWorked>40) //if hours worked are more than 40
{grossPay = ((40 * 16.78) + (hrsWorked-40)*(16.78*1.5)); } //employee is paid at the overtime rate of one and-one-half times
else //if hours worked are not more than 40
{ grossPay = (hrsWorked*16.78);} // employee is paid at a rate of $16.78 per hour
double ssTax = 0.06* grossPay ; //computes 6% Social Security tax withheld from gross pay
double fIncomeTax = 0.14* grossPay; //computes 14% federal income tax withheld from gross pay
double sIncomeTax = 0.05 * grossPay; //computes 5% state income tax withheld from gross pay
cout<<"worker’s pay: "<<grossPay<<endl; //displays workers pay
cout<<"worker’s gross pay after withholding amounts:"<<endl; //displays workers pay including withholding amounts
cout<<"withhold amount for state income tax is: "<<sIncomeTax<<endl; //displays grosspay with state income tax withheld
cout<<"withhold amount for social security tax is: "<<ssTax<<endl; //displays grosspay with Social Security tax withheld
cout<<"withhold amount for federal income tax is: "<<fIncomeTax<<endl; //displays grosspay with federeal income tax withheld
cout<<"withhold amount for union dues is: $10 "<<endl; // $10 per week is withheld for union dues
if(dependents >= 3) { //if worker has three or more dependents
cout<<"withhold amount of $35 for health insurance "<<endl;
grossPay = grossPay - 35; } //an additional $35 is withheld to cover the extra cost of health insurance beyond what the employer pays
cout<<endl; //prints a new line
double take_homepay; //stores the net take-home pay for the week.
take_homepay = ((grossPay- ssTax- sIncomeTax - fIncomeTax) - 10); //compute the net t ake-home pay for the week
cout<<"net amount take-home pay for the week is: "<<take_homepay; //displays the net take-home pay for the week
cout<<endl; //prints a new line
cout<<"\nDo you want to continue? (press y to repeat or any key to quit)"; //ask user to repeat the calculation
cin>>choice; //reads choice from user
cout<<endl; //prints a new line
}while(choice =='y' || choice =='Y'); } //loop continues to execute till user wants to repeat calculations and stops when user presses any key other than y or Y
Explanation:
The program works as follows:
Suppose number of working hours is 40 and number of dependents is 2
hrsWorked = 40
dependents = 2
if(hrsWorked>40) this condition evaluates to false because hrsWorked is equal to 40 so else part executes:
grossPay = (hrsWorked*16.78); this becomes:
grossPay = 40 * 16.78
grossPay = 671.2
double ssTax = 0.06* grossPay ; this statement withholds 6% Social Security tax from gross pay. This becomes:
ssTax = 0.06* 671.2;
ssTax = 40.272
double fIncomeTax = 0.14* grossPay; this statement withholds 14% federal income tax from gross pay. This becomes:
fIncomeTax = 0.14* 671.2;
fIncomeTax = 93.968
double sIncomeTax = 0.05 * grossPay; this statement withholds 5% state income tax from gross pay. This becomes:
sIncomeTax = 0.05 * 671.2
sIncomeTax = 33.56
if(dependents >= 3) this condition is false because number of dependents is 2
Next to compute net take-home pay the program control moves to the statement:
take_homepay = ((grossPay- ssTax- sIncomeTax - fIncomeTax) - 10)
this becomes:
take_homepay = ((671.2 - 40.272 - 33.56 - 93.968) - 10)
Note that the 10 here is the $10 per week which is withheld for union dues.
take_homepay = ((671.2 - 40.272 - 33.56 - 93.968) - 10)
take_homepay = 503.4 - 10
take_homepay = 493.4

(The Location class) Design a class named Location for locating a maximal value and its location in a two-dimensional array. The class contains public data fields row, column, and maxValue that store the maximal value and its indices in a two dimensional array with row and column as int type and maxValue as double type.Write the following method that returns the location of the largest element in a two-dimensional array.public static int[] locateLargest(double[][] a)The return value is a one-dimensional array that contains two elements. These two elements indicate the row and column indices of the largest element in the two dimensional array. Write a test program that prompts the user to enter a two-dimensional array and displays the location of the largest element in the array. Here is a sample run:Enter the number of rows and columns of the array: 3 4Enter the array:23.5 35 2 104.5 3 45 3.535 44 5.5 9.6The location of the largest element is at (1, 2)
Answer:
Here is the Location class:
public class Location { //class name
public int row; // public data field to hold the value of no. of rows
public int column; // public data field to hold the value of no. of columns
public double maxValue; //public data field to hold the maximum value
public Location(int row, int column, double maxValue) { //parameterized constructor of Location class
//this keyword is used to refer to a current instance variable and used to avoid naming conflicts between attributes and parameters with the same name
this.row = row;
this.column = column;
this.maxValue = maxValue; }
public static Location locateLargest(double[][] a) { //method that takes a 2 dimensional array a as argument and returns the location of the largest element
int row = 0; //initializes row to 0
int column = 0; //initializes column to 0
double maxValue = a[row][column]; //stores largest element
for (int i = 0; i < a.length; i++) { //iterates through rows of a[] array
for (int j = 0; j < a[i].length; j++) { //iterates through columns of array
if (maxValue < a[i][j]) { //if the maxValue is less than the element of 2 dimensional array at ith row and jth column
maxValue = a[i][j]; //then set that element to maxValue
row = i; // i is set to traverse through rows
column = j; } } } // i is set to move through columns
return new Location(row,column,maxValue); } } //calls constructor of class by passing row, column and maxValue as argument
Explanation:
Here is the Main class with a main() function to test program
import java.util.Scanner; //to accept input from user
public class Main { //class name
public static void main(String[] args) { //start of main function
Scanner scan = new Scanner(System.in); //creates Scanner class object to scan the input from user
System.out.print("Enter the number of rows and columns in the array: "); //prompt for user
int row = scan.nextInt(); // reads value of row from user
int column = scan.nextInt(); //reads input value of column
double[][] array = new double[row][column]; //declares a 2 dimensional array named array
System.out.println("Enter the array:"); //prompts to enter array elements
for (int i = 0; i < array.length; i++) { //iterates through the rows of array until the size of array is reaced
for (int j = 0; j < array[i].length; j++) { //iterates through the columns of array
array[i][j] = scan.nextDouble(); } } //reads each element at i-th row and j-th column
Location location = Location.locateLargest(array); //calls locateLargest method by passing array to it in order to locate the largest element in the array
System.out.println("The largest element in a two-dimensional array is: " + location.maxValue); //displays the largest element of array
System.out.println("The location of the largest element is at (" + location.row + ", " + location.column + ")"); } } //displays the location of the largest element in the two dimensional array
Suppose the user enters 2 rows and 2 columns. The elements are:
1 5.5
4.5 3
The program works as follows:
for (int i = 0; i < array.length; i++) this outer loop iterates through rows
i = 0
inner loop for (int j = 0; j < array[i].length; j++) iterates through columns
array[i][j] = scan.nextDouble(); reads the element at position i-th row and j-th column. This becomes:
array[0][0] = scan.nextDouble();
so element at 0th row and 0th column is 1
Location location = Location.locateLargest(array); now this calls the method which works as follows:
double maxValue = a[row][column]; this becomes:
double maxValue = a[0][0];
so maxValue = 1
for (int i = 0; i < a.length; i++) this loop in method iterates through rows and for (int j = 0; j < a[i].length; j++) this iterates through columns of array
if (maxValue < a[i][j]) this becomes:
if (maxValue < a[0][0])
As we know that maxValue = 1 so this if condition is true.
maxValue = a[i][j]; this becomes:
maxValue = a[0][0];
maxValue = 1
Now set row = 0 and column = 0
Now the inner loop value of j is incremented to 1. So j = 1
At next iteration array[0][1] is checked. The element at this position is 5.5
if (maxValue < a[i][j]) is true because 1<5.5 so now value of maxValue becomes:
maxValue = 5.5
and
i = 0 j = 1
This way at each iteration of inner loop the columns are traversed and at each iteration of outer loop rows are traversed.
At next iteration element at array[1][0] is checked which is 4.5. This is not greater than maxValue so maxValue remains 5.5
At next iteration element at array[1][1] is checked which is 3. This is not greater than maxValue so maxValue remains 5.5 .
After both the loops end the statement:
return new Location(row,column,maxValue);
returns row , column and maxValue
where row = 0 column = 1 and maxValue = 5.5
So the output is:
The largest element in a two-dimensional array is: 5.5
The location of the largest element is at (0,1)

Write a function named replaceSubstring. The function should accept three string object arguments entered by the user. We want to look at the first string, and every time we say the second string, we want to replace it with the third. For example, suppose the three arguments have the following values: 1: "the dog jumped over the fence" 2: "the" 3: "that" With these three arguments, the function would return a string object with the value "that dog jumped over that fence". Demonstrate the function in a complete program. That means you have to write the main that uses this.
Answer:
public class Main{
public static void main(String[] args) {
System.out.println(replaceSubstring("the dog jumped over the fence", "the", "that"));
}
public static String replaceSubstring(String s1, String s2, String s3){
return s1.replace(s2, s3);
}
}
Explanation:
*The code is in Java.
Create function called replaceSubstring that takes three parameters s1, s2, and s3
Use the replace function to replace the s2 with s3 in s1, then return the new string
In the main:
Call the replaceSubstring function with the given strings and print the result

Which of the following could NOT be represented by a boolean variable?
Whether a moving elevator is moving up or down
Whether a traffic light is green, yellow or red
Whether a store is open or closed
Whether a light-bulb is on or off
Answer:
Whether a traffic light is green, yellow or red
Explanation:
Boolean variables are variables that can either take one out of two options at any given instance.
Analyzing the given options
1. Elevator:
Possible Directions = Up or Down; That's two possible values
But it can only move in one direction at a given instance.
This can be represented using Boolean
2. Traffic Light:
Possible Lights = Green, Yellow or Red
That's three options.
This can be represented using Boolean
The last two options can be represented using Boolean because they have just two possible values
Hence, option (B) answers the question
Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (current_price * 0.051) / 12.
Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print('{:.2f}'.format(your_value))
Ex: If the input is:
200000
210000
the output is:
This house is $200000. The change is $-10000 since last month.
The estimated monthly mortgage is $850.00.
Note: Getting the precise spacing, punctuation, and newlines exactly right is a key point of this assignment. Such precision is an important part of programming.
main.py
current_price = int(input())
last_months_price = int(input())
''' Type your code here. '''
Answer:
current_price = int(input())
last_months_price = int(input())
change = current_price - last_months_price
mortgage = (current_price * 0.051) / 12
print('This house is $' + str(current_price) + '. The change is $' + str(change) + ' since last month.')
print('The estimated monthly mortgage is ${:.2f}.'.format(mortgage))
Explanation:
Ask the user to enter the current price and last month's price
Calculate the change, subtract last month's price from the current price
Calculate the mortgage using the given formula
Print the results in required format
#include using namespace std; int main( ) { const int NUM_ROWS = 2; const int NUM_COLS = 2; int milesTracker[NUM_ROWS][NUM_COLS]; int i = 0; int j = 0; int maxMiles = -99; // Assign with first element in milesTracker before loop int minMiles = -99; // Assign with first element in milesTracker before loop milesTracker[0][0] = -10; milesTracker[0][1] = 20; milesTracker[1][0] = 30; milesTracker[1][1] = 40;
Answer:
#include <iostream>
using namespace std;
int main()
{
const int NUM_ROWS = 2;
const int NUM_COLS = 2;
int milesTracker[NUM_ROWS][NUM_COLS];
int i = 0;
int j = 0;
int maxMiles = -99; // Assign with first element in milesTracker before loop
int minMiles = -99; // Assign with first element in milesTracker before loop
milesTracker[0][0] = -10;
milesTracker[0][1] = 20;
milesTracker[1][0] = 30;
milesTracker[1][1] = 40;
maxMiles = milesTracker[0][0];
minMiles = milesTracker[0][0];
for (i = 0; i < NUM_ROWS; i++){
for (j = 0; j < NUM_COLS; j++){
if (milesTracker[i][j] > maxMiles){
maxMiles = milesTracker[i][j];
}
if (milesTracker[i][j] < minMiles){
minMiles = milesTracker[i][j];
}
}
}
cout << "Min: " << minMiles << endl;
cout << "Max: " << maxMiles << endl;
return 0;
}
Explanation:
It seems you want to find the min and max value in the array. Let me go through what I added to your code.
Set the maxMiles and minMiles as the first element in milesTracker
Create a nested for loop that iterates through the milesTracker. Inside the loop, check if an element is greater than maxMiles, set it as maxMiles. If an element is smaller than minMiles, set it as minMiles.
When the loop is done, print the minMiles and maxMiles

(5 points) Create a user-defined data structure (i.e., struct) called Point that represents a two-dimensional Cartesian coordinate (x, y). The member variables of this struct will be just x and y, which are both floating-point values. (5 points) Define a function called calculateDistance that takes two parameters, each of type Point* (i.e., pointer to Point) and returns the distance between the two given points. As you may recall, the formula for calculating the distance between two points, say p1(x1, y1) and p2(x2, y2) is:
Answer:
Here is the C++ program:
#include<iostream> //to use input output functions
#include <math.h> //to use sqrt and pow function
#include<iomanip> //to use setprecision
using namespace std; //to identify objects cin cout
struct Point { // structure name
float x,y; // member variables
};
float calculateDistance (Point a, Point b) { //function that that takes two parameters of type Point
float distance; //stores the distance between two points
distance=sqrt(pow(a.x-b.x,2)+pow(a.y-b.y,2)); //formula to compute distance between two points
return distance; } //returns the computed distance
int main() { //start of main function
Point p1,p2; //creates objects of Point
cout<<"Enter point 1 coordinates: "<<endl; //prompts user to enter the value for coordinates of first point
cin>>p1.x; //reads input value of x coordinate of point 1 (p1)
cin>>p1.y; //reads y coordinate of point 1 (p1)
cout<<"Enter point 2 coordinates: "<<endl; //prompts user to enter the value for coordinates of second point
cin>>p2.x; //reads input value of x coordinate of point 2 (p2)
cin>>p2.y; //reads y coordinate of point 2 (p2)
cout<<"The distance between two points is "<<fixed<<setprecision(2)<<calculateDistance(p1,p2);} //calls function by passing p1 and p2 to compute the distance between p1 and p2 and display the result (distance) up to 2 decimal places
Explanation:
The program has a structure named Point that represents a two-dimensional Cartesian coordinate (x, y). The member variables of this struct are x and y, which are both floating-point values. A function called calculateDistance takes two parameters, a and b of type Pointer and returns the distance between the two given points using formula:
[tex]\sqrt{(x_{2}-x_{1} )^{2} +(y_{2}-y_{1} )^{2} }[/tex]
It uses pow function to compute the power of 2 and sqrt function to compute the square root.
Then in main() method the program prompts the user to enter coordinates for two points and calls calculateDistance method to compute the distance between two points and display the result up to 2 decimal places using setprecision(2).
The program along with the output is attached in a screenshot.
No Loops, or if statements, or arrays allowed for this program. You will receive a zero if your program contains any loop, if statement, or array. You need a program to maintain information about your stocks. Assume that you have the following stocks:
Stock Name Number of Shares Buying Price Current Price Yearly Fees
Per Share Per Share
IBM 155 $15.33 $13.33 $5.00
ORACLE 375 $11.77 $12.25 $3.50
SUN MICRO 350 $27.55 $35.75 $12.25
LINKSYS 85 $25.35 $23.34 $6.00
CISCO 50 $45.36 $50.86 $1.50
You must use the data from this table for you Program Set 2 submission.
Write a C program that will perform the following tasks:
Task 1: Allow the user to enter in the data for each stock. Stock name, Number of shares, Buy Price, Current Price and Yearly fees.(The user will not enter the $'s.)
Task 2: Calculate the Initial Cost, Current Cost, and Profit for each stock. The formulas to use are: Initial Cost
Answer:
Here is the C program:
#include <stdio.h> //to use input output functions
int main(){ //start of main function
char *stock_name=NULL; //to store stock name (this is used instead of using char type array)
int shares; //to store number of shares
float buy_price; //to store the buy price
float cur_price; //to store the current price
float fees; //to store the fees
double initial_cost; //to store the computed initial cost
double current_cost; //to store the value of computed current cost
double profit; //to store the calculated value of profit
printf("enter stock name "); //prompts to enter stock name
scanf("%m[^\n]",&stock_name); //reads the input stock name
printf("enter number of shares "); //prompts to enter number of shares
scanf("%d", &shares); //reads the input number of shares
printf("enter the buy price, current price and fees "); //prompts to enter buy price, current price and fees values from user
scanf("%f %f %f", &buy_price, &cur_price, &fees); //reads the values of buy price, current price and fees from user
initial_cost = shares * buy_price; //computes initial cost
current_cost = shares *cur_price; //computes current cost
profit = current_cost - initial_cost - fees; //computes profit for each stock
printf("The stock name is: %s\t\n",stock_name); //displays the stock name
printf("The number of shares: \t%d\t\t\n",shares); //displays the number of shares
printf("The buy price is:\t$\t %0.2f\t\n",buy_price); //displays the buy price
printf("The current price is:\t$\t %0.2f\n",cur_price); //displays the current price
printf("The fees are:\t\t$\t %0.2f\n",fees); //displays the fees
printf("The initial cost is:\t$\t %0.2f\n",initial_cost); //displays the computed initial cost
printf("The current cost is:\t$\t %0.2f\n",current_cost); //displays the computed current cost
printf("The profit is:\t\t$\t %0.2f\n",profit);//displays the computed profit for each stock
return 0; }
Explanation:
Lets say the user input IBM, 150, 11.33 13.33 and 5.00 as stock name, number of shares, buy price, current price and fees values.
So,
stock_name = "IBM"
shares = 150
buy_price = 11.33
cur_price = 13.33
fees = 5.00
Now initial cost is computed as:
initial_cost = shares * buy_price;
This becomes:
initial_cost = 150* 11.33
initial_cost = 1699.5
Next current cost is computed as:
current_cost = shares *cur_price;
This becomes:
current_cost = 150*13.33
current_cost = 1999.5
Next the profit is computed as:
profit = current_cost - initial_cost - fees;
This becomes:
profit = 1999.5 - 1699.5 - 5.00
profit = 295
These values are displayed on the output screen up to 2 decimal places. So the output of the entire program is:
The stock name is: IBM The number of shares: 150 The buy price is: $ 11.33 The current price is: $ 13.33 The fees are: $ 5.00 The initial cost is: $ 1699.50 The current cost is: $ 1999.50 The profit is: $ 295.00
The screenshot of the output is attached.
