Answer:
The answer to this question is given below in the explanation section. However, the correct answer is: student should practice netiquette in an online course when they are participating in online discussion board.
Explanation:
It is important for you as a student to recognize that the online classroom is in fact a classroom, and certain behaviors are expected when you communicate with both your peers and your instructors. These guidelines for online behavior and interaction are known as “netiquette”.
So, the correct option of this question is: students should practice netiquette in an online course when they are participating in an online discussion board. Because the discussion board is opened by the instructor/tutor, he constantly looking for student behavior throughout the discussion. so, students should use netiquette practice during the discussion in the online class.
However, other options are not correct because, in these options, there is not the presence of teacher/instructor. And, also noted that netiquette is practiced in online class by the student.

Explanation:
Write a Java program that can compute the interest on the next monthly mortgage payment. The program reads the balance and the annual percentage interest rate from the console.
The interest rate should be entered as a percentage value and not as a floating-point number (e.g.: for an interest rate of 4.25%, the user should enter 4.25, and not 0.0425). The program should check to be sure that the inputs of balance and the interest rate are not negative. The program should then compute and display the interest amount as a floating-point number with 2 digits after the floating point.
Formula: the interest on the next monthly mortgage payment can be computed using the following formula: Interest = balance x (annualInterestRate / 1200)
Answer:
import java.util.Scanner;
public class Main
{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
double balance, rate, interest;
System.out.print("Enter the balance: ");
balance = input.nextDouble();
System.out.print("Enter the annual percentage interest rate [%4.25 must be entered as 4.25]: ");
rate = input.nextDouble();
if(balance < 0 || rate < 0)
System.out.println("The balance and/or interest rate cannot be negative!");
else{
interest = balance * (rate / 1200);
System.out.printf("The interest amount $%.2f", interest);
}
}
}
Explanation:
Ask the user to enter the balance
Ask the user to enter the interest rate as given format
Check the balance and rate. If any negative value is entered, print an error message. Otherwise, calculate the interest using the given formula and print the interest in required format
java Primary U.S. interstate highways are numbered 1-99. Odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go east/west. Auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. Thus, I-405 services I-5, and I-290 services I-90. Given a highway number, indicate whether it is a primary or auxiliary highway. If auxiliary, indicate what primary highway it serves. Also indicate if the (primary) highway runs north/south or east/west. Ex: If the input is: 90 the output is: I-90 is primary, going east/west. Ex: If the input is: 290
Answer:
Here is the JAVA 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 input = new Scanner(System.in); // creates Scanner class object to take and scan input from user
int highwayNum; //to hold value of highway number
int primaryNum; //to hold value of primary number
highwayNum = input.nextInt(); //scans and takes input value of highwayNum from user
if(highwayNum<1 || highwayNum>999) //if highway number is less than 1 or greater than 999
System.out.println(highwayNum+" is not a valid interstate highway number."); //display this message if above if statement is true
else{ //when above if statement is false
if(highwayNum>=1 && highwayNum<=99){ //checks if highway number is greater than equal to 1 and less than equal to 99
System.out.print("I-"+highwayNum+" is primary, going ");
if(highwayNum%2==0) //checks for the even highway number
System.out.println("east/west."); //prints this if highway number is even
else //if highway number is odd
System.out.println("north/south."); } //prints this if highway number is odd
else{ // if auxiliary number
primaryNum = highwayNum%100; //computes primary number
System.out.print("I-"+highwayNum+" is auxillary, serving I-"+primaryNum+", going "); //displays the auxiliary number and which primary number it is serving
if(primaryNum%2==0) //if primary number is even
System.out.println("east/west."); //displays this if primaryNum is even
else //when primaryNum is odd
System.out.println("north/south."); } } }}//displays this if primaryNum is odd
Explanation:
I will explain the program with an example:
Suppose user enters 90 as highway number So
highwayNum = 90
if(highwayNum<1 || highwayNum>999)
This if condition evaluates to false because highwayNum is 90 and its not less than 1 or greater than 999.
So else part executes which has an if statement:
if(highwayNum>=1 && highwayNum<=99)
This statement evaluates to true because highwayNum is 90 so it lies between 1 and 99 inclusive. So the statement inside this if condition executes:
System.out.print("I-"+highwayNum+" is primary, going ");
This statement prints the following message on output screen:
I-90 is primary going
Now next statement if(highwayNum%2==0) checks if highwayNum is completely divisible by 2 and is an even number. This takes the mode of highwayNum by 2 and returns the remainder. 90%2 is 0 because 90 is completely divisible by 2 and hence it is an even number. So this if condition evaluates to true and program control moves to the statement:
System.out.println("east/west."); which prints east/west on the output screen. Hence the output of the entire program is:
I-90 is primary, going east/west.
Screenshot of the program along with its output is attached.

Consider the following method.
public double secret(int x, double y) { return x/2.0; }
Which of the following lines of code, if located in a method in the same class as secret, will compile without
error?
int result = secret(4, 4);
double result = secret(4.0, 4);
int result = secret(4, 4.0);
double result = secret(4.0, 4.0);
double result = secret(4, 4.0);
Answer:
The answer to this question is given below in the explanation section.
Explanation:
Consider the following method.
public double secret(int x, double y)
{
return x/2.0;
}
The return type of this function is double, so where it will store the result in a variable, that variable should be of double type. So, among given options, the correct option is double result = secret(4, 4.0);
All others options are incorrect and will give the error.
for example:
int result = secret(4, 4);
in it, the function secret is accepting first integer and second double parameters, while you are passing all integer variables.
int result = secret(4, 4.0);
you are not allowed to store double value into integer.
double result = secret(4.0, 4.0); in it you are passing incorrect types of parameter.

Write a method called priceIsRight that mimics the guessing rules from the game show The Price is Right. The method accepts as parameters an array of integers representing the contestants’ bids and an integer representing a correct price. The method returns the element in the bids array that is closets in value to the correct price without being larger than that price. For example, is an array called bids stores the value {200, 300, 250, 1, 950, 40} the call of priceIsRight(bids, 280) should return 250, since 250 is the bid closets to 280 without going over 280. If all bids are larger than the correct price, your method should return -1.
Answer:
Here is the method :
public static int priceIsRight(int[] bids, int correctPrice) { /*definition of method priceIsRight that accepts as parameters an array of integers representing the contestants’ bids and an integer representing a correct price */
int nearest = -1; //initializes the closest value to -1
for(int i = 0; i < bids.length; i++) { //iterates through the bids array until length of the bids array reaches
if(bids[i] <= correctPrice && bids[i] > nearest) //checks the element of the bids array that is closest (nearest) in value to the correct price without being larger than that price
nearest = bids[i]; } //sets that element of bids at index i which is closest to correcPrice to nearest variable
return nearest; } //returns the element in the bids array that is nearest in value to the correctPrice
Explanation:
To check the working of the above method you can call this function in main()
public static void main(String[] args) { //start of main function
int[] bids = {200, 300, 250, 1, 950, 40}; //declares and array and assigns elements to it
System.out.println(priceIsRight(bids,280)); } } //calls priceIsRight method by passing the bids array and 280 as correct price
The method works as follows:
Suppose we have an array called bids with elements {200, 300, 250, 1, 950, 40}
nearest = -1
correctPrice = 280
The for loop for(int i = 0; i < bids.length; i++) works as follows:
At first iteration:
i = 0
i< bids.length is true because i=0 and bids.length = 6
so program control moves inside the loop body:
if(bids[i] <= correctPrice && bids[i] > nearest) this if statement becomes:
if(bids[0] <= correctPrice && bids[0] > nearest)
This if condition has two parts and it uses && AND logical operator between them so both of the conditions should hold for the if condition to evaluate to true.
bids[0] <= correctPrice
the element at 0-th index of bids array is 200 and correctPrice= 280 So 200 is less than 280. This part of if condition is true.
bids[0] > nearest
the element at 0-th index of bids array is 200 and nearest = -1. So 200 is greater than -1. Hence this part of if condition is also true.
Hence both the parts of the if statement are true and if condition evaluates to true. So the program control moves to the statement:
nearest = bids[i];
This becomes:
nearest = bids[0]
nearest = 200
At second iteration:
i = 1
i< bids.length is true as i=1 and bids.length = 6
so program control moves inside the loop body:
if(bids[1] <= correctPrice && bids[1] > nearest) this if statement becomes:
if(bids[1] <= correctPrice && bids[1] > nearest)
bids[1] <= correctPrice
the element at 1st index of bids array is 300 and correctPrice= 280 So 300 is greater than 280. This part of if condition is false.
So the if condition evaluates to false. So the value of nearest remains the same.
nearest = 200
At third iteration:
i = 2
i< bids.length is true as i=2 and bids.length = 6
if statement becomes:
if(bids[2] <= correctPrice && bids[2] > nearest)
bids[0] <= correctPrice
the element at 2nd index of bids array is 250 and correctPrice= 280 So 250 is less than 280. This part of if condition is true.
bids[2] > nearest
the element at 2nd index of bids array is 250 and nearest = 200. So 250 is greater than 200. Hence this part of if condition is also true.
Hence if condition evaluates to true. So the program control moves to the statement:
nearest = bids[i];
nearest = bids[2]
nearest = 250
At fourth iteration:
i = 3
i< bids.length is true because i=1 and bids.length = 6
if statement becomes:
if(bids[3] <= correctPrice && bids[1] > nearest)
bids[3] <= correctPrice
the element at third index of bids array is 1 and correctPrice= 280 So 1 is less than 280. This part of if condition is true.
bids[3] > nearest
the element at 3rd index of bids array is 1 and nearest = 250. So 1 is less than 200. Hence this part of if condition is false. So value of nearest remains the same
nearest = 250
At fifth iteration:
i = 4
i< bids.length is true because i=4 and bids.length = 6
if statement becomes:
if(bids[4] <= correctPrice && bids[4] > nearest)
bids[4] <= correctPrice
the element at 4th index of bids array is 950 and correctPrice= 280 So 950 is greater than 280. This part of if condition is false.
So the if condition evaluates to false. Hence
nearest = 250
At sixth iteration:
i = 5
i< bids.length is true because i=5 and bids.length = 6
so program control moves inside the loop body:
if statement becomes:
if(bids[5] <= correctPrice && bids[5] > nearest)
bids[5] <= correctPrice
the element at fifth index of bids array is 40 and correctPrice= 280 So 40 is less than 280. This part of if condition is true.
bids[5] > nearest
the element at 5th index of bids array is 40 and nearest = 250. So 40 is less than 250. Hence this part of if condition is false. So value of nearest remains the same
nearest = 250
Now the loop breaks at i = 6 because i < bids.length condition evaluates to false.
The statement return nearest; executes now. This returns the value of nearest. So this method returns 250.

Consider two different implementations of the same instruction set architecture. The instructions can be divided into four classes according to their CPI (class A, B, C and D). P1 with a clock rate of 3GHz and CPIs of 3, 2, 1, 4, and P2 with a clock rate of 2.5GHz and CPIs of 2, 2, 2, 2.Processor Class A Class B Class C Class DP1 3 2 1 4P2 2 2 2 2Given a program with a dynamic instruction count of 1.0E5 instructions divided into classes as follows: 10% class A, 30% class B, 40% class C, and 20% class D.1. Which implementation is faster?2. What is the global CPI for each implementation?3. Find the clock cycles required in both cases?
Answer:
Follows are the solution to this question:
Explanation:
The architecture of two separate iterations with the same the instruction set can be defined in the attached file please find it.
Calculating the value of total instruction count:
[tex]= 1 \times 10^{5} \\\\= 10^5[/tex]
[tex]\text{P1 clock rate} = 3 \ GHz \\ \\\text{P2 clock rate} = 2.5 \ GHz \\\\\text{Class Division: 10 \% of class A,} \text{30 \% of class B, 40 \% of class C, 20 \% of class D} \\\\[/tex]
In point a:
Calculating P1 device mean CPI:
[tex]Average CPI = \frac{summation \times instruction \ count \times CPI}{total \ instruction \ count}\\[/tex]
[tex]= (10^5 \times 10 \% \times 3 + 10^5 \times 30 \% \times 2 + 10^5 \times 40 \% \times 2 + 10^5 \times 20%[/tex] [tex]\times 4) \times \frac{1} {1 \times 10^5}\\\\[/tex]
[tex]= \frac{(3 \times 10^4 + 6 \times 10^4 + 8 \times 10^4 + 8 \times 10^4)}{1 \times 10^5}\\\\ = \frac{25\times 10^4}{1 \times 10^5}\\\\= 2.5[/tex]
Estimating P2 device Average CPI:
[tex]= (1 \times 10^5 \times 10 \% \times2 + 1 \times 10^5 \times 30 \% \times 2 + 1 \times 10^5 \times 40 \% \times 2 + 1 \times 10^5 \times 20 \%[/tex][tex]\times 2) \times \frac{1}{ 1 \times 10^5}[/tex]
[tex]= \frac{(2 \times 10^4 + 6 \times 10^4 + 8 \times 10^4 + 4 \times 10^4)}{1 \times 10^5} \\\\= \frac{20 \times 10^4}{1 \times 10^5} \\\\= 2 \\[/tex]
[tex]\text{Execution time} = \frac{\text{instruction count} \times \text{average CPI}}{clock rate}}[/tex]
[tex]= \frac{1 \times 10^5 \times 2.5}{3} \ GHz \\\\ = \frac{1 \times 10^5 \times 2.5}{3 \times 10^9} \ sec \ as \ 1 \ GHz \\\\ = 10^9 \ Hz \\\\= 0.083 \ msec \ as \ 1 \ sec \\\\ = 10^3 \ msec[/tex]
Calculating processor execution time P2:
[tex]= \frac{1 \times 10^5 \times 2}{2.5} \ GHz \\\\= \frac{1 \times 10^5 \times 2}{2.5 \times 10^9} \ sec \ as\ 1 \ GHz \ = 10^9 \ Hz \\\\ = 0.080 \ msec \ as \ 1 \ sec \\\\ = 10^3 \ msec[/tex]
Since P2 is less than P1 for processor execution time, P2 is therefore faster than P1.
In point b:
Global processor P1 CPI = 2.5
Global processor P2 CPI = 2
In point c:
Finding Processor P1 clock cycles:
[tex]\text{Clock cycle = instruction count} \times \text{average CPI}[/tex]
[tex]= 1 \times 10^5 \times 2.5 \\\\ = 2.5 \times 10^5 \ cycles[/tex]
Finding Processor P2 clock cycles:
[tex]\text{Clock cycle = instruction count} \times \text{average CPI} \\\\[/tex]
[tex]= 1 \times 10^{5} \times 2\\\\ = 2 \times 10^{5} \ cycles\\\\[/tex]

The term that is not related to the font is font grammar. There is nothing such thing as font grammar. The correct option is a.
What are fonts?Fonts are the shape and design for the different alphabetic. These are present in computers and phones. We can create multiple designs shaped by these fonts.
Web designers could choose a common typeface (like Sans serif) if they want everyone to view the same font because not all machines can display all fonts.
Some designers may opt to use a fancier typeface and then specify a more straightforward font as a "backup" that a computer can use if the fancier font cannot be seen. The theme is a predetermined collection of hues, fonts, and visual effects.
Therefore, the correct option is a, Font grammar.

Suppose that we are working for an online service that provides a bulletin board for its users. We would like to give our users the option of filtering out profanity. Suppose that we consider the words cat, dog, and llama to be profane. Write a program that reads a string from the keyboard and tests whether the string contains one of our profane words. Your program should find words like cAt that differ only in case. Option: As an extra challenge, have your program reject only lines that contain a profane word exactly. For example, Dogmatic concatenation is a small category should not be considered profane.
Answer:
Here is the JAVA program:
import java.util.*; //to use Scanner class, Lists
public class Main{ //name of class
public static void main(String[] args) { //start of main function
String sentence = "CaT and catalog are not same"; //a string
sentence = sentence.toLowerCase(); // converts the words in the sentence to lowercase
Scanner sc = new Scanner(sentence); //creates Scanner class object
List<String> profane_words = profaneList(); // creates a list of profane words i.e. cat, dog and llama
int count = 0; //count the number of profane words
while (sc.hasNext()) { //reads string as tokens and returns true if scanner has another token
String word = sc.next(); //returns the next complete token (word) and store it into word variable
for (String profane : profane_words) { // looks for each profane in profane_words list
if (word.matches(".*\\b" + profane + "\\b.*") && ! sentence.matches(".*" + profane + "[a-z].*\\b" + profane + "\\b.*") && ! sentence.matches(".*[a-z]" + profane + ".*\\b" + profane + "\\b.*")) { //uses matches() method that identifies whether a word in the string matches the given regular expression.
count++; //each time if the word of sentence matches with word given in profane_list then 1 is added to count
System.out.println("The word " + profane + " is a profane!"); //displays the word which is profane
} } }
System.out.println("Number of profane words: "+ count); } //displays the number of profane words found in the sentence
private static List<String> profaneList() { //list of profane words
List<String> profane_words = new ArrayList<>(); //creates an array list of profane words named as profane_words
profane_words.add("dog"); //adds word "dog" to the list of profane words
profane_words.add("cat"); //adds word "cat" to the list of profane words
profane_words.add("llama"); //adds word "llama" to the list of profane words
return profane_words; }} //returns the list of profane words
Explanation:
I will explain the program with an example:
sentence = "CaT and catalog are not same";
First this sentence is converted to lower case as:
sentence = "cat and catalog are not same";
Now the while loop uses hasNext() which keeps returning the next token and that token is stored in word variable.
Next the for loop iterates through the list of profane_words to check each profane word with the word in a sentence.
Next this statement:
if (word.matches(".*\\b" + profane + "\\b.*") && ! sentence.matches(".*" + profane + "[a-z].*\\b" + profane + "\\b.*") && ! sentence.matches(".*[a-z]" + profane + ".*\\b" + profane + "\\b.*"))
uses regular expressions to find the profane words in the sentence. The logical operator&& AND between the three expressions is used so all of the three must hold for the if condition to evaluate to true.
word.matches(".*\\b" + profane + "\\b.*") expression uses \b to check an exact match of the word. \b is meta-character to find a match at the beginning and at the end. So this checks if the word of a sentence matches with the profane in the profane list.
! sentence.matches(".*" + profane + "[a-z].*\\b" + profane + "\\b.*") && ! sentence.matches(".*[a-z]" + profane + ".*\\b" + profane + "\\b.*"))
These two expressions check if profane does not include as a part of another word in the sentence. This solves the extra challenge. Like here in the sentence we have a word catalog which is not a profane but a profane cat is included in this. So this will not be considered as a profane.
Every time a word matches with the profane from profane list, the value of count variable is incremented to 1.
In the end the statement:
System.out.println("Number of profane words: "+ count);
prints the number of profane words in the sentence.
List<String> profane_words = new ArrayList<>(); creates the list of profane words and add() method adds the words to the list profane_words. So profane_words list contain "cat", "dog" and "llama"
Hence the output of this program is:
The word cat is a profane! Number of profane words: 1

Based on the unit content and your own ideas, how would you define a video game in your own words? What separates a regular video game from a “good” video game and explain how immersion is a factor. How would you determine whether a game succeeds or fails in its objectives
Answer:
A video game would be a series of steps to produce or outcome / end in the form of controller a character or the how the game can be played and being able to play it at some level, but a good game would have multiple questions and a hard difficulty maybe even a customizable section for your character or object. In other words a Video game would be a series of steps to produce a outcome from controlling a character and a Good video game would be the same but added a level of difficulty and harder mechanics into the game.
Explanation:

Answer:
To start, the core aspects of a Good game are goals and actions, rules, and challenges, without these the game would not be very good. The challenges of the game should be the perfect balance between too hard and easy so that the player doesn’t rage quit, but also doesn’t quit because there basically is no challenge. A good game should be simple to learn, but hard to master, to keep players playing for a long time. A good game also has a lot of content to allow for countless hours of gameplay. determine whether a game succeeds or fails in its objectives by judging them individually to see if it all makes up a good game.
One of your professors has asked you to write a program to grade her midterm exams, which consist of only 20 multiple-choice questions. Each question has one of four possible answers: A, B, C, or D. Create a file "CorrectAnswers.txt" and write the correct answers for each question on a separate line so that the first line contains the answer to the first question, the second line contains the answer to the second question, and so forth. Similarly, create a file "StudentAnswers.txt" and write the student’s answers for each question on a separate line. Write a program that reads the contents of the CorrectAnswers.txt file into a char array, and then reads the contents of file StudentAnswers.txt into a second char array. The program should determine the number of questions that the student answered correctly and then display the following: • The total number of questions answered correctly. • The percentage of questions answered correctly. • If the percentage of correctly answered questions is 75% or greater, the program should indicate that the student passed the exam. Otherwise, it should indicate that the student failed the exam.
Answer:
Here is the program that determines the number of questions that the student answered correctly.
#include <iostream> //to use input output functions
#include <fstream> // to handle files
#define size 20 //size of questions is fixed to 20
using namespace std; //to identify objects cin cout
int correctAnswers(char answers[], char correct[]); //to count correct answers given by student
int main(){ //start of main function
char correct[size]; // array stores correct answers
char answers[size]; //stores answers of students
int result; //stores the correct answers result of student
double percentage; //stores the percentage of correct answers
int counter; //counts number of correct answers given by student
ifstream reader("CorrectAnswers.txt"); //reads the contents of CorrectAnswers.txt file
if(!reader){ //if file cannot be read/opened
cout<<"Cannot open the file"<<endl; //displays error message
return 0; }
counter = 0; //sets counter to 0 initially
while( (reader>>correct[counter++]) && counter < size ); //reads each answer from CorrectAnswers.txt and stores it in char array correct[] at each iteration of while loop
reader.close(); //closes the file
reader.open("StudentAnswers.txt"); //opens StudentAnswers.txt file
if(!reader){ //if file could not be opened
cout<<"Cannot open file"<<endl; //displays this error message
return 0; }
counter = 0; //sets counter to 0
while( (reader>>answers[counter++]) && counter < size ); //reads each answer from StudentAnswers.txt and stores it in char array answers[] at each iteration of while loop
result = correctAnswers(answers,correct); //calls correctAnswers method to compute the correct answers given by student and stores the result of correct answers in result variable
percentage = 100.0*result/size; //computes percentage of correct answers of student
cout<<"The total number of questions answered correctly: "<<result<<endl; //displays total no of qs answered correctly
cout<<"The percentage of questions answered correctly: "<<percentage<<" %"<<endl; //displays computed percentage
if( percentage >= 75 ){ //if percentage of correctly answered questions is 75% or greater
cout<<"Student has passed the exam!"<<endl; } //displays that the student passed the exam
else { //if percentage of correctly answered questions is below 75%
cout<<"Student has failed the exam!"<<endl; } //displays that the student failed the exam
return 0; }
int correctAnswers(char answers[], char correct[]){ //method to compute the number of correct answers
int countCorrect = 0; //stores the count of correct answers
for(int i=0; i<size; i++){ //iterates 20 times to match answers from both the files of 20 questions
if( answers[i] == correct[i] ){ // if the student answer in StudentAnswers.txt file matches with the correct answer given in CorrectAnswers.txt file
countCorrect++; } } //adds 1 to the countCorrect every time the student answer matches with the correct answer
return countCorrect; } //returns the number of questions that the student answered correctly
Explanation:
The program is well explained in the comments mentioned with each line of code.
Here are the two files that can be used to check the working of the above program. You can create your own text files too.

Also if the number of wrong answers are to be displayed then add this method to the above code:
void wrongAnswers(char answers[], char correct[]){ //method takes two arrays one with correct answers and the other with student answers
for(int i=0; i<size; i++){ //iterates 20 times
if( answers[i] != correct[i] ){ //if the answer by student does not match with correct answer
cout<<"Question Number: "<<i+1<<endl; //the question that is answered incorrectly
cout<<"Correct answer is: "<<correct[i]<<endl; //displays the correct answer
cout<<"Student answer is: "<<answers[i]<<endl; } } } //displays the answer that student gave
Now call this method in main() as:
if(result < size){ //if result is less than size i.e. 20
cout<<"The questions answered incorrectly"<<endl; //number of questions that are answered incorrectly
wrongAnswers(answers,correct); //calls method to compute the wrongly answered questions
}else{ //if result is not less than size
cout<<"No incorrect answers."<<endl; } //no questions incorrectly answered
cout<<"Number of missed questions: "<<size-result<<endl; //displays the number of missed questions
The screenshot of the output is attached.
Which statements are true about conditional statements? Check all that apply. They perform actions or computations. They are based on conditions. They can be executed only when conditions are false. They are also called conditional constructs. They are sometimes called compound statements, They have conditions that must be Boolean (IF, AND, or NOT) in form. DONE
Answer:they perform actions
They are based on conditions
They are also called conditional statements
They have conditions
Explanation:
The statements which are true about conditional statements are as follows:
They perform actions or computations. They are based on conditions.They are also called conditional constructs.They have conditions that must be Boolean (IF, AND, or NOT) in form.Thus, the correct options for this question are A, B, D, and F.
What do you mean by Conditional statements?The Conditional statement may be defined as a type of declaration that can significantly be written in the form “If P then Q,” where P and Q are sentences. For this conditional statement, P is known as the hypothesis while Q is called the conclusion.
According to the context of this question, conditional statements always manufacture actions or computations. They never execute when conditions are false. That's why they are referred to as conditional statements. They also possess conditions based on Boolean (IF, AND, or NOT).
Therefore, the correct options for this question are A, B, D, and F.
