the base class's ________ affects the way its members are inherited by the derived class.
Group of answer choices
A.return data type
B. name
C.construction
D. access specification
E. None of these
The base class's access specification affects the way its members are inherited by the derived class. The correct option is D.
What is access specification?When a class is defined to derive from another class, all of the base class's members—aside from its constructors and finalizers—are automatically added to the derived class.
Without having to reimplement anything, the derived class makes use of the code from the base class. The derived class can have more members added to it. A member function of a base class that can be redefined by a derived class is known as a virtual function.
Therefore, the correct option is the D. access specification.

Using technology, calculate the weighted mean of the rors for each portfolio. Based on the results, which list shows a comparison of the overall performance of the portfolios, from best to worst?.
Option B is the best option. Based on the data, the following list analyzes the total performance of the portfolios, rating them from best to worst:
Portfolios 2, 3, and 1, in that order.
The weighted average ROR is determined by summing the asset return rates and the percentage of the portfolio invested in each investment.
Portfolio No. 1:
$700 + $2575 + $220 + $1000 + $1430 = $5925 Total Investment
As a result, the total investment is $5,925.
Weighted Average ROR= (-3.8% * $700) / $5925 + (2.1% * $2575) / $5925 + (11.3% * $220) / $5925 + (5.8% * $1000) / $5925 + (1.6% * $1430) / $5925 + (5.8% * $1000) / $5925 + (1.6% * $1430) / $5925 + (5.8% * $1000)
WAROR = (-0.0045) + 0.0091 + 0.0042 + 0.0098 + 0.0039 = 0.0225
As a result, the Weighted Average ROR is 2.25%. (third)
Portfolio No. 2:
$1250 + $1700 + $1515 + $1345 + $1,675 = $7485 Total Investment

In the above code, There are a few issues with the provided code. Here are some of them:
The Declare Boolean fatCalories line should be Declare Real fatCalories.The fatCalories variable is not being used in the calculatedSum module. Instead, you are re-calculating the percentage of calories from fat. It would be more efficient to pass the value of fatCalories as an argument to the calculatedSum module, rather than recalculating it.In the calculatedSum module, the Set keyword should be replaced with fatCalories =.The If statement should compare fatCalories to the desired threshold (e.g. 0.3) using a comparison operator such as < or >. Currently, the If statement will always evaluate to false because fatCalories < 0.3 is an assignment statement.The Display statement inside the If block should use proper capitalization (e.g. "This food is low in fat" instead of "this food is low in fat").What is the Coding about?When the code above is revised, the new code will be:

Codehs computer science problem:
We are going to use the Student class that we completed in the last exercise and add a new SchoolClub class. Start by adding your Student class from the last exercise.
After that, add the constructor for the SchoolClub class. For this class, your constructor should take a Student object for the leader and a String club name (in that order). You should also initialize the number of members at zero in the constructor.
Test your code with the StudentTester class. This is the same as the last exercise, so you will need to add a statement to a club and then print it out.
Here is an example of the SchoolClub class implemented with a Student class:
class Student {
private:
string name;
int grade;
public:
Student(string name, int grade) {
this->name = name;
this->grade = grade;
}
string getName() {
return name;
}
int getGrade() {
return grade;
}
};
class SchoolClub {
private:
Student leader;
string clubName;
int numMembers;
public:
SchoolClub(Student leader, string clubName) {
this->leader = leader;
this->clubName = clubName;
this->numMembers = 0;
}
Student getLeader() {
return leader;
}
string getClubName() {
return clubName;
}
int getNumMembers() {
return numMembers;
}
void addMember() {
numMembers++;
}
};
int main() {
Student leader("John", 10);
SchoolClub club(leader, "Chess Club");
club.addMember();
club.addMember();
cout << club.getClubName() << " led by " << club.getLeader().getName() << " has " << club.getNumMembers() << " members." << endl;

}
In this code, the SchoolClub class has a constructor that takes in a Student object for the leader and a string for the club name. It also initializes the number of members to zero. The class also has methods to get the leader of the club, the club name and the number of members. In the main method, the code creates a Student object for the leader and a SchoolClub object with the leader and club name. The club object is then used to add members and get information about the club.
