C++ programming questions: Consider the following function header for a member f

Question

C++ programming questions:

Consider the following function header for a member function. void Circle:: getRadius() a. What is the name of the function? b. What class does the function belong to? What is a mutator function? Give the interface declaration of an accessor function in class Car, called get Year, which will return the year the car was made (an int). Define the accessor in a way that ensures it does not modify any data members. Assume the Car class interface is stored in file car.h. Give the preprocessor directives to ensure that this file only gets included once in a project.

Explanation / Answer

4) Given member function is:

void Circle::getRadious()

a)In the above member function name of the function is getRadious()
b)It belcongs the class Circle.

A mutator function is nothing but a member function which allows for editing protected data member. Following are the conditions for mutator functions:

1) Parameter should have the value assigned to data member. And it must be same type as the data member.

2) Does not need to return a value.

6)
public: explicit Car()
{
}
explicit Car(int year, std::string make):year_(year),make_(make){ speed_= 0;}
int getYear()
{
return year_;
}
