Question

I did a program that used two cpp files and one header file and i have done all of it but the 5 step of the assignment ask:

5. Test the performance of your class by performing the following tasks in your program in the given order: A) declare object 1 with no parameters. B) Declare object 2 with valid parameters for the length (7.1) and width (3.2). C) declare object 3 with only a length (6.3) parameter. D) Declare object 4 with invalid parameters for length and width. E) Declare object 5 and initilaize it by assigning object 2 F) Display the length, width, perimeter, and area of all 5 objects and indicate whether or not they are squares. G) Change the length of object 1 to 5.4 and the width to 10.5. H) Change the length of object 4 to 15.6 and the width to 15.6 I) Display the length, width, perimeter, and of all 5 objects and indicate whether or not they are squares.

Here is my code of the Cpp file with steps A-F:

    #include <iostream>
    #include <iomanip>
    #include <cmath>
    #include "rectangle.h"
    using namespace std;
    int main()
    {
        Rectangle objectOne;
        Rectangle objectTwo(7.1, 3.2);
        Rectangle objectThree(6.3);
        Rectangle objectFour(200,300);
        Rectangle objectFive = objectTwo;

        cout << "The first objects information is ";
        objectOne.printInfo();

        cout << "The second objects information is ";
        objectTwo.printInfo();

        cout << "The third objects information is ";
        objectThree.printInfo();

        cout << "The fourth objects information is ";
        objectFour.printInfo();

        cout << "The fifth objects information is ";
        objectFive.printInfo();

    }

My question is how i do steps G and H am i suppose to just change what i declared them as at the top there or do something else?

here is the header file:

    #ifndef Rectangle_H
    #define Rectangle_H
    class Rectangle
    {
    public:
        Rectangle();
        Rectangle(double length);
        Rectangle(double length, double width);
        ~Rectangle();
        void setLengthAndWidth(double, double);
        void setLength(double Length);
        void setWidth(double Width);
        double calculatePerimeter();
        double calculateArea();
        bool isSquare();
        void printInfo();
        double getLength();
        double getWidth();
    private:
        double length;
        double width;
   
    };
    #endif

Explanation / Answer

Dear, #include #include #include #include "rectangle.h" using namespace std; int main() { Rectangle objectOne; Rectangle objectTwo(7.1, 3.2); Rectangle objectThree(6.3); Rectangle objectFour(200,300); Rectangle objectFive = objectTwo; cout
