you create a programmer-defined class and then use it in a C++ program. The program should create two Rectangle objects and find their area and perimeter. Instructions Ensure the class file named Rectangle.cpp is open in your editor. In the Rectangle class, create two private attributes named length and width. Bothlength and width should be data type double. Write public set methods to set the values for length and width. Write public get methods to retrieve the values for length and width. Write a public calculateArea()method and a public calculatePerimeter() method to calculate and return the area of the rectangle and the perimeter of the rectangle. Open the file named MyRectangleClassProgram.cpp. In the MyRectangleClassProgram, create two Rectangle objects named rectangle1 and rectangle2 using the default constructor as you saw in MyEmployeeClassProgram.cpp. Set the length of rectangle1 to 10.0 and the width to 5.0. Set the length of rectangle2 to 7.0 and the width to 3.0. Print the value of rectangle1’s perimeter and area, and then print the value of rectangle2’s perimeter and area.

OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Question
In this lab, you create a programmer-defined class and then use it in a C++ program. The program should create two Rectangle objects and find their area and perimeter.
Instructions
- Ensure the class file named Rectangle.cpp is open in your editor.
- In the Rectangle class, create two private attributes named length and width. Bothlength and width should be data type double.
- Write public set methods to set the values for length and width.
- Write public get methods to retrieve the values for length and width.
- Write a public calculateArea()method and a public calculatePerimeter() method to calculate and return the area of the rectangle and the perimeter of the rectangle.
- Open the file named MyRectangleClassProgram.cpp.
- In the MyRectangleClassProgram, create two Rectangle objects named rectangle1 and rectangle2 using the default constructor as you saw in MyEmployeeClassProgram.cpp.
- Set the length of rectangle1 to 10.0 and the width to 5.0. Set the length of rectangle2 to 7.0 and the width to 3.0.
- Print the value of rectangle1’s perimeter and area, and then print the value of rectangle2’s perimeter and area.
- Execute the program by clicking the Run button at the bottom of the screen
GIVEN CODE
MyRectangleClassProgram.cpp
// This program uses the programmer-defined Rectangle class.
#include "Rectangle.cpp"
#include <iostream>
using namespace std;
int main()
{
Rectangle rectangle1;
Rectangle rectangle2;
rectangle1.setLength(10.0);
rectangle1.setWidth(5.0);
rectangle2.setLength(7.0);
rectangle2.setWidth(3.0);
cout << "Perimeter of rectangle1 is " << rectangle1.calculatePerimeter() << endl;
cout << "Area of rectangle1 is " << rectangle1.calculateArea() << endl;
cout << "Perimeter of rectangle2 is " << rectangle2.calculatePerimeter() << endl;
cout << "Area of rectangle2 is " << rectangle2.calculateArea() << endl;
return 0;
}
Rectangle.cpp
// Rectangle.cpp
using namespace std;
class Rectangle
{
public:
// Declare public methods here
private:
// Create length and width here
};
void Rectangle::setLength(double len)
{
}
void Rectangle::setWidth(double wid)
{
// write setWidth here
}
double Rectangle::getLength()
{
// write getLength here
}
double Rectangle::getWidth()
{
// write getWidth here
}
double Rectangle::calculateArea()
{
// write calculateArea here
}
double Rectangle::calculatePerimeter()
{
// write calculatePerimeter here
}
