Question

C++ question. Must use #include <iostream> and "using namespace std;" You must also have only a .cpp and .h file

Define a class called Rectangle that can store the height and width of a rectangle as instance variables, has a constructor that allows you to set the height and width when you create a Rectangle, a default constructor that sets both height and width to 0, and functions to return the following values:

* the perimeter [ which should be 2 * (height + width)]
* the area [which should be height * width]

Answer 1

C++ CODE:

Rectangle.h file code:

class Rectangle{
   int height;
   int width;
public:
   Rectangle(int x=0,int y=0){
       height = x;
       width = y;
   }
   int perimeter(){
       return 2*(height+width);
   }
   int area(){
       return height*width;
   }
};
Main Program CODE:

#include <iostream>
#include "rectangle.h"
using namespace std;

int main() {
   Rectangle rec(5,4);
   cout<<rec.perimeter()<<'\n';
   cout<<rec.area()<<'\n';
   return 0;
}
