Question

using c++

E2b:Design a class named Rectangle to represent a rectangle . The class contains:

(1) Two double data members named width and height which specifies the width and height of the rectangle .

(2) A no-arg constructor that creates a rectangle with width 1 and height 1.

(3) A constructor that creates a rectangle with the specified width and height .

(4) A function named getArea() that returns the area of this rectangle .

(5) A function named getPerimeter() that returns the perimeter of this rectangle .

Your solution:

Output:

Answer 1

#include <iostream>
using namespace std;
  
class Rectangle {
private:
double width, heigth;
public:
Rectangle()
{
width = 1;
heigth = 1;
}
Rectangle(double x,double y)
{
width=x;
heigth=y;
}
double * getparameter( ) {
static double r[2];
r[0]=width;
r[1]=heigth;
return r;
}
double getArea()
{
return(width*heigth);
}
  
  
};
int main()
{
double *p,x,y;
cout<<"enter the width and heigth:\n ";
cin>>x>>y;
Rectangle q;
Rectangle p1(x,y);
p=p1.getparameter();
cout<<"parameter of rectangle width and heigth are: "<<*p<<" and "<<*(p+1)<<"\n";
cout<<"Area of rectangel is: "<<p1.getArea();
