Question

Write a program that contains a class Rectangle with two private double precision members iLength and iWidth, public set and get member functions for these two members, a two argument constructor that sets the length and width to any two user specified values and a void function area() that computes the area and then prints this value by inserting it into the cout output stream. Write a main function that ereates a Rectangle with a length of 10 and width of 20 and computes its area

please use c++

Answer 1

#include<iostream>
using namespace std;
class Rectangle
{
//declaring private variables length and breadth
   private:
       double iLength,iWidth;
   public:
   //public methods to get and set length and width of rectangle
   double set_iLength(double l)
   {
   iLength=l;   
   }
   double set_iWidth(double w)
   {
   iWidth=w;   
   }
   double get_iLength()
   {
   return iLength;   
   }
   double set_iWidth()
   {
   return iWidth;   
   }
   //two argument constrctor to set length and width
   Rectangle(double l,double w)
   {
   iLength=l;
   iWidth=w;
   }
   // function to calculate area
       void area()
       {
           cout<<iLength*iWidth;
       }
};
int main()
{
   Rectangle r(10,20);
   r.area();
   return 0;
}
