The simple example of CLASS in C++, To find the area of the rectangle:

Program Code:

#include <iostream>
using namespace std;
class Rectangle
{
  int l,b,c,area;
  public:
  void getData()
  {
    cout<<"Enter- the Length of the rectangle";
    cin>>l;
    cout<<"Enter the breath of the rectangle";
    cin>>b;
  }
  
  void arearec()
  {
    area=l*b;
  }
  
  void displayData()
  {
    cout<<"Area of the given Rectangle is "<<area;
  }
};
  
  int main()
  {
    Rectangle obj;
    obj.getData();
    obj.arearec();
    obj.displayData();
  }

The output of the program is tested on www.jdoodle.com

Output:

Enter- the Length of the rectangle 5
Enter the breath of the rectangle 7
Area of the given Rectangle is 35
