Problem Statement - 02C

Write the definition of a class RING in C++ with following description:
Private Members
- RingNumber   // data member of integer type
- Radius       // data member of float type
- Area         // data member of float type
- CalcArea()   // Member function to calculate and assign
               // Area as 3.14 * Radius*Radius
Public Members
- GetArea()    // A function to allow user to enter values of
               // RingNumber and Radius. Also, this
               // function should call CalcArea() to calculate
               // Area
- ShowArea()   // A function to display RingNumber, Radius
               // and Area

Solution

TC++ #6027

 

class RING
{
  int RingNumber ;
  float Radius ;
  float Area ;
  void CalcArea(){Area=3.14*Radius*Radius;}
public:
  void GetArea();
  void ShowArea();
};
void RING::GetArea()
  {
  cin>>RingNumber>>Radius;
  CalcArea();
  }
  void RING::ShowArea()
{
  cout<<RingNumber<<” ”<<Radius<<” ”<<Area<<endl;
}
