Write the definition of a class CONTAINER in C++ with the following description.
Private Members
-Radius, Height // float
- Type // int (1 for Cone, 2 for Cylinder)
- Volume // float
- CalVolume() // Member function to calculate
// volume as per the Type
| Type | Formula to calculate Volume |
| 1 | 3.14*Radius*Height |
| 2 | 3.14*Radius*Height/3 |
Public Members
- GetValues () //A function to allow a user to enter of Radius, Height and Type. Also, call function CalVolume() from it.
- ShowAll () // A function to display Radius, Height, Type and Volume of Container

Solution
Class CONTAINER
{
float Radius, Height;
int Type;
float Volume ;
void CalVolume(float Radius, float Height, int n)
{
Volume = (3.14*Radius*Radius*Height)/n;
}
void CalVolume(float Radius, float Height)
{
Volume = 3.14*Radius*Radius*Height;
}
public:
void GetValues( )
{
cout << "Enter Radius";
cin >>Radius;
cout<<"Enter Height";
cin>>Height;
cout<<"Enter Type (1 for cone and 2 for cylinder)";
cin>>Type;
switch(Type)
{
case 1: CalVolume(Radius, Height, 3);
ShowAll();
break;
case 2: CalVolume(Radius, Height);
ShowAll( );
break;
}
}
void ShowAll()
{
cout<< "Radius : "<<Radius;
cout<<"Height :"<< Height;
cout << "Volume : "<<Volume;
}
