Write a Program in c++ for function Overloading.

Program:- Find the volume of cylinder, cube and rectangular box.

Coding:- 

                     #include<iostream.h>


float volume(float r, float h)
{
float vol;
vol= 3.14*(r*r)*h;
return vol;

}


float volume(float s)
{
float vol;
vol=s*s*s;
return vol;

}

float volume (float l, float b, float h)

{
float vol;
vol=l*b*h;
return vol;
}


void main()

{
float radius, side , length, breadth, height , vol;
int option;
 do{
cout<<" \n enter 1 for cylinder, 2 for cube, 3 for rectangular box and 4 for exit ";

cin>>option;

switch(option)
{
 case 1 :    cout<<"enter the value of radius and height of cylinder\n";
 cin>>radius>>height;
 vol=volume(radius, height);
 cout<< "volume = "<<vol<<" cubic units \n";
break;

case 2: cout<<"enter the value of side \n";
cin>>side;
vol=volume (side);
cout<<"\n volume  = "<<vol<<" cubic unit";
break;


 case 3: cout<<" enter the value of length, breadth and height ";
cin>>length>>breadth>>height;
vol=volume(length,breadth,height);
cout<<"\n volume  = "<<vol<<" cubic unit";
break;

default:  cout<<"invalid entry ";
break;

}


}  while (option>0 && option< 4);

}

Output:-
