}
int volume(int a)
{
return(a*a*a);
}
double volume(int r,double h)
{
return(3.14*r*r*h);
}
double volume(int l,int b,double h1)

OUTPUT:
----------
Volume of Shapes:
**************
Enter the Side of the cube     :5
Enter the radius and height of the cylinder  :2 5 2.5
Enter the length,breadth & height of the rectangle : 10  12  5.6

Volume of cube       : 125
Volume of Cylinder   :66.04899
Volume of rectangle  :672
