WAP in C++ to print surface area of cylinder.

Here is a program to print surface area of cylinder. This program asks user to input radius and height of Cylinder.
Don’t forget to define “PI” before void main.

#include <iostream.h>
#include <conio.h>
#define pi 3.1415
void main()
{
int a, r, h;
cout<<”Enter the radius & height of the cylinder”<<endl;
cin>>r>>h;

a=2*pi*r*h;
cout<<”The surface area of cylinder is “<<a<<endl;
getch();
}
