Program to find GCD of two numbers using functions.

#include <stdio.h>

int gcd(int u, int v)
{	if (v == 0) return u;
	else return gcd (v, u % v);
}

main()
{  int x, y;

   printf("Input two integers:\n");

   scanf("%d%d",&x,&y);

   printf("The gcd of %d and %d is %d\n",x,y,gcd(x,y));
   return 0;
