C program to calculate power of a number (x^y)

#include <stdio.h>
int power(int,int);
main()
{
int x,y,c;
printf("Enter the value of x\n");
scanf("%d",&x);
printf("Enter the value of y\n");
scanf("%d",&y);
c=power(x,y);
printf("The result is %d\n",c);
}
int power(int x,int y)
{
if(y==0)
return 1;
else
return(power(x,y-1)*x);

}
