Printing sum of cubes of a digits of a number.[C Program Code]

This program prints the sum of cubes of a digits of a number.
For eg. If we input 111, we get the output as 3 which equals (1³+1³+1³ = 3).

	#include<stdio.h>
	int main()
	{
	int a,sum = 0 ,copy,n,i;
	printf("Enter the number: ");
	scanf("%d",&a);
	copy = a;
	while(a!=0)
	{
	i=a%10;
	sum = sum + (i*i*i);
	a=a/10;
	}
	printf("The sum of cube of digits of %d is %d",copy,sum);
	getch();
	return(0);
	}
