Write a program to check Armstrong Number or not.

About:
A positive integer is called an Armstrong number (of order n) if
abcd...=an+bn+cn+dn+.....
In the case of an Armstrong number of 3 digits, the sum of cubes of each digit is equal to the number itself. For example, 153 is an Armstrong number because
153=1*1*1+5*5*5+3*3*3

Program:

#include<stdio.h>

void main()

{

int a,n,s=0,l;

printf("Enter any three-digit no:");

scanf("%d",&n);

int b=n;

while(n){

a=n%10;

s=s+(a*a*a);

n=n/10;

}

if(b==s)

printf("Given number is Armstrong");

else

printf("Not Armstrong number");

}
