Write a C program to check whether a number is Armstrong or Not!!!

 ARMSTRONG NUMBER: The number which is equal to the sum of cubes of each of its digits.

LOGIC BUILDING:

•  Take input from user.
•  Apply an algorithm which separates the digit of number and and add cube of each.
•  Compare it with the original one.
•  If it is same as original print its Armstrong else its not Armstrong.

CODE:

#include<stdio.h>
int main(){

int num,digit,sum=0,original;    //intializing variables.

printf("Enter the Number: ");
scanf("%d",&num);//taking number from user which he wants to check;

original=num;        //preserving original number for comparation 

        while (num!=0)
{
digit=num%10; // %10 will give us last digit of a number
sum=sum+(digit*digit*digit);  //addition of num will be stored with this algorithm

                 num/=10;        // it means num=num/10;

} 
if (original==sum) //comparation going on
printf("\nThe number %d is a Armstrong",sum);
else
printf("\nThe number %d is not a Armstrong",original);
 
getchar();
return 0;
}

Expected Output:
