GIVEN NUMBER IS ARMSTRONG NUMBER OR NOT

/* THE GIVEN NUMBER IS ARMSTRONG NUMBER OR NOT */

#include<stdio.h>
#include<conio.h>

void main()
{
    int n,a,sum=0,temp;
    clrscr();
    printf("Enter a number: ");
    scanf("%d",&n);
    temp=n;
    while(n>0)
   {
         a=n%10;
         sum=sum+(a*a*a);
         n=n/10;
    }
    if(sum==temp)
         printf("%d is an Armstrong number",temp);
    else
         printf("%d is not an Armstrong number",temp);
   getch();
}

Sample output:
Enter a number: 153
153 is an Armstrong number

EXAMPLE 1: 153
TOTAL DIGITS IN 153 IS 3
AND 1^3 + 5^3 + 3^3 = 1 + 125 + 27 = 153
