Armstrong Numbers in C Program

Armstrong Number :  The Armstrong Numbers is a Number. Such That the Sum ! of it's digits raised to the third power is equal to the number ! itself.

For Example :  Take A Armstrong Number Like 153

1 ³  + 5³    +3³  =  1+ 125 + 27 = 153      //  Here Power of 3 is number of digits in Given number.

Program For Armstrong Number Find in c Program

#include <stdio.h>
 int power(int, int);
 int main()
{
   int n, sum = 0, temp, remainder, digits = 0;
   printf("Enter an integer\n");
   scanf("%d", &n);
   temp = n;
   while (temp != 0) 
{
   digits++;
   temp = temp/10;

}

   temp = n;
   while (temp != 0) {
   remainder = temp%10;
   sum = sum + power(remainder, digits);
   temp = temp/10;
 }

   if (n == sum)
  printf("%d is an Armstrong number.\n", n);
   else
   printf("%d is not an Armstrong number.\n", n);
   return 0;
}

int power(int n, int r) 
{
   int c, p = 1;
   for (c = 1; c <= r; c++) 
   p = p*n;
   return p;   

}
