Armstrong number program in C - Programmer's Mind

Armstrong Number:

An n-digit Number is said to Armstrong number if sum of the nth powers of individual digits of that number is equal to that same number.

 void armstrong(num) {
  int sum = 0, temp = num, noOfDigits = 0;
  while (temp > 0) {
    noOfDigits++;
    temp /= 10;
  }
  temp = num;
  while (temp > 0) {
    sum += pow(temp % 10, noOfDigits);
    temp /= 10;
  }
  if (sum == num) {
    printf("\n%d is an armstrong Number", num);
  } else {
    printf("\n%d is Not an Armstrong Number", num);
  }
}

Output:

Try this program with various inputs and find the numbers which are Armstrong.
Some of the Armstrong numbers are 153,371,1634.............
