C语言练习：检查并打印出输入的两个输入的整数之间的阿姆斯壮（Armstrong）数

阿姆斯壮数(armstrong number) 定义：阿姆斯壮数(armstrongnumber) 是等于其数字的立方数之和的数字，例如：0，1，153，370，371，407等。
现在试着理解为什么153是一个阿姆斯壮数字， 153 = (1*1*1)+(5*5*5)+(3*3*3)。

C语言检查输入数据是不是阿姆斯壮数

#include <math.h>
#include <stdio.h>
int main() {
  int low, high, number, originalNumber, rem, count = 0;
  double result = 0.0;
  printf("Enter two numbers(intervals): ");
  scanf("%d %d", &low, &high);
  printf("Armstrong numbers between %d and %d are: ", low, high);

  // swap numbers if high < low
  if (high < low) {
    high += low;
    low = high - low;
    high -= low;
  }
   
  // iterate number from (low + 1) to (high - 1)
  // In each iteration, check if number is Armstrong
  for (number = low + 1; number < high; ++number) {
    originalNumber = number;

    // number of digits calculation
    while (originalNumber != 0) {
      originalNumber /= 10;
      ++count;
    }

    originalNumber = number;

    // result contains sum of nth power of individual digits
    while (originalNumber != 0) {
      rem = originalNumber % 10;
      result += pow(rem, count);
      originalNumber /= 10;
    }

    // check if number is equal to the sum of nth power of individual digits
    if ((int)result == number) {
      printf("%d ", number);
    }

    // resetting the values
    count = 0;
    result = 0;
  }

  return 0;
}
