C语言求所有的水仙花数,每行输出5个。要求:水仙花数的判断过程用函数实现

#include <stdio.h>
#include <math.h>

// 判断一个数是否为水仙花数
int isNarcissus(int num) {
    int sum = 0;
    int temp = num;
    int digits = 0;
    while (temp != 0) {
        digits++;
        temp /= 10;
    }
    temp = num;
    while (temp != 0) {
        int digit = temp % 10;
        sum += pow(digit, digits);
        temp /= 10;
    }
    return sum == num;
}

int main() {
    int count = 0;
    for (int i = 100; i <= 999; i++) {
        if (isNarcissus(i)) {
            printf("%d ", i);
            count++;
            if (count % 5 == 0) {
                printf("\n");
            }
        }
    }
    return 0;
}
