#include<stdio.h>
int main()
{
    int m,a, b, c;
    m = 100;
    printf("1000以内水仙花数为：\n");
    while (m < 1000)
    {
        a = m / 100;
        b = m / 10 % 10;
        c = m % 10;
        if (m = a * a * a + b * b * b + c * c * c)
            printf("%5d\n", m);
        m = m + 1;
    }
}

Code 2:

#include<stdio.h>
int main()
{
    int m,a, b, c;
    
    printf("1000以内水仙花数为：\n");
    for(m = 100;m < 1000;m = m + 1)
    {
        a = m / 100;
        b = m / 10 % 10;
        c = m % 10;
        if (m = a * a * a + b * b * b + c * c * c)
            printf("%5d\n", m);
        
    }
