改正求水仙花数的这段代码#include<stdio.h> int is(int number); int main(void) { int number, m, n; scanf("%d,%d", &m, &n); for (number = m; number <= n; number++) printf("%d\n", is(number)); return 0; } int is(int number) {int x, y, z; x = number % 10; y = number / 10 % 10; z = number / 100; if (x*x*x + y*y*y + z*z*z == number) {result = number; return result;} }

在代码中，函数is没有返回值，应该将int改为void，并将if语句中的return语句改为printf语句输出水仙花数。修改后的代码如下：

#include <stdio.h> 

void is(int number); 

int main(void) { 
    int number, m, n; 
    scanf("%d,%d", &m, &n); 
    for (number = m; number <= n; number++) { 
        is(number); 
    } 
    return 0; 
} 

void is(int number) { 
    int x, y, z; 
    x = number % 10; 
    y = number / 10 % 10; 
    z = number / 100; 
    if (x*x*x + y*y*y + z*z*z == number) { 
        printf("%d\n", number); 
    } 
}
