这道题用这个程序有什么问题吗？求解，一直显示不通过

Question

#include <stdio.h>
int main()
{
    int a,b,c,d,e,f,g;
    int x = 0;
    int y = 1;
        while(scanf("%d %d",&a,&b) != EOF){
        for (c = a,x = 0;c<=b;c++){
            e = c%10;
            f = (c/10)%10;
            g = (c/100)%10;
            //printf("%d/n",g);
            if (e*e*e+f*f*f+g*g*g == c){
                printf("%d ",c);
                x++;
            }
        }
            printf("%c",8);
        
        if(x == 0){
            printf("no");
        }    
            printf("\n");
        }
            
    return 0;
}

供参考：

#include <stdio.h>
int main()
{
    int a, b, c, d, e, f, g;
    int x = 0;
    //int y = 1;
    while (scanf("%d %d", &a, &b) == 2 && a != 0 && b != 0) {//输入0 0 结束输入，或输入非数字结束输入
        if (a < 100 || b >= 1000) continue;
        for (c = a, x = 0; c <= b; c++) {
            e = c % 10;
            f = (c / 10) % 10;
            g = (c / 100) % 10;
            //printf("%d/n",g);
            if (e * e * e + f * f * f + g * g * g == c) {
                printf("%d ", c);
                x++;
            }
        }
        //printf("%c", 8);
        if (x == 0) {
            printf("no\n");
        }else 
            printf("\n");
    }
    return 0;
}
