水仙花数，但是五位数的时候没有结果输出，不知道为什么，但是三位数和四位数可以判断。

#include<stdio.h>
main()
{
    int a,b,c,d,e,f,g,h;
    while(scanf("%d",&a)!=EOF)
    {

        {
            
        if(a>=100&&a<=999)
        {b=a%10;
        c=a/10%10;
        d=a/100;
        h=d*d*d+b*b*b+c*c*c;
        
        if(h==a)
        printf("%d\n",a);
        else
