这个是求水仙花数的

把m=d该为d=m看一下

scanf("&d,&d",&m,&n)!=EOF这里也需要该一下scnaf("%d%d",&m,&n)

#include<stdio.h>
int main()
 {
     int a,b,c,s,d,k,m,n,t=0;
     while (scanf("%d,%d",&m,&n)!=EOF)
     {
         if (m>n)
         {
            m=d;
            m=n;
            n=d;
         }
 
   
        for (k=m;k<=n;k++)
         {    a=k/100;
         b=k%100/10;
         c=k%10;
         s=a*a*a+b*b*b+c*c*c;
         if(s==k)
         {
             printf("%d",k);
             t++;
             printf("\n");
         }
         }
         if (t==0)
             printf ("no\n");
     }
     return 0;
 }

#include<stdio.h>
int main()
{
    int a,b,c,s,d,k,m,n,t=0;
    while (scanf("%d,%d",&m,&n)!=EOF)
    {
        if (m>n)
        {
            d=m;
            m=n;
            n=d;
        }
        
        for (k=m;k<=n;k++)
        {   
            a=k/100;
            b=k%100/10;
            c=k%10;
            s=a*a*a+b*b*b+c*c*c;
            if(s==k)
            {
                printf("%d\n",k);
                t++;
            }
        }
        if (t==0)
            printf ("no\n");
        else
            printf ("\n");
    }
    return 0;
}

#include<stdio.h>
int main()
{
    int a,b,c,s,d,k,m,n,t=0;
    while (scanf("%d%d",&m,&n))
    {
        if (m>n)
        {
           d=m;
           m=n;
           n=d;
        }

   
        for (k=m;k<=n;k++)
        {    a=k/100;
        b=k%100/10;
        c=k%10;
        s=a*a*a+b*b*b+c*c*c;
         if(s==k)
         {
             printf("%d ",k);
             t++;
         }
        }
        if (t==0)
            printf ("no\n");
        else
            printf ("\n");
    }
    return 0;
}
这个程序得输出介于这两个数中间的水仙花数

各位的意见好像都不可以呀

#include<stdio.h>
int main()
{
    int a,b,c,s,d,k,m,n,t;
    while (scanf("&d &d",&m,&n)!=EOF)
    {    t=0;
        if (m>n)
        {
           d=m;
           m=n;
           n=d;
        }
        for (k=m;k<=n;k++)
        {    a=k/100;
        b=k%100/10;
        c=k%10;
        s=a*a*a+b*b*b+c*c*c;
        s==k?printf ("%d",s),t++:t=t;
        }
        if (t==0)
            printf ("no\n");
        else
            printf ("\n");
    }
    return 0;
}

我的程序修改成上面这样，为什么输入100 120 结果是无限个no

#include<stdio.h>
int main()
{
    int a,b,c,s,d,k,m,n,t;
    while (scanf("%d%d",&m,&n)!=EOF)
    {    t=0;
        if (m>n)
        {
           d=m;
           m=n;
           n=d;
        }
        for (k=m;k<=n;k++)
        {    a=k/100;
        b=k%100/10;
        c=k%10;
        s=a*a*a+b*b*b+c*c*c;
        s==k?printf("%d ",k),t+=2:1;
        }
        if (t==0)
            printf ("no\n");
        else
            printf ("\n");

    }
    return 0;
}
你的那个输入有问题，应该输入是%而不是&。
