一开始WA了好多遍后来发现是自己的少了中间为零的判断~

#include<stdio.h>
#include<string.h>
int main()
{
    char s[1000],o;
    long a,res[1000];
    
    while(scanf("%s %c %ld",s,&o,&a) != EOF)
    {
        long len,num,i,j,count;
        num = 0;
        len = strlen(s);
        count = 0;
        int leap;
        if(o == '/')
        {
            num = 0;
            leap = 0;
            for(i = 0;i < len;i++)
            {
                num = num*10 + s[i]-'0';
                if(num/a && leap == 0)
                {
                    res[count++] = num/a;
                    num = num%a;
                    leap = 1;
                }
                else if(leap)
                {
                    res[count++] = num/a;
                    num = num%a;
                }

            }
            if(count == 0)
                res[count++] = 0;
        }
        else
        {
            for(i = 0;i < len;i++)
            {
                num = num*10 + s[i]-'0';
                num = num%a;
            }
            res[count++] = num;
        }
        for(i = 0;i < count;i++)
            printf("%ld",res[i]);
        puts("");

    }

    return 0;
