# include <stdio.h>

bool Isprime(int val)

    {
        if (val%i == 0)
            break;
    }
    if (val == i || val == 1)
        return true;
    else
        return false;
}

int main(void)
{
    int m;
    char ch;
do
{
    scanf("%d",&m);

    if (Isprime(m))
   
        printf("yes\n");
    else
        printf("no\n");
    printf("继续请按Y，结束请按N\n");
    scanf(" %c",&ch);
} while ("y" == ch||"Y" == ch);
    return 0;
}
以上代码哪里出错....求教....

do
{
    scanf("%d",&m);

    if (Isprime(m))
   
        printf("yes\n");
    else
        printf("no\n");
    printf("继续请按Y，结束请按N\n");
    scanf(" %c",&ch);
} while ('y' == ch||'Y' == ch);

呵呵  李兄弟真是仔细  我第一眼还真没看出来

这种问题根据错误不是可以马上知道在哪里出错么

那里写了5个error
