#include<stdio.h>

int main()
{
    int h=0,m=0,s=0,n=0;
    while(1)
    {

        printf("\r%02d:%02d:%02d",h,m,s++);     //计时器
        Sleep(1000);      

            if(s==60)
            {
                m++;
                s=0;
                if(m==60)
                {
                    h++;
                    m=0;
                    if(h==24)
                        return 0;
                }
            }
            // 每60秒响一次，一次响5声
        if (s%60==0)
        {
            while(n<5)       //n是声音的次数
            {
                  printf("%c",'\a');      //\a是输出“哔”的声音
                  n++;
            }
            n=0;
        }
    }

        return 0;
}

那是不是我编译器的问题，它运行后响一次就卡住，而且关不了。
