C语言 用devc++编写一个模拟时钟，最简单那种就行，但要能在devc++上运行。

#include
#include
using namespace std;
class Clock{
    public:
        Clock(short h=0,short m=0,short s=0):h(h),m(m),s(s){
        }
        void displayTime();
    private:
        short h;
        short m;
        short s;
};void Clock::displayTime(){
    while(true){
        cout<        Sleep(1000);//一秒更新一次 
        cout<<'\r';
        if(!(s=++s%60))
            if(!(m=++m%60))
                h=++h%24;
    }
} int main()
{
    Clock A(12,20,30);//初始时间
    A.displayTime();//更新函数
    return 0;
}
/*
12:20:30
