控制台显示时钟

看到有同学发帖子:http://student.csdn.net/space.php?uid=348855&do=thread&id=8517  试着写一下．

如果要获得目前的时间并转换成时分秒,需要自己想办法做转换啦.

 

#include
using namespace std;
#include

typedef unsigned int uint;

class Clock
{
public:


    Clock(uint h=0, uint m=0, uint s=0)
    :hour(h), minute(m), second(s)
    {
    }


    void Set()
    {
        cout << "请输入当前时间(时,分,秒),以空格分隔，以回车结束:" << endl;
        cin >> hour >> minute >> second;
    }

    void Run() //每隔一秒时间变动一次
    {

        uint old = time(NULL);

        while(true)
        {
            if (time(NULL) != old)
            {
                old = time(NULL);

                //加一秒
                if (second == 59)
                {
                    second = 0;
                    if (minute == 59)
                    {
                        minute = 0;
                        if (hour == 23)
                            hour = 0;
                        else
                            hour++;
                    }
                    else
                        minute++;
                }
                else
                    second++;

                system("cls"); //清屏
                Show();
            }



        }
    }

private:
    void Show(uint n) const
    {
        if (n < 10)
            cout << '0' << n;
        else
            cout << n;
    }

    void Show() const//显示时间
    {
        Show(hour);
        cout << ':';
        Show(minute);
        cout << ':';
        Show(second);
        cout << endl;
    }


private:
    uint hour;
    uint minute;
    uint second;
};

int main()
{
    Clock ck;
    ck.Set();
    ck.Run();
}
