#include “windows.h”

#include "iostream.h"

class MyTimer

{ private:

int hour

int minute

int sec

public:

MyTimer():hour(0),minute(0),sec(0){}

MyTimer(int h, int m, int s)

{ hour = h

minute = m

sec = s

}

void setTime(int h, int m, int s)

{ hour = h

minute = m

sec = s

}

void showTime()

{ while(1)

{ system("cls")

if(sec>=60)

{ sec = sec-60

minute +=1

}

if(minute>=60)

{ minute = minute-60

hour +=1

}

if(hour >=24)

{

hour = hour-24

}

cout<<hour<<":"<<minute<<":"<<sec<<endl

Sleep(1000)

sec++

}

}

}

在主函数创建一个MyTimer对象后调用showTime就行了
