如何实现一个模拟时钟
#include<iostream>
#include<windows.h>
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<<h<<':'<<m<<':'<<s<<" ";
Sleep(1000);
cout<<'\r';
if(!(s=++s%60))
if(!(m=++m%60))
h=++h%24;
}
} int main()
{
Clock A(23,59,55);
A.displayTime();
return 0;
}
