Simple time display

brief introduction

A simple analog time display, the principle is to use the time function to obtain the current time , and then through the time update function and the time display function to simulate the time update, the alternate display of time uses the clear screen function system ("CLS");

head File

#include <iostream>
#include <time.h>
using namespace std;

class Curtime {
    
    
	int h;
	int m;
	int s;//时 分 秒
public:
	void SetTime();//设置起始时间
	void DisplayTime();//显示时间
	void UpdateTime();//更新时间
};

Function implementation

#include "disTime.h"

void Curtime::SetTime() {
    
    
	time_t tt = time(NULL);
	tm* t = localtime(&tt);
	h = t->tm_hour;
	m = t->tm_min;
	s = t->tm_sec;	
}

void Curtime::DisplayTime() {
    
    
	system("cls");
	cout << "当前时间：" << h << " 时" << " " << m << " 分" << s << " 秒";
}

void Curtime::UpdateTime() {
    
    
	_sleep(1000);//模拟延时
	if (++s == 60) {
    
    
		s = 0;
		if (++m == 60) {
    
    
			m = 0;
			if (++h == 24)
				h = 0;
		}
	}
}

Function usage

#include <iostream>
#include"disTime.h"
using namespace std;

int main() {
    
    
	Curtime tm;
	tm.SetTime();
	for (int i = 0; i < 100; i++) {
    
    
		tm.DisplayTime();
		tm.UpdateTime();
	}
	return 0;
}
