我是靠谱客的博主有魅力乌龟，最近开发中收集的这篇文章主要介绍Time 类可以实现调整和重新设置，显示时间，将两个时间相加的功能，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

可以计算两个时间段的相加减，以及operator+（）的使用方法：

以下是程序：

myTime.h

#include<iostream> 
#ifndef MYTIME1_H_
#define MYTIME1_H_

class Time
{
	private:
		int hours;
		int minutes;
	public:
		Time();
		Time(int h, int m=0);
		void AddMin(int m);
		void AddHr(int h);
		void Reset(int h=0, int m=0);
		Time operator+(const Time & t) const;
		void Show() const;
};
#endif

myTime.cpp

#include"myTime.h"

Time::Time(){
	hours=minutes=0;
}

Time::Time(int h, int m){
	hours=h;
	minutes=m;
}

void Time::AddMin(int m){
	minutes+=m;
	hours+=minutes/60;
	minutes%=60; 
}

void Time::AddHr(int h){
	hours+=h;
}

void Time::Reset(int h, int m){
	hours=h;
	minutes=m;
}

Time Time::operator+(const Time& t) const{
	Time sum;
	sum.minutes=minutes+t.minutes;
	sum.hours=hours+t.hours+sum.minutes/60;
	sum.minutes%=60;
	return sum; 
}

void Time::Show()const{
	std::cout<<hours<<"hours"<<minutes<<"minutes";
}

myTimeTest.cpp

#include<iostream>
#include"myTime.h"
int main(){
	using std::cout;
	using std::endl;
	Time planning;
	Time coding (2,40);
	Time fixing(5,55);
	Time total;
	
	cout<<"planning time =";
	planning.Show();
	cout<<endl;
	
	cout<<"coding time =";
	coding .Show();
	cout<<endl;
	
	cout<<"fixing time =";
	fixing.Show();
	cout<<endl;
	
	total=coding + fixing;
	cout<<"coding + fixing =";
	total.Show();
	cout<<endl;
	
	Time moreFixing (3,28);
	cout<<"more fixing time =";
	moreFixing.Show();
	cout<<endl;
	total=moreFixing.operator+(total);
	cout<<"moreFixing.operator+(total) =";
	total.Show();
	cout<<endl;
	
	return 0;
}
