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;
    }
