完美c++疑难解答-重载运算符号.txt

完美C++疑难解答 详细的讲解了C/C++编程过程中的一些难点和容易混淆的地方！值得收藏反复研究。

1直观、对数据成员进一步功能上封装...
Time aTime;
aTime.AddObject(bTime,cTime)      aTime=bTime+cTime;
一个函数都具备:返回值+参数列表+其余根据特点 进行不断扩充....
比如int WinAPI WinMain(); Time Operator -();

2.参数个数..
一元  成员函数  operator++();//this
      友元函数  operator++(Object &);
来做一下吧:

 #include "stdafx.h"
//Show(): 显示日期--class Day  ;  显示时间  class Time

class Time
{
public:
	Time(int hour,int min,int second);
	Time();
	void operator==(const Time & time1);
	friend void operator==(Time &time2,const Time &time3);
private:
	int m_hour,m_min,m_second;
};
Time::Time()
{
}

Time::Time(int hour,int min,int second)
{
	m_hour=hour;
	m_min=min;
	m_second=second;
}
void Time::operator==(const Time &time1)
{
	m_hour = time1.m_hour;//this->是指向整个类的..哈哈...
	m_min  = time1.m_min;
	m_second = time1.m_second;
	cout<<m_hour<<":"<<m_min<<":"<<m_second<<endl;	
}
void operator==(Time &time2,const Time &time3)
{
	time2.m_hour = time3.m_hour;//this->是指向整个类的..哈哈...
	time2.m_min  = time3.m_min;
	time2.m_second = time3.m_second;
	cout<<time2.m_hour<<":"<<time2.m_min<<":"<<time2.m_second<<endl;	
}


void main()
{
	Time time1(16,17,44);
	Time time2,time3;
	time2.operator ==(time1);
	operator==(time3,time1);
}
