加号运算符重载
运算符重载的本质是
//成员函数重载本质调用 Person p3 = p1.operator+(p2); Person p3 = p1 +p2; //全局函数重载本质调用 Person p3 = operator+(p1,p2); //需注意 运算符重载 也可以发生函数重载 Person p3 = p1 +10;//person 数据类型 + int Person operator+(Person &p1,int num){ Person temp; temp.m_A = p1.m_A +num;
temp.m_B = p1.m_B +num;
return temp; }
左移运算符重载
//只能利用全局函数重载左移运算符 ostream & operator <<(ostream &cout,Person &p) //本质 operator << (cout,p) 简化 cout<<p { cout <<"m_A=" << p.m_A <<"m_B=" <<p.m_B; return cout; } void test01() { cout <<p <<endl;//链式编程思想 }
