现在让我示范一个overloaded operator的作法,只要在以下类的代码中加入第18~21行的+号的重载代码,即可完成CPoint的加法运算: 1classCPoint{23public:45CPoint()6{7_x=0;89}1011CPoint(floaty){1213_x=y;14}15floatx(){return_x;}16voidx(floatxval){_x=xval;}1718CPointoperator+(constCPoint& pt)co...

,成员指针选择(.*),casting operator。 只能够重载存在的运算符,不能够创造新的运算符。 二、通过友元函数重载数学运算符[2] 1、例子 #include <iostream> using namespace std; class Cents { private: int m_cents; public: Cents(int cents) : m_cents{cents} {}; friend Cents operator+(const Cents...
运算符重载(Operator overloading) 目的:重载加号运算符能让对象之间进行运算 定义重载运算符相当于定义一个函数,要用 operator 关键字开始 SYNTAX 返回类型 operator 运算符(参数列表) 注:重载后不改变运算顺序 重载后没有修改运算符优先级 不改变运算变量的
In Section 5.6 we introduced the idea of function overloading. Recall that a function is overloaded if there is more than one function with the same name, but the functions have different numbers of arguments or different argument types. Using similar techniques, we can overload the built-in...
The+operator, when used with values of typeint, returns their sum. However, when used with objects of a user-defined type, it is an error. In this case, we can define the behavior of the+operator to work with objects as well.

How to Use Operator Overloading? Suppose we want to use the+operator to add two user-defined objects. Since the+operator internally calls the__add__()method, if we implement this method in a class, we can make objects of that class work with the+operator. ...
