那时觉得operator比较好玩。C++有时它的确是个耐玩的东东。operator它有两种用法,一种是operator overloading(操作符重载),一种是operator casting(操作隐式转换)。1.operatoroverloading C++可以通过operator 重载操作符,格式如下:类型Toperator操作符 (),如比重载+,如下所示 [cpp] view plaincopy template<typename ...
最後49行和55行的user code,直接用+和*就可以計算複數,而且cout也直接支援Complex物件,非常清楚,這就是operator overloading的威力,不過,在class implementation時,operator overloading的語法不是很好寫,雖然語法很有邏輯很有道理,但就是太臭太長了,還真的得時間熟悉才行。 ...
重载操作符 operator overloading 学习笔记 重载操作符,只是另外一种调用函数的方法和表现方式,在某些情况它可以让代码更简单易读。注意不要过度使用重载操作符,除非它让你的类更简单,让你的代码更易读。 1语法 如下: 其中友元,关键字不是必须的,但是当你需要读参数类的内部变量时候,声明就需要加上friend. friend ...

There's no syntax for using the increment or decrement operators to pass these values other than explicit invocation, as shown in the preceding code. A more straightforward way to implement this functionality is to overload the addition/assignment operator (+=). See also Operator OverloadingFeed...

For up-to-date information on C++, see the main reference at cppreference.com. Operator overloading in C++ allows us to write natural expressions like d = a + b / c; with our own classes. The above expression could be equal to d = a.add(b.divide(c)); which results in hard ...
In my program, I have a class Route. It has a vector<string> property. After an initial vector has been populated, the user may have to concatenate another vector<string> to that initial vector. How can I overload the '+' operator to add to Route objects together and return the concat...
