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.operator overloading C++可以通过operator 重载操作符,格式如下:类型T operator 操作符 (),如比重载+,如下所示 [cpp]view plaincopy template<typename T>class A { public: const T operator + (const...

http://www.cs.caltech.edu/courses/cs11/material/cpp/donnie/cpp-ops.html One of the nice features of C++ is that you can give special meanings to operators, when they are used with user-defined classes. This is calledoperator overloading. You can implement C++ operator overloads by provid...
There are no specific downsides to overloading this operator, but it is rarely used in practice. It was suggested that it could be part of a smart pointer interface, and in fact is used in that capacity by actors in boost.phoenix. It is more common in EDSLs such as cpp.react. ...
Operator Overloading讓我們可以自己定義Operator的功能,讓程式可以更精簡,C#也有,不過不是很強調,但C++非常強調Operator Overloading,這是C++的一大特色。 Introduction 以下程式我們試著實做一個『複數』型別,複數由實部,有虛部,複數的加法為(a + bi) + (c +di) = (a +c) + (b+d)i,乘法則是(a + ...

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 ...
