运算符重载:与function overloading异曲同工的是,C++提供所谓的Operator overloading。所谓operators是像+(加)-(減)*(乘)/(除)>>(位右移) <<(位左移)之类的符号,代表一种动作。 面对operators,我们应该把他想像是一种函数,只不过形式比较特殊罢了。一般函数的参数出现在括号()之中,而operator的参数围绕着一...
Function Overloading in C++ You can have multiple definitions for the same function name in the same scope. The definition of the function must differ from each other by the types and/or the number of arguments in the argument list. You cannot overload function declarations that differ only ...

Special functions in python are the functions which are used to perform special tasks. These special functions have__as prefix and suffix to their name as we see in__init__()method which is also a special function. Some special functions used for overloading the operators are shown below: ...
文章中的解耦(又称解耦合)和模块化概念属于选读理解的概念,不需要初学者掌握。 输出对象 当类对象有多个成员变量的时候,输出这些变量往往比较麻烦。比如: Student stu("001", "张三", 18, "1990-02-12"); std::cout<<stu.m_id<<" " <<stu.m_name<<" " <<stu.m_age<<" " <<stu.m_date<<...
19行我們overload了<< operator,由於也是global function,所以也要宣告friend。 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...

Summary: Operator Overloading, new to Visual Basic 2005, simplifies the use and development of complex types by allowing you to specify your own implementation for standard operations such as addition and subtraction.

In this tutorial, we will learn about operator overloading with the help of examples. We can change the way operators work for user-defined types like objects and structures.
The operator keyword declares a function specifying what operator-symbol means when applied to instances of a class. This gives the operator more than one meaning, or "overloads" it. The compiler distinguishes between the different meanings of an operator by examining the types of its operands....
