C++允许程序员为class type's object设计专门的operators,使objects的操作能够像内建型别的一样的自然而直观。让operator以种形式呈现,但符号不变,这个就是operator overloading。 Operator overloading的存在一下褒贬不一,支持者认为它使得程序代码变得更精简漂亮,反对者认为容易把程序员搞迷糊掉。但是,我想,谁都不...
C++ 运算符重载(operator overloading) 运算符重载是通过函数实现的,它本质上是函数重载。运算符重载其实就是定义一个函数,在函数内实现想要的功能,当用到这个运算符时,编译器会自动调用这个函数。#include <iostream> using namespace std; class complex{ public: complex(); complex(double real, double imag)...

The following code illustrates the use of operator overloading to implement a fraction type. A fraction is represented by a numerator and a denominator. The function hcf is used to determine the highest common factor, which is used to reduce fractions....
In C++, new features and semantics can be added to an existing software package without sweeping code changes by introducing a user-defined type using operator overloading. This approach is used, for example, to add capabilities such as algorithmic differentiation. However, the introduction of oper...

instead of "Function" or "Sub," you'll be using the "Operator" keyword in the declaration. The name of the method is simply (and always) the operator that is being overloaded. For example, the declaration in Code Block 1 declares an operator overloading for the "\" (integer division ...
Learn how to overload a C# operator and which C# operators are overloadable. In general, the unary, arithmetic, equality and comparison operators are overloadable.
