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,谁都不可否认下面这样的程序代码确实是精简漂亮: CString str1("Hello, I am J.J.Hou,"); CString str2("How ...
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)...
Note: When we overload operators, we can use it to work in any way we like. For example, we could have used ++ to increase value by 100. However, this makes our code confusing and difficult to understand. It's our job as a programmer to use operator overloading properly and in a...
In this way, + is overloaded with different operations depending upon the data. Source Code using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace OperatorOverloading { class Rectangle { static void Main(string[] args) { Rectangle objRect1 = new Rec...
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 to read code. Operator overloading by Example This example will add basic arithmeti...

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 + ...
说明:本文重点是掌握输出操作符重载的代码写法。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: Studentstu("001","张三",18,"1990-02-12");std::cout<<stu.m_id<<" "<<stu.m_name<<" "<<stu....
The database access library SOCI also overloads operator,. The member access through pointer to member operator->*. 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 ...
. The only differences between the similar functions are highlighted. Such code duplications can be reduced and sometimes avoided altogether by string mixins. We will see themixinkeyword in a later chapter as well. I would like to show briefly how this keyword helps with operator overloading....
