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 ...
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<<...

运算符重载(Operator overloading)目的:重载加号运算符能让对象之间进行运算定义重载运算符相当于定义一个函数,要用 operator 关键字开始SYNTAX返回类型 operator 运算符(参数列表)注:重载后不改变运算顺序重载后没有修改运算符优先级不改变运算变量的个数例:重载加号“+”运算符(作为成员函数)...
To avoid this complexity, some libraries opt for overloading operator() instead, so that 3D access expressions have the Fortran-like syntax a(i, j, k) = x;. (until C++23) operator[] can take any number of subscripts. For example, an operator[] of a 3D array class declared as T...

Syntax for Operator Overloading To overload an operator, implement the corresponding trait for your type. Each trait requires defining a specific method, such as add for the Add trait. use std::ops::{Add}; // Import the Add trait
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...
