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...

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)...
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....
Overloading the Binary + Operator Following is a program to demonstrate the overloading of the+operator for the classComplex. // C++ program to overload the binary operator +// This program adds two complex numbers#include<iostream>usingnamespacestd;classComplex{private:floatreal;floatimg;public...
So we can see that the+operator is not supported in a user-defined class. But we can do the same by overloading the+operator for our classComplex. But how can we do that? 因此,我们可以看到用户定义的类中不支持+运算符。 但是我们可以通过为类Complex重载+运算符来做到这一点。 但是,我们该...

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.F# نسخ ...
