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 ...
One of the nice features of C++ is that you can give special meanings to operators, when they are used with user-defined classes. This is calledoperator overloading. You can implement C++ operator overloads by providing special member-functions on your classes that follow a particular naming ...
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: Student stu("001", "张三", 18, "1990-02-12"); std::cout<<stu.m_id<<" " <<stu.m_name<<" ...
I tried overloading the "<<" operator, like this: // in Platform.cpp std::ostream& operator<<(std::ostream& out, Platform* p ) { out << "Platform: xi=" << p->getxi() << ", xf=" << p->getxf() << std::endl; return out; } But this just prints a memory address ...
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)...

1.operator是操作符的意思。operator是C++的关键字，不是C语言当中的，它和运算符一起使用，表示一个运算符函数，理解时应将operator=整体上视为一个函数名。2.C++中的operator，有两种用法，一种是operator overloading（操作符重载），一种是operator casting（操作隐式转换）。下面分别进行介绍：1)...
Learn how to overload a C# operator and which C# operators are overloadable. In general, the unary, arithmetic, equality and comparison operators are overloadable.
废话不多说,这次讲的是 Operator overload. 关于operator, 在 < The C++ Programing Language > 里的描述,可以用做overload的如下: + * / % ^ & | ~ ! = < > += = *= /= %= ^= &= |= << >> >>= <<= == != <= >= && || ++ >* , > [] () new new[] delete delete[]...
