现在上面的代码离我们期待的连续输出还有最后一步,那就是去掉output这个函数,改为<<输出操作符。 这件正是输出操作符重载的含义:对象通过重载一个叫做输出操作符的函数来实现上面output的功能,从而可以给任何ostream的派生类(比如,cout,ofstream,ostringstream)对象无差别的输出。 输出操作符重载 我们可以通过实现一个函数(输出操作

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 ...
For example, we can directly use the = operator to copy objects of the same class. Here, we do not need to create an operator function. 2. We cannot change the precedence and associativity of operators using operator overloading. 3. We cannot overload following operators in C++: :: (...
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)...

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...
Python does not limit operator overloading to arithmetic operators. We can overload comparison operators as well. Here's an example of how we can overload the<operator to compare two objects of thePersonclass based on theirage: classPerson:def__init__(self, name, age):self.name = name ...

When overloading operators, it’s best to keep the function of the operators as close to the original intent of the operators as possible. Furthermore, because operators don’t have descriptive names, it’s not always clear what they are intended to do. For example, operator+ might be a...
