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)...
Reason to Overload Operators Using Friend Function We can also overload the operators using a member function instead of a friend function. For example, classComplex{…..public: Complexoperator+ (constComplex& obj){ Complex temp; temp.real = real + obj.real; temp.img = img + obj.img;ret...
C++ operator overload -- 操作符重载 2011-12-13 14:18:29分类: C/C++ 操作符重载有两种方式,一是以成员函数方式重载,另一种是全局函数。先看例子#include <iostream>#include <string>using namespace std;/* defualt operator= differ from my own one....
This example shows how you can use operator overloading to create a complex number class Complex that defines complex addition. The program displays the imaginary and the real parts of the numbers and the addition result using an override of the ToString method....
Output streams use the insertion (<<) operator for standard types. You can also overload the << operator for your own classes.ExampleThe write function example showed the use of a Date structure. A date is an ideal candidate for a C++ class in which the data members (month, day, and ...
Operator overloading is the ability for you to define procedures for a set of operators on a given type. This allows you to write more intuitive and more readable code. The operators that can be defined on your class or structure are as follows:...
add(b.divide(c)); which results in hard to read code. Operator overloading by Example This example will add basic arithmetic operations: addition, subtraction, multiplication and division to Complex number class. These operations will use operators: +, -, *, / and their assigning ...
