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

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)...
运算符重载:与function overloading异曲同工的是,C++提供所谓的Operator overloading。所谓operators是像+(加)-(減)*(乘)/(除)>>(位右移) <<(位左移)之类的符号,代表一种动作。 面对operators,我们应该把他想像是一种函数,只不过形式比较特殊罢了。一般函数的参数出现在括号()之中,而operator的参数围绕着一...
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++: :: (...
【转】Operator Overloading Thinking in C++, 2nd ed. Volume 1 ©2000 by Bruce Eckel Unary operators The following example shows the syntax to overload all the unary operators, in the form of both global functions (non-member friend functions) and as member functions. These will expand upon...
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 ...

c) Polymorphism(多态性)**选项分析** 1. **继承(a)**:继承是面向对象中类与类之间的层次关系,允许子类复用父类的属性和方法,与操作符重载无直接关联。2. **信息传递(b)**:信息传递通常指对象间通过方法调用交互,属于面向对象的基础概念,但并非操作符重载的范畴。
