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. * assign 0 or 1 to TEST_EQ, look the dif…

Operator Overload NOTE1:  operator = must be overload as a member function NOTE2: An operator function must either be a member of a class or have at least one parameter of class type. //操作符重载,有一个最基本条件,就是一定有一个一元是一个自定义的C++类//如果两个都是基本数据类型操作符重载是非法的 NOTE3…

原文阅读:<算法(第四版)>第一章 第一节:基础编程模型 有没有在面试的时候被问到:下面这几行代码的执行结果是什么?依据是什么? System.out.println (5/3); System.out.println ((double)(5/3)); System.out.println (5/3.0); System.out.println (5.0/3.0); System.out.println ((int)5/(double)3); 这个问题涉及到的概念有:运算符重载和类型转换. 对…

C++中的operator主要有两个作用,一是操作符的重载,一是自定义对象类型的隐式转换.对于操作符的重载,许多人都不陌生,但是估计不少人都不太熟悉operator的第二种用法,即自定义对象类型的隐式转换,我们下面就用以下这个小例子温故一下这两种用法: #include <iostream> #include <sstream> using namespace std; class FuncObj { public: FuncObj(int n): _n(n) { cout <…

Every operator overload that we use in C#, gets converted to a function call in IL. Theoverloaded > operator translates into the function op_GreaterThan and a + gets convertedto op_Addition etc. In the first program of this chapter, we have overloade…

思考:在C++类中,通过设计类的构造和析构函数,就已经把复杂的内存管理起来了. 及时是简单的结构体,也是有构造和析构函数的,而下面这种情况,可以在非结构中使用. /** Operator Overload new and delete */ #include <iostream> #include <cstdlib> #include <new> using namespace std; class MyClass{ public: MyClass(){ x = y =…

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: + * / % ^ & | ~ ! = < > += = *= /= %= ^= &= |= << >> >>= <<= == != <=>= && || ++ >* , > [] (…

1. Different Kinds  of Type Members        A type can define zero or more of the following kinds of members:        Constants           A constant is a symbol that identifies a never-changing data value        Fields           A field represents a re…

1. Primitive Types        Any data types the compiler directly supports are called primitive types.        Primitive types map directly to types existing in the Framework Class Library (FCL).        For the types that are compliant with the Common La…
