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 ...
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...
运算符重载(Operator overloading)目的:重载加号运算符能让对象之间进行运算定义重载运算符相当于定义一个函数,要用 operator 关键字开始SYNTAX返回类型 operator 运算符(参数列表)注:重载后不改变运算顺序重载后没有修改运算符优先级不改变运算变量的个数例:重载加号“+”运算符(作为成员函数)...

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...
Let's first write a program to add two co-ordinates (without using+operator overloading). classPoint:def__init__(self, x =0, y =0):self.x = x self.y = ydefadd_points(self, other):x = self.x + other.x y = self.y + other.yreturnPoint(x, y) ...
Like C++, C# allows you to overload operators for use on your own classes. This makes it possible for a user-defined data type to look as natural and be as logical to use as a fundamental data type. For example, you might create a new data type called ComplexNumber to represent a co...
