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...
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...

Operator Overloading讓我們可以自己定義Operator的功能,讓程式可以更精簡,C#也有,不過不是很強調,但C++非常強調Operator Overloading,這是C++的一大特色。 Introduction 以下程式我們試著實做一個『複數』型別,複數由實部,有虛部,複數的加法為(a + bi) + (c +di) = (a +c) + (b+d)i,乘法則是(a + ...

The operator keyword declares a function specifying what operator-symbol means when applied to instances of a class. This gives the operator more than one meaning, or "overloads" it. The compiler distinguishes between the different meanings of an operator by examining the types of its operands....
