//運算子重寫 /*operator是C#、C++和pascal的關鍵字，它和運算子一起使用，表示一個運算子函式，理解時應將operator和運算子整體上視為一個函式名。 過載運算子的函式一般格式如下
函式型別 operator 運算子名稱 （形參表列）
{對運算子的過載處理}
例如，想將“+”用於Complex（複數）的加法運算，函式的原型可以是這樣的：
Complex operator + (Complex & c1,Complex &c2);
operator+函式表示對運算子+過載。 其中，operator是關鍵字，專門用於定義過載運算子的函式的，運算子名稱就是C++提供給使用者的預定運算子。
注意：函式名是由operator和運算子組成。 */
