C 複數類運算子過載

實現運算子過載有兩種形式 過載為成員函式 過載為友元函式。includeusing namespace std class complex complex double r,double i complex const complex rhs complex operator const compl...

運算子過載 複數類

1.普通運算子可以過載 2.型別過載1 防止實參被修改 2 接收隱式生成臨時物件 類內是this call的呼叫約定，成員方法隱藏this指標，指向一般為左運算元，所以只用傳右運算元即可 如下 class ccomplex 構造類內實現 的過載 右運算元型別為intconst ccomplex op...
