c 中物件的複製就如同 轉殖 用乙個已有的物件快速地複製出多個完全相同的物件。一般而言，以下三種情況都會使用到物件的複製 1 建立乙個新物件，並用另乙個同類的已有物件對新物件進行初始化，例如 cpp view plain copy class rect rect rect1 rect rect2 r...
淺拷貝與深拷貝
淺拷貝 1 2 myclass a,b a b 為了封裝性和解耦，同型別的兩個物件之間進行賦值操作時，所有成員變數被複製，包括私有成員 指標變數。類的成員函式在傳遞或返回物件時都會進行物件複製產生臨時物件，比如函式呼叫時實參變為形參，以及函式返回物件。考慮到效能和使用者要求不同，編譯器不複製物件內部...
