[英]Arduino - C++ Object Constructor Error
我正在嘗試調試一些arduino代碼,並不斷獲取與對象構造函數相關的錯誤。 我相信我已經正確定義了所有內容並提供了正確的輸入,但是我仍然無法編譯代碼。
我在下面粘貼了錯誤和代碼。 請注意,我已經刪除了“數據控件”類中的某些源代碼。 另請注意,CDOS_Info是我創建的結構。
謝謝你的幫助!

您必須先調用其構造函數才能創建對象。 因為StateController
也是DataControl
,所以如果不調用DataControl
的構造函數(以及StateController
的構造函數),就無法創建一個。 但是該構造函數帶有一個參數,因此編譯器無法為您添加調用。
調用基類的構造函數的方法是修改派生類的構造函數,如下所示:
StateController::StateController(CDOS_Info *inputtedInfo)
: DataControl(inputtedInfo) // calls DataControl's constructor
{
// info = inputtedInfo; // Don't need this, because DataControl's constructor does it.
userInput = InputInterface();
dataControl = DataControl(info);
lightController = LEDController();
}
請注意奇怪的語法-這不完全是正常的函數調用。 是的,它確實超出了大括號。
