Arduino - C ++对象构造函数错误

时间:2015-07-13 00:25:36

标签: c++ arduino

我正在尝试调试我的一些arduino代码并不断收到与对象构造函数相关的错误。我相信我已经正确定义了所有内容并提供了正确的输入,但我仍然无法获得编译代码。

我粘贴了下面的错误和代码。请注意,我已在“数据控件”类中删除了一些源代码。另请注意,CDOS_Info是我创建的结构。

感谢您的帮助!

错误:

答案 0 :(得分:2)

您无法在不调用其构造函数的情况下创建对象。由于StateController也是DataControl,因此您无需调用DataControl的构造函数(以及StateController&#39; S)。但是该构造函数接受了一个参数,因此编译器无法为您添加调用。

调用基类的构造函数的方法是修改派生类的构造函数,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();
}

注意奇怪的语法 - 这不是一个普通的函数调用。是的,它 超出了大括号。
