As mentioned previously, tp_alloc wasn’t provided by us but rather filled-in by PyType_Ready, kinda like calling the base constructor.Note that we also has a init function:highlight 複製 static int FastInt_init(FastIntObject *self, PyObject *args, PyObje...
After you create the object, call theCBaseWindow::PrepareWindowmethod to create the window.PrepareWindowis a virtual method. It callsCBaseWindow::InitialiseWindow, also a virtual method. These methods are separated from the constructor so that derived classes can override them, if necessary. ...
base-class和derived-class都沒有default constructor,compiler也過了,並且可以正常執行,所以若目前用不到default constructor,是可以省略不寫,不過這並不是一個好的practice 很多地方都要用到default constructor,而且C++又有C的built-in type的包袱,建議還是都要寫default consturctor。 28行derived-class的constructor,...

There is nothing inherently wrong with calling virtual functions from constructors and destructors. The semantics of such calls is type safe. However, experience shows that such calls are rarely needed, easily confuse maintainers, and become a source of errors when used by novices. ...
登记册关键字指定变量是要在计算机中存储的注册，如果可能的话(39)return子程序返回语句(可以带参数，也看不带参数),返回函数调用点.Terminates the execution of afunction and returns control to the calling function (or, in the case of the main function,transfers control back to the operating...
-fno-elide-constructors The C++ standard allows an implementation to omit creating a temporary that is only used to initialize another object of the same type. Specifying this option disables that optimization, and forces G++ to call the copy constructor in all cases. This option also causes ...
