In C++, the const keyword can be used with class member functions to indicate that the function does not modify the object’s state. A const member function can be used on a const object, but it is not permitted to change any of the class’ non-static data members. Here’s an example...
The keyword__attribute__allows you to specify special attributes when making a declaration. This keyword is followed by an attribute specification inside double parentheses. The following attributes are currently defined for functions on all targets:noreturn,noinline,always_inline,pure,const,nothrow,senti...
In the program above, the constcisuntypedand has a value5.You may be wondering what is the default type of c and if it does have one, how do we then assign it to variables of different types. The answer lies in the syntax ofc. The following program will make things more clear. 1pa...

https://isaratech.com/ue4-declaring-and-using-interfaces-in-c/ Unreal Engine interfaces 当我们使用C++/Java,或者任何面向对象程序语言,我们经常使用到interface这个概念。在C++中,interface一般通过没有成员的抽象类来实现,只包含pure virtual functions. ...
To declare a constant member function,place the const keyword after the closing parenthesis of the argument list.The const keyword is required in both the declaration and the definition.A constant member function cannot modify any data members or call any member functions that aren't constant. ...
function; the ON_WM_XXXmacros create message map entries with the proper enum codes; and CWnd::OnWndMsg uses the codes to convert WPARAM and LPARAM values to MFC objects before calling your handler function. The result is that your handler functions can deal with MFC objects instead of raw ...
