what makes const at the lower levels of the machine?
When making something const in C++ what makes it that you cannot for example implicitly pass it a non-const at the lower levels of the machine? How is it determined by the machine that this is const? (besides the fact that const means what it means...) Is it perhaps stored in the .rdata section of memory or is there a bit that gets se...

C++ input question
Hello! I am attempting to build a small local-purpose 3d engine, which has to be platform-independent and right now I'm looking for a way to handle different possible types of user input.

I have tons of existing code using wxWidgets. The main window is wxDialog. Now I have to add a wxMenuBar to that dialog. But, in order to do it, the window should be derived from wxFrame.

If you omit the second integer, the value 0 is passed instead. I am now looking for ways to obtain the same functionality, but from the callee's side. Suppose I have an int...
