what is mode 13 in C++ and how can I use it?

Question

It's related to graphic in C++

Answer 1

Mode 13h is a VGA mode, not specific to C++ at all. In fact, a better mode is known as "Mode X".

With advent of DirectX, Mode X and Mode 13h programming is obsolete. Are you SURE you want to learn about that?
