[Solved] how to use the keys F1 to F10 in C code

Question

For Windows, there is the _getch function, which returns the bytes of a key code, one by one. You can get a function key that way, detecting it by the presence of certain codes: 0x00 or 0xe0 as shown in the example in [C\C++] – how get arrow keys(correctly) using getch()?. When _getch returns one of those, the next byte is normally a virtual key code.

For making sense of those codes, the place to start reading is the Keyboard Input Reference, looking for virtual keys. Microsoft provides a list here: Virtual-Key Codes

Some people might advise starting with getch, but Microsoft provides this only for legacy use (does not recommend its use in new programs due to conflict with POSIX, and provides _getch as the alternative).
