I have a C++ program (.cpp) inside which I wish to use some of the functions which are present inside the C header files such as stdio.h, conio.h, stdlib.h, graphics.h, devi
For a list of C standard C headers (stdio, stdlib, assert, ...), prepend a c and remove the .h. For example stdio.h becomes cstdio.
For other headers, use
extern "C" { #include "other_header.h" }
