C - Header Files

A header file is a library file which contains function declarations and macro definitions which can be used in source program. Header files is saved with an extension '.h'.

The Benefits of using header file is that you can reuse the function's and macro's in multiple program files without redeclaring it.

In C/C++, there are 41 predefined header files available.

List of C/C++ Header Files
alloc.h assert.h bcd.h bios.h
complex.h conio.h ctype.h dir.h
dirent.h dos.h errno.h fcntl.h
