how to use user defined library the same way we use pre-defined libraries

Question

i mean while using user defined libraries in c we write:

#include "libname.h"

but for predefined libraries we use angular brackets instead of quotes.

#include <libname.h>

I want to include my library in predefined libraries and want use them in the same way we use predefined libraries.

Just remove `.h` from your header file name. I'm not sure why you'd want to do that though — Alan Birtles, Jun 07 '20 at 06:44

Every compiler supports a way for including additional directories. And any file contained in these directories will be able to be included with its name enclosed by angular brackets.

For example gcc provides -I option:

gcc -ImyPath myfile.c ...

If myHeader.h is contained in myPath directory, myfile.c can include it in this way

#include <myHeader.h>

Check the guide of your compiler to discover how this is achieved by it. If you are using a graphical IDE you will find for sure this capability in your project option (check compiler options).
