the question should be like that.

#include<header.h> - system defined
#include "header.h" - user defined

the difference between these two header lines is that the first header line ( #include<header.h> ) fines the specific file in the system include file and the second header line( #include "header.h" ) fines the specific file in the
current development folder.

Basically the difference is in the preprocessor search path for the file. See What is the difference between #include <filename> and #include “filename”[^] at stack overflow.

Note that header and header.h are different files.
