I am looking at a code example and notice some pre-processor directives using quotes and the others using brackets? What is the difference?

#ifdef WIN32
#include <windows.h>
#else // Redhat Linux Version 6.0
#include <stdio.h>
#include <stdlib.h>
#endif
#include <iostream.h>
#include <string.h>
#include "CamCoStr.hh"

`""` also look in the current directory – krzaq Oct 12 '16 at 18:22

"also" is misleading. – Lupe Oct 12 '16 at 18:26
@krzaq - that is not required. – Pete Becker Oct 12 '16 at 18:27
What? *If this search is not supported, or if the search fails, the directive is reprocessed as if it read # include < h-char-sequence> new-line* – krzaq Oct 12 '16 at 18:29
