please explain the difference between
#include "htc.h" and #include<pic.h>
#include "htc.h" and #include<pic.h>
#include "filename"

#include <filename>
An "implementation-defined rule" means you need to RTFM for your specific compiler.K&R said:If the filename is quoted, searching for the file typically begins where the source program was found; if it is not found there, or if the name is enclosed in < and >, searching follows an implementation-defined rule to find the file.
