Add Model reference to View

In Model View Controller in the context of Cocoa, when View(PolygonView) needs a reference to Model(PolygonShape):
Step 1: declare an instance variable of PolygonShape in PolygonView



Step 2 Link the Outlet PolygonShape to Class PolygonShape

#include vs #include "file"

First: <> vs ""
Both would work if file exist. The difference is the order of directories are searched.
In case of <>: ONLY searches in list of SYSTEM directories. If file does not exist in the system directories then C1083 error.

In case of "file": First searches in the including file directory(current file directory), if not found then searches in the SYSTEM directories. If either is found then C1083 error.

Second: file vs file.h
Some of the header files end with ".h" others do not. Eg stdio.h vs fstream .Both of the files are in system directory so proper inclusion would be
#include
#include

of course the following would work as well
#include "stdio"
#include "fstream.h"

See picture for more clarification example





verifies files are in system directory
