hi! i've done c++ using existing libraries and whatever before, but never made my own project completely from scratch - i'm trying to learn that at the moment so that i can improve my competency with c++. having issues trying to do #include <customheader.h>. apparently it doesn't exist, even though i have made sure it's included in the project from the context menu. i'm using Visual Studio. lpp

any suggestions would be really appreciated! 🙂

screencap of the solution explorer, in case it's useful

okay i've figured it out now, my syntax was wrong - should use quotation marks, not arrow brackets for local files

#

@fleet topaz sorry if you had a solution in mind already.

no worries, it's been a while since I was on VS (on Mac & Linux for a while) but I'll leave this here in case.

There is a difference between #include <some_header.h>
and #include "some_header.h"...

The first way will try to get a header from the system include directory, likely outside the project. The second way will try to get a header within the project directory. 👍
