It seems that now-a-days Google is not what it once was with all the mucked up searches. I am in need of advice as I am a noob of sorts with Mac development. I am designing a advanced GUI installer and I need to figure out how to get it to look for for a file in a specific location and then if not there copy it? Also how do I run system shell commands via the xcode C++?
Got a tip for us?

macOS File Handling?

Use the C standard library. For file handling fopen() etc, and for running shell commands either system() or popen().
This might sound sarcastic but it isn't - try typing fopen in Google. You'll soon pick up on trail of the information you need.

I do appreciate, it has been a very long time since I have messed with C++. I have been using Perl mostly and the last time I used C++ was in college 8 years ago. I know it can be taken negatively, however I had no idea what to Google. File Handling comes up with some major weird stuff at first.
I do appreciate everything you have given me today as I am having to learn more advanced stuff for work (we are migrating to C++ from Perl although we will never stop using Perl
so I am not out of a job yet lol ).
I have two last questions, for now.
The first is about setting a value of checkboxes to an array. What I am thinking is something like this:
where hitting the next button would check to see if every checkbox is click or not, then pop up the next window and display the list of the printers in the array. The question is do I have the correct format and is this the best way?
The next question, I would still just use a standard text cell to display the list to confirm?
Thank you again in advance for your patience for my ignorance and for your advice and help.

printerarray[i] = Printer1;

the other 17 checkboxes

I wouldn't call it "stuck", since the C API is simple, fast, portable and accessible from C, C++, and Objective C alike.
Actually, since this is C++, the OP should, for consistency, be using standard IOStreams classes (ifstream, ofstream, etc.) for file I/O.
You're right, stuck isn't the right word, and ifstreams and ofstreams are relatively easy to work with. cppreference.com is a great place to find info on C++ coding.
This is what I have in the script. However the interface building will only let me have one Sent action for the button though and it seems that the sent action is the only thing that is executed.
Code:
- (IBAction)NextButton:(ID)sender {
[prnSelector performClose:self];
[prnOverview orderFront:self];
}
