Xcode question

[John Does]

Could you tell me where to place the input file in xcode? It builds and runs the program, but it only shows the functions that are outf. So, I think it's not seeing the input file, and I know the program works the way I intended, because it outputs perfectly fine via the terminal. I just don't see any numbers. Here is how it should look

That is via the terminal with g++.

Here is what xcode gives me.
