Using GCC via Xcode to Compile Base Programs
So, I'm a new CS student, on Mac, and I'm learning C ++ for one of my classes. And I have a dumb question about how to compile my super main C ++ program.
I installed Xcode, and I am going through the documentation to try and figure out how to use it (and I very much suspect that this has hugely affected what I am doing now) and eventually ends up in Terminal and going to "gcc [filename ] ". And I have a screen with text that starts with "Undefined Symbols" and keeps trying to reference things, so I wonder if I have connected something somewhere, especially when I'm actually in Xcode with an open program in C ++ most menu items are greyed out.
So. In really really basic terms. What am I missing and how do I fix it? Is there a basic tutorial for Xcode? Most of the documentation is for real developers, and I'm completely missing a lot of what's supposed to be done.

If Xcode is installed everything is set up correctly.
If you typed gcc on the command line, you were calling the 'C' compiler (not the C ++ compiler). This usually doesn't matter as GCC compensates by looking at the file extension. But what matters is that it doesn't call the linker with the correct C ++ flags.
What you have to do (from command line) use g ++
g++ <fileName>.cpp
By default, the output file is a.out and is placed in the same directory.
g ++ has a flag to specify a different output name -o
g++ -o <outputName> <fileName>.cpp
