This is what I got when I typed in that code.

-rw-r--r-- 1 Gav staff 93 20 Jan 18:38 myHello.cThat inconsistency with program1 and practical1 was just a mistype... the name of the file that I want to run is practical1.cpp
Code:
cd Desktop
Code:
cd ~/DesktopEDIT: One way to make sure the file you want is in the current working directory is to use tab completion from the shell.
i.e.
Code:
make p<TAB>keep hitting TAB until the name of the file you want shows up.

I LOVE YOU! No Homo!
I forgot one of the steps that we were told in college and that was to change where the program was going to save from desktop to USERNAME
PROBLEM SOLVED
For all who care here is my fist program on my MBP
Code:
Gavin-McGuinnesss-MacBook-Pro:~ Gav$ make practical1
make: `practical1' is up to date.
Gavin-McGuinnesss-MacBook-Pro:~ Gav$ ./practical1
My first C++ program.
The sum of 2 and 3 = 5
7 + 8 = 15
Num = 6
Glad you got it going, Gavin! (Hey, that's alliteration!)
I suggest that you get yourself familiar with the Terminal (unix shell). You should have be comfortable enough that navigating to different directories, and doing basic file operations like copying, moving, renaming and deleting files should become second nature. You'll be doing a lot of it if you continue to learn how to do programming from a command-line environment.
It's also really good experience. Understanding Unix is a marketable skill that you can put on your resume, and it's one that has lasting value. It was useful back in the 70's and it's still useful today.
Become completely familiar with the following Unix commands:
cd (including the "~", "." and ".." directories)
ls (and its variants, ls -a, ls -l, etc.)
cat
cp
mv
pwd
echo
And your favourite text editor, be it TextEdit, or a Unix one like emacs, pico
And then of course your compiler tools:
make
g++
gdb (eventually)

Ok I moved my project to a sub folder in my documents, How do I run that without having to move it back to the "Username" section?

Thanks... Is it weird that I am really excited to get stuck into some work?
Hah yes well I am doing a general engineering degree at the moment and in my 3rd year I chose a topic to specialise in... looking forward to learning more about computer engineering and software engineering in the years to come.
OS X actually makes that pretty easy.
In Terminal, type
Code:
cd<SPACE>EDIT: or manually just
Code:
cd ~/Documents/SubfolderAs notjustjay suggests, mess around with some basic unix commands and get comfortable with them.

* I've done this and it works just fine!
Now one more question... Now that I have change my directory will it stay as that folder until I change it myself.
As I said I am really looking forward to learning more about terminal and coding.
Ok thank you again.
It has been a pleasure. If there was a rating feature on this you my friend would get a 5/5

Remember in Jurassic Park there's a scene in which the girl looks at a computer displaying some sort of 3-D overhead-flying render of the file system and she says "Hey, this is Unix! I know this!"
It's a silly scene, but maybe it can help with the Terminal frame of mind. With a desktop metaphor like OS X or Windows, you can have multiple folder windows open at once. When in a Terminal window, think of it like YOU are standing in one particular spot in your file system. You stay there until you move yourself. You can move yourself downward into another directory or back upward to the place you came from before. Like a little adventure game...
Every time you start a new Terminal, you're placed in the same folder, your "home" directory, like an adventure game placing you at the beginning of a level.
Hope that's helpful somehow
Ahh, that brings back some memories. That was actually a real file manager that ran under IRIX. They actually have a clone that will run under OSX

You said you saved practical1.cpp from Smultron on your Desktop. Terminal doesn't start in your Desktop, it starts one step higher in your home directory.
Try:
cd Desktop
make pratical1
And see what you get. Make will complain if it has no Makefile AND it can't find a source file that matches its "default" behavior mentioned earlier.
For future reference, run:
pwd
to see your working directory. If it's not where you think it should be, you'll need to move around with cd.

EDIT: Oops. I read to the bottom of page 1 and was replying based on that. Oh well, you got it going, good times.

I now know where to come when I hit my next stumbling block!
