$ gcc input.c -o output
Hello World in C!
$ g++ input.cc -o output
Hello World in C++!
The '$' is the prompt, the "Hello World" lines are example outputs..
You (usually) need to add the './' to the command in order for it to run from
the current directory -- that is because the current directory is not in the
PATH (as opposed to in DOS, where if you type in a command, it looks in the
current directory before looking elsewhere..)

The 'man' command is your friend, learn it, know it, use it..
Also, for any documentation, poke around in the /usr/doc directory or search
around on the Internet..
