[newbie] C++ Compiler Help

[ChOPpY C. Chipper]

hey, this is an easy question: How do I compile a program under g++ I just can't figure it out lets say, I have a file called "test.cpp" under / the dir how would I compile it? when i try, it does not return anything on the command line and just makes a new command line, just like when i started! also, do all the compilers work the same way? ie - gcc, etc.   Thanks, Julien
