Section 2.2: Compiling and Running

Depending on your computer and your compiler, the process of compiling your program varies. For now, we'll assume that you are using a UNIX machine and the gcc compiler. Gcc is a free compiler which is available on virtually all UNIX systems.

To compile your program, type the following command at a UNIX prompt: 

g++ hello.C -o hello
Make sure that g++ is in your path and that you are running it in the directory containing hello.C.

Congratulations - you've just compiled your first C++ program! The program is called hello and is located in the same directory containing the file hello.C. To run your program, simply type hello at your UNIX prompt. You should see the following output: 

# hello
Hello, World!
#
That's all there is to it!
