![]() | Section 2: A First Program |
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 helloMake 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!
