Hello World

One of the best ways to learn how to program in a new language is by looking at lots and lots of example programs. The best thing to do is to copy and paste each program below into a text file and compile it. Then, try the experiments. By extending these example programs, you will gain familiarity with different aspects fo C++, and you will feel more confident when it comes time to write programs from scratch.
