Basic Input & Output in Programs

In the Wolfram System's standard notebook interface, you are directly giving input and getting output every time you press Shift+Enter. Although much more rarely needed than in more primitive languages, the Wolfram Language also allows you to get input and generate output as side effects in a computation.
