Section 1

First steps: values, variables and your first programs

What programming is and how a computer runs your code, one line at a time. You will print messages, meet numbers, text and true-or-false values, store them in variables, do arithmetic, glue text together, write comments and learn to read error messages calmly. The lab ties it together in a receipt printer.
