Instructions

Each exercise begins with precise instructions, often completed with an illustration. The goals and main programming principles are explained. Sometimes the program is developped completely with an explanation for each line, sometimes you are given a few clues to help you write the program yourself. But a solution is always at hand. You'll never be stranded in the middle of nowhere!

Spelling mistakes are immediately pointed out.
You can use a step-by-step debugger that executes your program showing all the variables in real-time.
