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!

This is a screen print of the editor. The CeeBot key words of the programming language are highlighted. Identation is automatic. As soon as you type an instruction, a summary of the syntax appears at the bottom of the screen. If necessary, you can call up a complete help text just by clicking an icon.
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.
