Try it yourself: Debug a sandwich robot
- Write step-by-step instructions for making a pretend sandwich, using two books as the bread.
- Your robot must do exactly what the words say, nothing more. "Put jam on bread" might mean the jar goes on the bread!
- Every time something goes wrong, that is a bug. Fix that line and run it again.
- How many fixes did it take until the robot got it right first time?
Computers follow instructions literally, so writing clear steps and fixing bugs is a big part of a programmer's work.
