// Doing it again

REPEAT UNTIL

Some loops don't know how many times. They just go UNTIL something happens. Read this:

REPEAT UNTIL the cup is full:
    pour 1 spoon of water

Circle the answer

If the cup holds 8 spoons, how many times does this loop run?

(a) 1 (b) 8 (c) Forever

My answer:
WHY THIS EXERCISEREPEAT UNTIL exits when its condition becomes true. Loops that don't have a stopping condition are bugs.

Now write a REPEAT UNTIL loop for filling a backpack with books until it is heavy.
