Read and alter existing code involving events influenced by a defined count and/or sub-program and other control structures, and describe the effect of changes on outcomes and efficiency
10 tutor-authored questions for this Ontario curriculum expectation, ordered easiest to hardest — every one with a full worked solution. Work through them free, no account needed.
Sample: the first question, solved
A sub-program is called inside a loop running 10 times. What happens if you change the loop count to 20?
📘 Worked solution
✓The sub-program will be called 20 times instead of 10, doubling the executions.
And one from the hard end
Compare a defined-count loop (exactly 10 times) to a conditional loop that might run a variable number of times. Which is more predictable?
