1
1D and 2D Array Processing: Writing and Tracing Programs
Trace this algorithm with data = [4, 9, 2, 9, 7] and state the final output. total = 0; count = 0; for i = 0 to 4: if data[i] > 5 then total = total + data[i] and count = count + 1; next i; print(total, count).
2

Given x = 5 and y = 8, state whether x < y AND x > 0 evaluates to True or False.
3
Producing Robust Programs
State what is meant by a syntax error.
4
Boolean Logic
State the two values a Boolean data type can hold.
5
