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
Programming Fundamentals
State the most appropriate data type for storing a person's shoe size if only whole sizes (e.g. 7, 8, 9) are allowed.
3
Producing Robust Programs
A password field requires between 6 and 12 characters. State two boundary data values that should be used to test this field.
4
Boolean Logic
Given P = 0 and Q = 1, state the value of P OR Q.
5
