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
Write one line of pseudocode that converts the string stored in heightInput into a real number and stores it in a variable called height.
3
Producing Robust Programs
Explain why iterative testing, carried out throughout development, tends to make errors cheaper to fix than relying only on final testing.
4
Boolean Logic
Complete: NOT 0 = ?
5
Data Representation: Number Systems
Convert the denary number 45 to hexadecimal.
