Answer Key
Pseudocode for presenting results
Section A: Quick Questions
Q1
B — print "Total: " + total
Q2
B — One record per line, printed inside a loop
Q3
A — Before the loop, so it prints once
Q4
A — for i from 1 to 5
print names[i]
next i
print "Total: " + total
Q5
A — print "Mark: " + mark
Section B: Match the Pairs
Q1
print "Total: " + total → Shows a label followed by the value of total, so the result is easy to read
Q2
print "=== Class Report ===" → Prints a heading line at the top of a report
Q3
Print one record per line by putting the print statement inside a loop → for i from 1 to 5
print names[i] + ": " + marks[i]
next i
Q4
Print the total once after the loop, so it appears at the end of the report → for i from 1 to 5
total <- total + marks[i]
next i
print "Total: " + total
Q5
print "Total: " total → The + joining the label and the variable is missing, so the label and value are not combined into one output
Q6
for i from 1 to 5
print "Report"
print names[i] + ": " + marks[i]
next i → The heading is printed inside the loop, so it repeats before every record instead of appearing once
Section C: Definitions
Q1
print "Total: " + total — A print statement that joins a label to a value so results are readable. Use headings, labels and one record per line, often inside a loop, to build a report.Section D: Fill in the Blanks

end forSection E: Spot the Error
Q1
B — The label and the variable are not joined. A + is needed between them: print "Name: " + name.
Q2
A — Pseudocode uses the print keyword to display a heading. It should be print "=== Sales Report ===".
Q3
C — The age index is fixed at 1, so every line would show the first age. It should use the loop counter: age[i].
Q4
C — This overwrites total each time round the loop instead of adding to it. It should be total <- total + mark[i], so the final total is correct.
Q5
B — The loop header is missing the keyword to. It should be for i from 1 to 3, so one record is printed per pass.
