ITPEC IP April 2025 Question 7
ITPEC IP April 2025 — Question 7 of 100
Option (d) supplies the required condition and outputs — use the even/even test, output i when true, and output "+" otherwise.
For even outer-loop values i = 0, 2, 4, 6, the output shows i at even inner-loop positions j = 0, 2, 4, 6 and plus signs at odd positions. For odd i, the conjunction is false for every j, producing seven plus signs. Thus A is (i mod 2 = 0) and (j mod 2 = 0), B is i, and C is "+".
Answer (d)
Why not others: (a) and (b) test odd/odd positions, contradicting the digit positions. (c) uses the right condition but swaps the two outputs.
Key rule: Trace both loop indices: a conjunction runs its true branch only where both independent conditions hold.
