Question

How many values will be input into the array Songs based on the pseudocode below: Begin For I ← 0 to 5
Input Song Songs(I) ← Song Next End

A for-loop that runs from 0 to 5 executes once for each integer in that inclusive range. Key points: array indexing often starts at 0, loop bounds are inclusive as written, and the number of iterations of an inclusive integer range is (last − first + 1).

Step-by-step reasoning:
1. The loop header is For I ← 0 to 5. That means I takes the values 0, 1, 2, 3, 4, and 5 in sequence.
2. On each iteration the code reads an input Song and stores it in Songs(I). So one value is stored per iteration.
3. Count the iterations explicitly: I = 0 → Songs(0) filled; I = 1 → Songs(1); I = 2 → Songs(2); I = 3 → Songs(3); I = 4 → Songs(4); I = 5 → Songs(5).
4. Total iterations = number of integers from 0 to 5 = 5 − 0 + 1 = 6.

Why the correct answer is correct:
- The loop runs 6 times, storing one song each time, so 6 values are input into the Songs array.

Why the other choices are incorrect:
- a. 1 is wrong because the loop clearly repeats multiple times, not just a single input.
- b. 5 is wrong because that would be the count if the loop ran from 1 to 5 (or 0 to 4). Here it runs from 0 through 5, which adds one more iteration.
- c. 0 is wrong because the loop body executes; values are being input and stored.

Conclusion: The correct number of values input into the Songs array is 6, matching answer d. 6.
