Flowchart to code

Questions 1 to 5 of 6

1. 1. Match each flowchart step of the even counter to the Python line that carries it out.

   Choose the matching item for each row.

   Step 2: set count to 0Choose…Line 5: count = count + 1Line 7: print(count)Line 2: number = int(input())Line 1: count = 0Step 3: read a numberChoose…Line 5: count = count + 1Line 7: print(count)Line 2: number = int(input())Line 1: count = 0Step 6: add 1 to countChoose…Line 5: count = count + 1Line 7: print(count)Line 2: number = int(input())Line 1: count = 0Step 8: print countChoose…Line 5: count = count + 1Line 7: print(count)Line 2: number = int(input())Line 1: count = 0
2. 2. Match each language to the way it reads one whole number from the user.

   Choose the matching item for each row.

3. 3. What does this program print? ``python def count_even(numbers): count = 0 for number in numbers: if number % 2 == 0: count = count + 1 return count print(count_even([3, -2, 5, 8, 6])) ``

4. 4. A student writes this C++ loop. The input file holds 4, then 6, then the end of the file, with no 0. Why does the program never stop? ``cpp int count = 0; int number; std::cin >> number; while (number != 0) { if (number % 2 == 0) { count = count + 1; } std::cin >> number; } ``

   The if test is wrong, so count never reaches 2When the read fails, number keeps its last value, 6, so number != 0 stays true and the loop never endscount is an int, so it overflows and the loop starts again from 0The std::endl line is missing, so the program waits for a newline
5. 5. In all three versions of the even counter, the line that carries out flowchart step 4 (is the number 0?) starts with the word ___.
