A script has the following code: x = 1; def increment(): x = x + 1; increment(); print(x). The script prints 1 instead of 2. What is the most likely cause?

The print statement is executed before the function call

The variable x inside the function is local, so the global x is not modified

The increment operation is a syntax error

A C developer is writing a program that allocates memory for a structure, uses it, and then frees it. The program runs correctly most of the time but occasionally crashes. The code uses `malloc()` and `free()`. Which of the following is the most likely cause of the intermittent crash?

The program uses the memory after freeing it.

The program frees the memory twice.

The program does not check if `malloc()` returns NULL.

The program uses `calloc()` instead of `malloc()`.

A developer is writing a Python script to validate user input. The script should accept a string if it is not empty and its length is less than 10. The developer writes: if len(user_input) < 10 and user_input != '':. This works, but the developer wants to avoid a potential error if user_input is None. Which condition is the safest?

if user_input != '' and len(user_input) < 10:

if len(user_input) < 10 and user_input is not None and user_input != '':

if len(user_input) < 10 or user_input != '':

if user_input is not None and len(user_input) < 10 and user_input != '':

A developer is writing a Python script that reads a CSV file and sums the values in the second column. The code is: `total = 0; with open('data.csv') as f: for line in f: parts = line.split(','); total += int(parts[1])`. The script raises a `ValueError` on the first line. What is the most likely cause?

The file uses semicolons as delimiters instead of commas.

The script does not close the file.

The first line is a header row that contains non-numeric text.

Part of the Programming and Logic domain, which makes up ~12% of our current practice bank. GIAC (SANS) does not publish an official question count, but from its 120-minute exam (~50–80 total, ~6–10 in this domain), expect 6–10 from this objective — we provide 40 practice questions to prepare you well beyond it.
