handling command-line arguments (argc/argv)

Exam 01 of the 42 Piscine typically focuses on and building upon basics like loops and logic. Because the exam system is randomized for every student, there is no single "paper," but rather a set of potential problems across different difficulty levels. 📋 Exam Structure & Logistics Duration : Usually 4 hours.

Fail

If you solve Ex00 (10 pts) and Ex01 (20 pts) perfectly, you achieve 30/40. That might be a if the passing grade is 50. You need at least 50 points, meaning you must solve Ex00 + Ex02 (10+30=40, still fail) or Ex01 + Ex02 (20+30=50 = pass). Exam 01 Piscine 42

3. Unused Variables: The Norm forbids unused variables. Remove them.
4. Segfaults: If your program crashes, the grader stops. Always check for NULL returns from malloc.
5. Leaks (Experimental): Some exams now have a memory leak checker. If you malloc and don't free, you might pass functionality but fail the "Leak" test.
