To pass, your code must adhere to strict C++98 standards (unless your campus specifies otherwise) and focus on:
Here is a comprehensive guide to preparing for and passing Exam 05. 42 exam 05

| Pitfall | Solution | | :--- | :--- | | "My program works 90% of the time, but fails randomly." | That's a race condition. Add mutexes around EVERY shared variable access. | | "I get a deadlock after two minutes." | You forgot to unlock a mutex in one error path. Use pthread_mutex_unlock before every return or exit . | | "Moulinette says 'Segmentation fault' but my local machine runs fine." | You probably used a library function not allowed ( printf inside a signal handler? No). Or you failed to initialize a semaphore pointer. | | "I passed the first two exercises, but the third is impossible." | Strategy: Get partial points. If you cannot solve the full producer-consumer, at least initialize all semaphores and create the threads. Moulinette grades per test case. | Add mutexes around EVERY shared variable access
She closed her laptop, walked out into the wet cobblestone street, and for the first time in two weeks, called her mother.
Here is the strategy I used to finally pass:
typically falls after Circle 04 (or early Circle 05, depending on the campus version). While the earlier exams focused on libft, recursion, and simple data structures, Exam 05 dives headfirst into multithreading, process synchronization, and inter-process communication .
