Run norminette on every .c and .h file. Fix every error. Then, sleep well. The exam requires mental clarity.
Unlike Rank 02 (which focused on static functions), Rank 03 is all about interaction with the system. 42 Exam Rank 03
You will face two exercises, but you only need to ace one to validate. However, there is a strategic catch: Run norminette on every

While the exam code itself is written in a single file, understanding how libraries work is crucial for the testing environment. Students often need to compile their code with specific flags (like -Wall -Wextra -Werror). Furthermore, the exam often allows the use of previously written functions (like ft_strlen or ft_putchar), provided they are linked correctly.
