| Mistake | Consequence | |---------|-------------| | Missing #include <unistd.h> for write | Compilation error (unless you declared it manually, but just include it) | | main returns void | Compilation error | | Infinite loop hidden by edge case | Timeout or wrong output | | Forgetting int return type for ft_strlen | Compilation error | | Using printf instead of write | Not allowed (except if subject explicitly says so in some exams – unlikely here) | | Off‑by‑one errors in loops | Wrong output, partial points possible but better to avoid | Exam 01 Piscine 42
