Strategy & Tips

  • Start with guaranteed points – Do 2–4 point exercises first (e.g., ft_strlen, ft_swap).
  • Prototype accuracy – Missing const or wrong return type fails the whole exercise.
  • Handle edge cases – NULL strings, n = 0, INT_MIN in ft_putnbr.
  • No memory leaks – malloc must have a matching free (test with ft_range).
  • Keep functions static‑gradeable – No global variables, no extra includes.
  • Practice recursion – Many students lose time re‑inventing factorial / square root logic.

The key difference between Exam 00 and Exam 01 is autonomy. In Exam 00, you can pass by memorizing a few patterns. In Exam 01, the exercises require you to think in pointers and manage memory manually. If you don’t understand how a stack and heap work, Exam 01 will feel like an impossible puzzle. c piscine exam 01

Example:

A Sample 4-Hour Strategy for Exam Day

  • Hour 1 (Level 00): Complete Level 00 in 15 minutes. Double-check Norminette. Commit and push. Unlock Level 01.
  • Hour 2 (Level 01): If Level 01 asks for ft_strdup, write it carefully. Test with valgrind (if available) or manually. Move to Level 02.
  • Hour 3 (Level 02): This is the decider. If you see ft_atoi_base, write the auxiliary function get_base_index. If you see ft_split, implement count_words first. Do not rush.
  • Hour 4 (Level 03): Only attempt if Level 01 and 02 are 100% correct. Use the last hour to polish. If stuck, go back and improve earlier answers (they can be re-submitted).
