primary chapter**, where most of the needed material is taught. List others only if
the question genuinely needs them.
- `difficulty`: 1 (direct application), 2 (combines ideas), 3 (exam-hard or longer).
- `level` (exam questions only, required there): where the question sits on the 1-4 exam
scale. The question's position in the exam is a strong hint, but its content decides.
`tools/gen-exercises.py` lists every exam question by level in `questions/exam-questions.md`.
1. **Short question, not a whole program:** explain or trace given code (what it prints,
what a function does), a type, operator or memory question, or a short fragment or
function. Usually the first θέματα.
2. **Simple complete program with input:** a whole program that reads its data from
stdin or argv and does simple processing on it, with one loop or a simple double loop.
Usually Θέμα 3.
3. **Data structures and dynamic memory:** a program built around a data structure
(linked lists, trees, ...) with heap allocation (`malloc`/`free`) and the pointer
handling that goes with it.
4. **The hardest θέμα:** usually the last one. Larger programs that may combine the above
with file handling or need dynamic programming or another non-obvious algorithm.
- `type` is one of:
- `programming`: write a program or function
- `short-answer`: explain or define

(Kahoot), και ένα μόνιμο αναγνωριστικό, π.χ. `exam-2025-jan-q2`. Ο αριθμός
ακολουθεί την τρέχουσα έκδοση του οδηγού· το αναγνωριστικό δεν αλλάζει ποτέ.

Τα θέματα εξετάσεων, ταξινομημένα σε τέσσερα επίπεδα δυσκολίας, είναι και στη σελίδα
[Θέματα εξετάσεων](exam-questions.md).

Σε μορφή για εργαλεία: [`questions.json`](https://progintro.github.io/study/downloads/questions.json).

Στα θέματα της online εξέτασης Δεκεμβρίου 2023 (`exam-2023-fall-*`) ισχύει για όλες τις ασκήσεις: τα προγράμματα πρέπει να είναι ευανάγνωστα, αποδοτικά σε χώρο και χρόνο και να έχουν έξοδο ίδια με τα παραδείγματα εκτέλεσης. Για είσοδο εκτός προδιαγραφών το πρόγραμμα τερματίζει με exit code 1 και μήνυμα σφάλματος.
