## What it is
A comprehensive cheat sheet and guide covering strict C programming, tailored for 42 School students, alumni, and candidates. It documents C fundamentals, common beginner mistakes, 42 project guides, and advanced topics like SIMD, SDL2, and bitwise operations.

## Use cases
- learn strict C programming from scratch
- prepare for the 42 School Piscine entrance exam
- understand common C beginner mistakes like segmentation faults and memory leaks
- find guides for 42 School curriculum projects
- review pointers, data types, and bitwise operations in C
- work around the 42 norminette coding style rules

## When to choose
- you are a 42 School student, candidate, or alumnus working through the C curriculum
- you want a curated reference of C pitfalls and idioms in one document
- you need guidance on 42-specific projects and the norminette style checker

## When to avoid
- you need a formal C textbook or standards reference rather than a school-specific guide
- you are not working in C or with the 42 School curriculum
- you need runnable software or a library rather than documentation
