42exam Github Access

I'll create a complete write-up for a GitHub repository named "42exam". Assumptions: it's a coding project for the 42 school exam (C/Unix projects). I will produce a README with project description, requirements, installation, usage, testing, structure, coding guidelines, common pitfalls, and example solutions. If you'd like different language/framework or specific project details, tell me—otherwise I'll proceed with the generic 42 exam C project template.
