What is c-exam-practice-1337-42?

This repository is a personal study collection of C programming exercises, built by a student preparing for the entry tests and final exam at 42 and 1337, coding schools known for their intensive, project-based curriculum with no traditional teachers. It is meant as a practice archive rather than a finished piece of software. Each exercise sits in its own folder, named after the task it solves, and includes both the author's C code and, where available, the original exercise instructions. There are more than forty exercises in total, grouped loosely around a handful of common exam topics: working with strings, such as reversing text, changing capitalization, or applying ROT13 encoding, memory tasks like dynamic allocation and converting numbers to strings, pointer and array manipulation, small algorithms such as checking for prime numbers or counting words, and programs that read and validate command line arguments. The README gives simple instructions for compiling any single exercise using the standard C compiler with strict warning flags, then running the resulting program directly from the command line. It also describes a recommended way to use the repository: read the original exercise description first, try to solve it independently, compile and test it carefully, including edge cases, and only afterward compare your own solution against the one provided here. The author is explicit that these are personal solutions, that exercise wording can vary between different 42 or 1337 campuses, and that the repository is meant to support learning rather than replace the work of solving each exercise yourself. It is aimed at other students on the same or similar curriculum who want reference solutions and practice material for the same style of C exam questions.
