42Piscine

This repository contains all the projects I completed during my participation in the C Piscine at the Malaga campus from 17 October to 11 November 2022.

🏊‍♂️ About 42

42 is a global education initiative that proposes a new way of learning technology based on the following principles:

• No courses. No teachers. No classes.
• A project method.
• Failing is progressing.
• Peer-to-peer learning.
• Peer-to-peer evaluation.
• Group work is not cheating.

The 42 cursus is free for whoever is approved in its selection process. The so-called "C Piscine", a 26-day C programming bootcamp, is the last stage in the selection process for becoming a "cadet" (42's student).

During the Piscine, I learned C Language (It is the main program used for both projects and exams), Shell (The first two days are dedicated to learning the necessary commands to be able to navigate through the MAC terminal) and Git (All projects are submitted via a remote git repository).
