Libft

Overview

Libft is the inaugural project of the Common Core curriculum, designed to create a robust and tested library of essential C functions. Rigorous testing is essential as this library will serve as a foundation for future projects. The code is intended to be correct, concise, and easily understandable for maintenance and expansion.
