My first c library

Libft

Score

The "libft" project is a fundamental exercise in C programming, requiring to create a custom C library containing essential functions. Divided into mandatory and bonus parts, the project fostering a deep understanding of foundational concepts like memory allocation and string manipulation. Adherence to coding standards, such as the Norm standard and proper memory management practices, is emphasized throughout the project. The bonus part introduces tasks related to manipulating linked lists, further enhancing proficiency in data structures and algorithms.
