Introduction

Libft is a C programming project aimed at creating a custom C library containing a set of general-purpose functions. The goal is to understand and implement functions similar to those found in the standard C library (libc). This library will serve as a foundation for future C school assignments.

Common Instructions

• Language: The project must be written in C.
• Norm Compliance: Ensure that your code complies with the Norm.
• Functionality: Functions should not quit unexpectedly, and memory must be properly managed to avoid leaks.
• Makefile: Provide a Makefile with rules for compiling and cleaning the project.
• Testing: Create test programs to validate your functions.

Mandatory Part

Technical Considerations

• Declaring global variables is forbidden.
• Use static functions for helper functions.
• Place all files at the root of your repository.
• Unused files are not allowed.
• Compilation flags: -Wall -Wextra -Werror.
• Use the ar command to create your library.

Part 1 - Libc Functions

Implement libc functions with the 'ft_' prefix. Some functions include:

• isalpha
• isdigit
• strlen
• memcpy
• strchr
• atoi

Part 2 - Additional Functions

Implement custom functions such as:

• ft_substr
• ft_strjoin
• ft_strtrim
• ft_split
• ft_itoa
• and more...

Bonus Part

Expand your library to include functions for manipulating linked lists using the t_list structure.

Functions to implement include:

• ft_lstnew
• ft_lstadd_front
• ft_lstsize
• ft_lstlast
• ft_lstadd_back
• ft_lstdelone
• ft_lstclear
• ft_lstiter
• ft_lstmap
