🎯 Libft Project

Introduction

The Libft project is a foundational exercise aimed at deepening your understanding of low-level memory management and function implementation in C programming.

Grade

Objective

The objective of this project is to implement a set of standard functions commonly used in C, along with some additional functions, forming your very own Libft library. This will serve as a crucial building block for future projects that rely on custom functions and memory management.

Features

The library includes a variety of functions grouped into categories:

Functions from <ctype.h>

• ft_isalpha: Checks if a character is alphabetic.
• ft_isdigit: Checks if a character is a digit.
• ft_isalnum: Checks if a character is alphanumeric.
• ft_isascii: Checks if a character is part of the ASCII character set.
• ft_isprint: Checks if a character is printable.
• ft_toupper: Converts a character to uppercase.
• ft_tolower: Converts a character to lowercase.

Functions from <string.h>

• ft_memset: Fills a block of memory with a specified byte.
• ft_strlen: Computes the length of a string.
• ft_bzero: Sets a block of memory to zero.
• ft_memcpy: Copies memory from one location to another.
• ft_memmove: Moves memory from one location to another safely.
• ft_strlcpy: Copies a string to a specific size.
• ft_strlcat: Concatenates a string to a specific size.
• ft_strchr: Finds the first occurrence of a character in a string.
• ft_strrchr: Finds the last occurrence of a character in a string.
• ft_strncmp: Compares two strings up to a specified number of characters.
• ft_memchr: Scans memory for a specific byte.
• ft_memcmp: Compares two memory areas.
• ft_strnstr: Finds a substring within a string.
• ft_strdup: Creates a duplicate of a string.

Functions from <stdlib.h>

• ft_atoi: Converts a string to an integer.
• ft_calloc: Allocates memory and initializes it to zero.

Non-Standard Functions

• ft_substr: Extracts a substring from a given string.
• ft_strjoin: Concatenates two strings into one.
• ft_strtrim: Trims leading and trailing characters from a string.
• ft_split: Splits a string into an array of substrings based on a delimiter.
• ft_itoa: Converts an integer to a string.
• ft_strmapi: Applies a function to each character of a string.
• ft_striteri: Applies a function to each character of a string using its index.
• ft_putchar_fd: Writes a character to a file descriptor.
• ft_putstr_fd: Writes a string to a file descriptor.
• ft_putendl_fd: Writes a string followed by a newline to a file descriptor.
• ft_putnbr_fd: Writes an integer to a file descriptor.

Linked List Functions

• ft_lstnew: Creates a new linked list node.
• ft_lstadd_front: Adds a new node at the beginning of a linked list.
• ft_lstsize: Returns the number of nodes in a linked list.
• ft_lstlast: Returns the last node of a linked list.
• ft_lstadd_back: Adds a new node at the end of a linked list.
• ft_lstclear: Clears and frees a linked list.
• ft_lstiter: Applies a function to each node of a linked list.
• ft_lstmap: Applies a function to each node of a linked list and returns a new list.

Getting Started

To use the Libft library in your project:

1. Clone the repository:

   git clone https://github.com/amine-54/libft.git

2. Run make to compile the library:

   cd libft
   make

3. To clean up the compiled files, use:

   make clean

4. To fully clean up, use:

   make fclean

5. To recompile and clean everything, use:

   make re
