Libft

Libft is the first 42 School Common Core project. The objective of this project is to develop a library of utility functions written in C that provide commonly used functionalities. For didactic purposes, my primary focus was on achieving maximum optimization. However, I also took into consideration the importance of maintaining easy understanding, even if it meant sacrificing some optimization in certain functions.

Features

• Standard Library Functions: memset, memcpy, strlen, strcpy, and more.
• Linked List Manipulation: Functions to create, add, remove, and iterate through linked lists.
• String Manipulation: Functions to manipulate strings, such as strdup, strjoin, and strtrim.
• Character Manipulation: Functions to check character types, convert cases, and perform other character-related operations.
• Memory Management: Functions for dynamic memory allocation and deallocation, such as malloc, free, and realloc.
• Additional Functions: Various useful functions, including mathematical operations, file handling, and more.

Getting Started

To use the libft library in your C project, follow these steps:

1. Clone the repository: git clone https://github.com/codemarc42/libft.git
2. Include the libft.h header file in your source code: #include "libft.h"
3. Compile your project with the libft.a static library: gcc -Wall -Wextra -Werror -L./libft -lft -o your_name_program your_source_files.c

Usage

Here's a simple example of using a function from libft to count the number of characters in a string:

#include "libft.h"
#include <stdio.h>

int main(void) {
    const char *str = "Hello, world!";
    int length = ft_strlen(str);
    printf("Length of the string: %d\n", length);
    return 0;
}
