libft

libft is a C library project that aims to recreate some of the C standard library functions, as well as additional utility functions commonly used in programming. This project is part of the 42 coding school curriculum and helps students solidify their understanding of C programming, memory management, and data structures.

Features

• String manipulation functions, such as ft_strdup, ft_strjoin, ft_strncmp, and ft_strtrim.
• Memory management functions, such as ft_memset, ft_memcpy, ft_memmove, and ft_memcmp.
• Linked list data structure implementation with functions for creation, modification, and traversal.
• Integer manipulation functions, such as ft_itoa, ft_atoi, and ft_isdigit.
• File descriptor manipulation functions, such as ft_putchar_fd, ft_putstr_fd, ft_putendl_fd, and ft_putnbr_fd.

Getting Started

Prerequisites

• A Unix-based operating system (macOS, Linux, or WSL on Windows)
• GCC compiler
• make utility

Installation

1. Clone the repository:

git clone https://github.com/JosephKiragu/libft.git

2. Change into the project directory:

cd libft

3. Compile the project using the provided Makefile:

make

Usage

1. Include the header file libft.h in your C source files where you want to use the libft functions.

#include "libft.h"

2. Use the libft functions in your code. Here's an example:

#include "libft.h"

int main(void)
{
    char *src = "Hello, World!";
    char *dst;

    dst = ft_strdup(src);
    ft_putstr(dst);
    ft_putchar('\n');

    free(dst);
    return 0;
}

3. Compile your program with the libft object files:

gcc -Wall -Wextra -Werror -I./ -o your_program your_program.c libft.a

4. Run your program:

./your_program

Testing

The project comes with a test suite. To run the tests, follow these steps:

1. Compile the test program:

make test

2. Run the test program:

./test_libft
