📚 Libft – Custom Standard C Library

Welcome to Libft, a personalized implementation of the standard C library featuring over 40 common functions! 🎉 This library focuses on memory management, string manipulation, and linked list operations. 🚀

📝 Project Overview

Libft aims to enhance your programming skills by providing a rich set of functions that are often needed in C programming. From memory allocation to string handling and linked lists, this library covers a broad spectrum of functionalities that are essential for various applications.

Key Features:

• 🔹 Memory Management: Functions for allocating and managing memory.
• 🔹 String Manipulation: Operations for handling strings, including conversions and searches.
• 🔹 Linked Lists: Comprehensive support for linked list operations.

📦 Installation & Setup

To get started with Libft, follow these simple steps:

1. Clone the repository:

   git clone https://github.com/mdev9/libft.git
   cd libft

2. Build the project:

   make

🛠️ How to Use Libft in Your Code

To use the functions from Libft in your C programs, include the header file at the top of your source files:

#include "libft.h"

Example Usage:

Here’s a simple example demonstrating how to use a few functions from the library:

#include "libft.h"

int main() {
 char *str = "Hello, World!";
 char *dup = ft_strdup(str); // Duplicate the string
 int len = ft_strlen(dup);    // Get the length of the duplicated string

 printf("Original: %s\n", str);
 printf("Duplicate: %s\n", dup);
 printf("Length: %d\n", len);

 free(dup); // Remember to free allocated memory!
 return 0;
}

ft_lstsize_bonus	Counts the number of elements in a linked list.
ft_memchr	Searches for a character in a memory block.
ft_memcmp	Compares two memory blocks.
ft_memcpy	Copies memory area from source to destination.
ft_memmove	Moves memory area from source to destination safely.
ft_memset	Fills a memory area with a specified value.
ft_printf	Custom implementation of printf for formatted output.
ft_putchar_fd	Outputs a character to a given file descriptor.
ft_putendl_fd	Outputs a string to a given file descriptor followed by a newline.
ft_putnbr_fd	Outputs an integer to a given file descriptor.
ft_putstr_fd	Outputs a string to a given file descriptor.
ft_split	Splits a string into an array of substrings based on a delimiter.
ft_strchr	Locates the first occurrence of a character in a string.
ft_strdup	Duplicates a string by allocating sufficient memory.
ft_striteri	Applies a function to each character of a string, passing the index as an argument.
ft_strjoin	Joins two strings into a new string.
ft_strlcat	Concatenates two strings while limiting the total length.
ft_strlcpy	Copies a string with size limit to prevent overflow.

ft_strncmp	Compares two strings up to n characters.
ft_strnstr	Locates a substring in a string, searching only the first n characters.
ft_strrchr	Locates the last occurrence of a character in a string.
ft_strtrim	Trims specified characters from the beginning and end of a string.
ft_substr	Creates a substring from a string.
ft_tolower	Converts a character to lowercase.
ft_toupper	Converts a character to uppercase.
get_next_line	Reads a line from a file descriptor, managing buffer allocation.
