Project Goals

1. Provide a comprehensive set of standard functions for C development.
2. Create a library that enhances code modularity and maintainability.
3. Support a variety of operations, from string manipulation to memory management.
4. Ensure correctness and reliability through extensive testing.
5. Facilitate code reuse by offering a reusable set of functions.

Usage

1. Clone the repository

   git clone [email protected]:kbly538/libft.git
   cd libft

2. Build the Static Library

   make
   

To use the Libft library in your C projects, include the "libft.h" header file and compile your code with the compiled "libft.a" library. For example:

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

int main() {
    char str[] = "Hello, World!";
    size_t length = ft_strlen(str);
    printf("Length of the string: %zu\n", length);
    return 0;
}

Compile with:

gcc -o my_program my_program.c libft.a
