Libft

This project was completed as part of the curriculum at École 42. The goal of the project is to create a library of useful functions that can be used in future projects.

Installation

To use the libft library, follow these steps:

1. Clone the repository to your local machine.
2. Open a terminal window and navigate to the root directory of the project.
3. Run the command make to compile the library.
4. Include the header file libft.h in your project.
5. Link the library during compilation using the -L and -l flags.

gcc -o my_program my_program.c -L/path/to/libft -lft

Usage

The libft library provides a wide range of functions that can be used for string manipulation, memory management, character checks, linked lists, and more. The functions are prefixed with the ft_ abbreviation.

To use a specific function, include the corresponding header file and call the function in your code. Here's a new example that demonstrates the use of different functions:

#include "libft.h"

int main(void) {
    char src[] = "Hello,";
    char dest[20];
    
    ft_strcpy(dest, src);
    printf("Copied string: \"%s\"\n", dest);
    
    char str[] = "Hello, world!";
    int length = ft_strlen(str);
    printf("Length of string: %d\n", length);

    int is_alpha = ft_isalpha('A');
    printf("Is 'A' alphabetic? %d\n", is_alpha);
    
    int is_digit = ft_isdigit('9');
    printf("Is '9' a digit? %d\n", is_digit);
    
    return 0;
}

In this example, the program demonstrates the use of different functions. It copies a string using ft_strcpy, calculates the length of a string using ft_strlen, and checks if a character is alphabetic using ft_isalpha and if a character is a digit using ft_isdigit. The results are then printed to the console.

Make sure to compile your program with the libft library, as mentioned in the installation instructions.

Documentation

For detailed documentation on all available functions in the libft library, refer to the libft.h header file. Each function is documented with its parameters, return value, and a brief description of its purpose.
