• ft_isascii: Check if a character is a valid ASCII character.
• ft_isprint: Check if a character is a printable character.

• ft_strlen: Calculate the length of a string.
• ft_strcmp: Compare two strings up to a specified number of characters.
• ft_strncmp: Compare two strings up to a specified number of characters by given bytes.
• ft_toupper: Convert a character to uppercase.
• ft_tolower: Convert a character to lowercase.
• ft_strchr: Locate the first occurrence of a character in a string.

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

1. Clone the libft repository to your local machine.
2. Compile the library by running make in the libft directory. This will generate the libft.a archive file.
3. Include the libft.h header file in your source files: #include "libft.h".
4. Link your program with the libft.a archive during the compilation process. For example: gcc main.c -L/path/to/libft -lft -o myprogram.
