42 school's first project, libft, is about learning how the standard functions of C programming work, by coding them from scratch and creating our very own library.
Libft is a very important project, since this library will be used in future 42 school assignments. If you are a 42 student, I highly recommend you go through the trial and error process of writing your own code and testing it yourself, rather than copy-pasting code you only half-understand. If you've succeeded your piscine, there is no reason you couldn't figure this project out for yourself! Be patient and thorough.

The mandatory functions of libft are either functions from the standard C library or other useful functions. They are mostly useful for character, string and memory manipulation. These 34 mandatory functions must be done correctly to get a 100% grade.
Functions to check and manipulate characters:
- ft_isalpha
- ft_isdigit
- ft_isalnum
- ft_isascii
- ft_isprint
- ft_toupper
- ft_tolower
Functions to manipulate strings:
- ft_strlen
- ft_strlcpy
- ft_strlcat
- ft_strchr
- ft_strrchr
- ft_strncmp
- ft_strnstr
- ft_substr
- ft_strjoin
- ft_strtrim
- ft_split
- ft_strmapi
- ft_striteri
Functions to manipulate memory:
- ft_calloc
- ft_memset
- ft_bzero
- ft_memcpy
- ft_memmove
- ft_memchr
- ft_memcmp
- ft_strdup
Functions for numbers:
- ft_atoi
- ft_itoa
Functions to write to a file descriptor
- ft_putchar_fd
- ft_putstr_fd
- ft_putendl_fd
- ft_putnbr_fd
The bonus functions of libft deal with list manipulation. This part is worth an extra 25% to the final grade.
