Libft is your first C library project. It involves implementing various standard C library functions, as well as additional functions, to create a utility library that can be used throughout your programming journey.
The Libft project consists of two main parts: the mandatory part and the bonus part. In the mandatory part, you'll re-implement several standard C library functions. In the bonus part, you'll work with linked lists and implement functions to manipulate them.
To use the Libft library, you'll first need to compile it into a static library file. You can do this by running the provided Makefile. Here are some useful commands:
makeormake all: Compiles the library.make clean: Removes object files.make fclean: Removes object files and the library.make re: Re-compiles the library.
ft_isalpha- Check if a character is an alphabetic character.ft_isdigit- Check if a character is a digit.ft_isalnum- Check if a character is an alphanumeric character.ft_isascii- Check if a character is a valid ASCII character.ft_isprint- Check if a character is printable.ft_strlen- Calculate the length of a string.ft_memset- Fill memory with a constant byte.ft_bzero- Set the first n bytes of memory to zero.ft_memcpy- Copy memory area.ft_memmove- Copy memory area with overlapping.ft_strlcpy- Copy string to specified size.ft_strlcat- Concatenate strings with size checking.ft_toupper- Convert a character to uppercase.ft_tolower- Convert a character to lowercase.ft_strchr- Locate a character in a string.ft_strrchr- Locate a character in a string, searching in reverse.ft_strncmp- Compare strings with a limited length.ft_memchr- Locate character in a memory block.ft_memcmp- Compare memory areas.ft_strnstr- Locate a substring in a string with a length limit.ft_atoi- Convert a string to an integer.ft_calloc- Allocate and zero-initialize memory.ft_strdup- Duplicate a string.
ft_substr- Create a substring from a string.ft_strjoin- Concatenate two strings.ft_strtrim- Trim specified characters from the beginning and end of a string.ft_split- Split a string into an array of substrings using a delimiter.ft_itoa- Convert an integer to a string.ft_strmapi- Apply a function to each character of a string and create a new string.ft_striteri- Apply a function to each character of a string with its index.ft_putchar_fd- Write a character to a file descriptor.ft_putstr_fd- Write a string to a file descriptor.ft_putendl_fd- Write a string followed by a newline to a file descriptor.ft_putnbr_fd- Write an integer to a file descriptor.
In addition to the mandatory functions, the bonus part involves working with linked lists. Here are the bonus functions:
ft_lstnew- Create a new list node.ft_lstadd_front- Add a node to the beginning of a list.ft_lstsize- Count the number of nodes in a list.ft_lstlast- Get the last node in a list.ft_lstadd_back- Add a node to the end of a list.ft_lstdelone- Delete a node and its content from a list.ft_lstclear- Delete all nodes from a list and free their content.ft_lstiter- Apply a function to the content of each node in a list.ft_lstmap- Create a new list resulting from the application of a function to the content of each node in another list.
