¿What's Libft?

Libft marks the beginning of the path at 42 School. It consists of recreating key functions to understand them thoroughly, and inspires us to develop our own customized functions according to our needs.

Libft's content

1. Libc functions: Essential functions built into C for basic programming operations.
2. Additional functions: Complementary functions that expand the knowledge of memory allocation.
3. Bonus functions: Extra functions that teach about linked lists manipulation.

Libft: From Easy to Difficult (According to me)

As we move forward with the project, the functions become increasingly challenging. In light of this, i have proposed a sequential list for implementation.

Libc functions:

Name	Description
ft_isalpha	Checks if it is an alphabetic character.
ft_isdigit	Checks if it is a digit.
ft_isalnum	Checks if it is alphanumeric.
ft_isascii	Checks if it is an ASCII character.
ft_isprint	Checks if it is a printable character.
ft_toupper	Converts a character to uppercase.
ft_tolower	Converts a character to lowercase.
ft_strlen	Calculates the length of a string.
ft_memset	Fills a block of memory with a specific byte.
ft_bzero	Sets the first n bytes of memory to zero.
ft_strlcpy	Safely copies a string.
ft_strchr	Finds the first occurrence of a character.
ft_strrchr	Finds the last occurrence of a character.
ft_strncmp	Compares two strings up to n characters.
ft_strnstr	Finds the first occurrence of a substring.
ft_memcpy	Copies n bytes of memory from one location to another.
ft_memchr	Finds the first occurrence of a byte.
ft_memcmp	Compares the first n bytes of memory.
ft_atoi	Converts a string to an integer.
ft_strlcat	Safely concatenates strings.
ft_memmove	Safely copies n bytes of memory.
ft_calloc	Allocates memory and initializes it to zero.
ft_strdup	Duplicates a string into a newly allocated space.

Additional functions:

Name	Description
ft_substr	Creates a substring from a string.
ft_strjoin	Joins two strings into a new string.
ft_strtrim	Trims the beginning and end of a string.
ft_itoa	Converts an integer to a string.
ft_split	Splits a string into an array of strings.
ft_strmapi	Applies a function to each character of a string.

Bonus functions:

Name	Description
ft_lstnew	Allocates a new list element.
ft_lstadd_front	Adds an element to the beginning of a list.
ft_lstadd_back	Adds an element to the end of a list.
ft_lstsize	Counts the number of elements in a list.
ft_lstlast	Returns the last element of a list.
ft_lstdelone	Deletes a list element.
ft_lstclear	Deletes all elements of a list.
ft_lstiter	Iterates over a list and applies a function to each element.
ft_lstmap	Iterates over a list and applies a function to each element to create a new list.
