C programming can be very tedious when one doesn’t have access to the highly useful standard functions. This project is about understanding the way these functions work, implementing and learning to use them.

For detailed information, refer to the subject of this project.

🚀 TLDR: this project consists of coding basic C functions (see below), which are then compiled
into a library for use in other projects of the cursus.

• ft_isascii - test for ASCII character.
• ft_isalnum - alphanumeric character test.
• ft_isalpha - alphabetic character test.
• ft_isdigit - decimal-digit character test.
• ft_isprint - printing character test (space character inclusive).
• ft_tolower - upper case to lower case letter conversion.
• ft_toupper - lower case to upper case letter conversion.

• ft_atoi - convert ASCII string to integer.
• ft_calloc - memory allocation.

• ft_bzero - write zeroes to a byte string.
• ft_memset - write a byte to a byte string.
• ft_memchr - locate byte in byte string.
• ft_memcmp - compare byte string.
• ft_memmove - copy byte string.
• ft_memcpy - copy memory area.

• ft_strlen - find length of string.
• ft_strchr - locate character in string (first occurrence).
• ft_strrchr - locate character in string (last occurence).
• ft_strnstr - locate a substring in a string (size-bounded).
• ft_striteri - apply the function all the elements of string.
• ft_strncmp - compare strings (size-bounded).
• ft_strdup - save a copy of a string (with malloc).
• ft_strlcpy - size-bounded string copying.
• ft_strlcat - size-bounded string concatenation.

• ft_putchar_fd - output a character to given file.
• ft_putstr_fd - output string to given file.
• ft_putendl_fd - output string to given file with newline.
• ft_putnbr_fd - output integer to given file.
• ft_itoa - convert integer to ASCII string.
• ft_substr - extract substring from string.
• ft_strtrim - trim beginning and end of string with the specified characters.
• ft_strjoin - concatenate two strings into a new string (with malloc).
• ft_split - split string, with specified character as delimiter, into an array of strings.
• ft_strmapi - create new string from modifying string with specified function.

• ft_lstnew - create new list.
• ft_lstsize - count elements of a list.
• ft_lstlast - find last element of list.
• ft_lstadd_back - add new element at end of list.
• ft_lstadd_front - add new element at beginning of list.
• ft_lstdelone - delete element from list.
• ft_lstclear - delete sequence of elements of list from a starting point.
• ft_lstiter - apply function to content of all list's elements.
• ft_lstmap - apply function to content of all list's elements into new list.

The library is written in C language and thus needs the gcc compiler and some standard C libraries to run.

1. Compiling the library

To compile the library, run:

$ cd path.. && make(excluding LinkedList func.) / make bonus (including LinkedList func.)

2. Using it in your code

To use the library functions in your code, simply include its header:

#include "libft.h"
