Implementation of some of the Standard C Library functions including some additional ones.
Libft is an individual project at 42 that requires us to re-create some standard C library functions including some additional ones that can be used later to build a library of useful functions for the rest of the program.
Disclaimer: Reinventing the wheel is bad, 42 makes us do this just so we can have a deeper understanding of data structures and basic algorithms. At 42 we're not allowed to use some standard libraries on our projects, so we have to keep growing this library with our own functions as we go farther in the program.
As you can see from the Subject, there are 5 sections:
- Libft Functions: Some of the standard C functions
- Additional functions: Functions 42 deems will be useful for later projects
- Bonus Functions: Functions 42 deems will be useful for linked list manipulation
- Personal Functions
- Project Functions:** Functions 42 Projects will be useful for later.

| ft_memset | ft_memalloc | ft_lstnew | ft_memicmp | get_next_line |

Notes:
- Most of the the files and function names are namespaced with an ft in front. It stands for 42 School.
My code is not the best, but it passed all the 42 tests successfully.
The goal is to create a library called libft.a from the source files so I can later use that library from other projects at 42.
To create that library, after downloading/cloning this project, cd into the project, copy all the files from the sub folders to the root directory and finally, call make:
git clone https://github.com/LYushan/libft
cd libft
make
Now to clean up (removing the .o files and the .c files from the root), call make clean
This is a list of my projects that use Libft extensively:
- get_next_line
- FDF
- ft_printf *Private repo

- 42FileChecker is a tiny bash script developed at 42 school for testing and checking the files according to the rules of the subjects.
