C is a low-level programming language and we often end up reinventing the wheel as the C standard library (`libc`) is quite small and in my humble opinion, not well designed.
|
||||
|
||||
**libcproject** solve this by providing common functions or data structures (`dictionary`, `linked_list`, `queue`, `stack`, etc.) we might need in our C projects.
