All programming exercises are conducted in C.
Your code should always compile without warnings, when passing the flags -Wall -Wextra -std=c11.
Make sure your code is properly formatted using either your IDE/Text editor of choice, or by using a tool such as clang-format.
You can find an example .clang-format file in this repository.
Failure to consistently format code may result in lower scores.
Make sure to choose descriptive variable and function names. All names and comments must be written in English.
