CCalculator

Basic calculator written in C that is able to handle Big Integers in arbirtrary (2-16) base. It was written as a final project for the Programming 1 course (1st semester, 2021/22) at the MiNI WUT faculty.

Additionally, one extra line at the end of file is needed, giving three total empty lines at the end.

403

will yield given result
