====== First assignment for C-monday ======

Make a calculator in C programming language
You can take 2 approaches
  * first - closer to the desktop apps, where after running the program, you write <number> <space> <operator> <space> <number>
  * second - you utilise argc and argv to write the number and operand while executing ''./calculator''

First tier 
  * enum + switch, parsing the operator while removing whitespace around it
  * float parsing (atoi)
Second tier
  * Proper float operations, check in most languages, what happens with ''0.1 + 0.2''. Utilise libc strtof and strtod
