Every kata involving strings is at least 6kyu in C.

A user made the nice effort to group all 8kyu C katas together according to a C introductory book. Maybe it can help you find good actual beginner level kata: https://github.com/darrellroot/Computer-Science-Education-Resources/blob/main/Codewars-Problems-By-Stephen-Prata-Chapter.md

why 21st if 2000 is 20th century??

Fixed.

So, i edited the tests and switched the floats to doubles, and my code could work, thanks!

Should be fixed, please verify. You need to reset the trainer to see changes, so remember to back up your code!

So apparently I did not update sample tests :/ I will fix this tomorrow, sorry for that. Until then, you can edit sample tests and change all floats to doubles.

Where do you see the float? it should not be there anymore, I changed all floats to doubles recently.

Maybe I forgot to change one place, or maybe you have an old version of code in your trainer?

Why in tests the definition of the function is different from the code itself? (double (double) vs float (double))

Approved
