Hello! Tell me why the code does not work. Does not display the result. No mistakes.

Answer 1

The result of a, b and c are 5, 5 and 8 respectively.
These variables are (unsigned) chars and the values 5 and 8 are unprintable characters, so they appear invisible.

Might want to change their type to an (unsigned)int instead of a (unsigned)char.

Btw, global variables pretty much do count as a mistake, even if it does compile. :)

Answer 2

Many thanks. I think I get it. I also found a mistake and my result is now not 5.5.8 but 5.4.8 :)
