Answer 3

Ahmed Jezi ,
as Oma Falk already mentioned: the code seems to be incomplete.

▪︎variable <text> is used but not declared and initialized
▪︎a function count_char() is called but it was never defined

further issues may also occur.

so please put the complete code in playground and link it here.
thanks!
