Answer 1

Line 38, it should be like that:

if((action == '/')||(action == '*')||(action == '+')||(action == '-')||(action == '%'))

The condition “||(action == '%')” was missed.

Answer 2

Oops, how I forgot about it. Thank you very much! Soon I want to add degrees of numbers and square and cubic roots of numbers.
