Answer 1

You declared `char string[20];`
It is a C-String, a char array, it is not a std::string. Your condition `if (string.size() >= 8)` doesn't work, because a char array doesn't have any method by the name 'size'.

Answer 2

You can use the sting type instead of a char array. The string type has a length() method that returns the strings length.
