            char Y = 'y';
            char N = 'n';

            if()
            {}
        }
    }
}

Thanks for your answers!

You can't have an empty if(). The compiler tells you it expects an expression before the closing paren.

The error is pointing to the empty parens in the "if () {}" --there must be a boolean expression inside the parentheses.
