Answer 3

In your first and second if - else you have two expressions but you try to make only one expression. the right way is to write if (65>age && age >=18) { ... }. And you should have a look at the if -else if - else statement. Its more readable because everyone can see that the diferent if statements be associated.
Your last age doesn't make sense because nobody would write a negative number for his age.^^
And i am not sure but shouldn't the cout be before cin to show a message for the use what he has to do?!
Hope I could help you. happy coding. :)
