Whenever I answer n to "are you done yet", it skips the first question, and if I answer anything other than a character, it skips "do you wanna read your phonebook". Some help would be nice =). Started a less than a week ago.

It's because getline leaves a newline character in the buffer, which is subsequently read by cin. You should clear it before using cin>> with another getline() i think.
Tell me if it works.

I thought that's what I did. I used cin.clear(); after everything input.

Can I get some help, guys? That doesn't work.

That is not what you want. Try sync, get, ignore ...

Thanks, it worked, but can I ask what the difference is between sync and clear?
