Need help printing the contents of a string that also exist in a vector

[bat9998]

Hi all,

For the last part of this problem, if player 2 loses the game of hangman, I need to display the letters they did get right. In order to do that, I believe that I need to traverse vector v for the elements that exist in the string hiddenword, and then print those characters that match.

Can anyone offer further guidance on how to do this? I have had a lot of fun on this problem, and I'd love to be able to sort out the final part.

Thanks!
