A quick question on (char letter : mAnswer.toCharArray())

hi could you explain in a very simple term what this method does?

(char letter : mAnswer.indexOf(letter))

I understand that mAnswer.toCharArray() breaks mAnswer into separate letters but what does "char letter:" do?

and this bit 

char display = '-'

Does it just store an empty char variable?

It's declaring a variable that will exist inside the loop. In each step of the loop, it will hold the individual char from the char array.
