Question
The following is for a computer science program using Dr.Java.
Prompt: Creating a simple game of hangman. Write a program to ask a user to enter a word, storing each character of the string into an array. Add enough line breaks to get the string off the screen. Set up a second character array the same length as the first and fill with '_' characters. Use this second array to present to another user, allowing them to guess letters. As they guess a letter that is in the original word, fill it in in the second array and re-display. If they guess a letter that is not in the word, take away a "try". Give them 6 tries to guess the whole word or they lose.
A big thing with this that I'm having difficulty with is replacing the '_' characters with correct guesses. For example, if the mystery word is "brick", it should initially show up like this _ _ _ _ _. If the user guesses 'c', the next output should be _ _ _ c _
