For this assignment, you are to write a program that plays the game of Hangman. The assignment serves two purposes.
First, it is designed to give you practice with strings, pointers and file I/O. Second, it gives you a chance to write a program
that is larger than those you have written for most previous assignments. Large programs require more up-front organization
than small programs, and it is important that you begin to get experience with larger programs at this point in the course.
Because of the additional organizational work and the fact that there are more details to manage, you are strongly
encourage to work in teams of two for this assignment. For your version, you will use phrases rather than single words for
the user to guess
