hangman.cpp

/*
	Name: Hangman game!
	Student Name: Nicholas Smith
	Description: Program that reads categories and words from a file and ask the user to enter a category to guess a word from the selected category.
				 Displays the hangman design to the console everytime a letter is guessed incorrectly.
	Still need to provide comments in this program! :(
