		// TODO
		// Here you must add code to do the following:
		// 1) Read a command from the console.
		// 2) If the command is 'e', print "Exit" and
		//    exit the program using System.exit().
		// 3) Otherwise, print the corresponding message
		//    for each command:
		//    'a' -> "Alligator"
		//    'b' -> "Bear"
		//    'c' -> "Cat"
		//    'd' -> "Dog"
		// 4) Loop until the console returns an 'e'.
