+# Two Word Random Password
+
+While generating a password by selecting random characters usually creates one that is relatively secure, it also generally gives a password that is difficult to memorize. 
+
+As an alternative, some systems construct a password by taking two English words and concatenating them. While this password may not be as secure, it is normally much easier to memorize.
+
+Write a program that reads a file containing a list of words, randomly selects two
+of them, and concatenates them to produce a new password. 
+
+When producing the password ensure that the total length is between 8 and 10 characters, and that each word used is at least three letters long. 
+
+Capitalize each word in the password so that the user can easily see where one word ends and the next one begins. 
+
+Finally, your program should display the password for the user.
