Have a Little Class
Let’s go ahead and toss in a class variable. We’ll use the variable @@users to keep track of all the users on our computer.
Instructions
1.
Add a class variable called @@users to your Computer class. Set it equal to an empty hash.
In your initialize method, set @@users[username] = password so that your @@users hash keeps usernames as keys with each username’s password as the associated value.
