here are some sample excutions of the program:
username? arnow
password? java
Welcome to the system
Sample Test Run #2
Given the same users.data file as above, execution of the program should look like:
username? weiss
password? dontremember
*** Invalid password - hint: woof-woof
username? weiss
password? puppy2
Welcome to the system
Sample Test Run #3
Given the same users.data file as above, execution of the program should look like:
username? sokol
password? CUNY
*** Invalid password - hint: college
username? sokol
password? SUNY
*** Invalid password - hint: college
username? sokol
password? BC
*** Invalid password - hint: college
