Change this program so that it takes a command-line argument that it will

interpret as a username, and it will print out the information about that

user. It should print the username, name, email address, and home directory.

Example run.

./user_info.o cs50000

user: cs50000

name: Jeff Kinne

email: jkinne@indstate.edu

home directory: /u1/class/cs50000
