   1. Use C/C++ to Write a TCP client-server program that shows the date, 
      who is who is logged on, and the message of the day of the server 
      machine. The program also allows the client talk to the server.
      Once the client connect to the server, the server should display 
      the following menu on the client:

               =================== Menu ====================
                date - Print the system date and time 
                who  - Show who is logged on
                motd - Show the message of the day
                talk - Talk to the server
                quit - Quit the system
               =============================================
                Enter command >

      The client should send a command to the server. Upon receipt of the 
      request, the server should start a new process or thread to process 
      the request. The new process or thread can re-direct standard output 
      to the socket and execute the correct code. The code for each request 
      can be done by running "/bin/date", "/usr/bin/who", and "cat /etc/motd".
      Refer to the template programs.
      
      If the server receives the talk command, the client and server can
      start to exchange the message. A possible talk session could look 
      like:

      server> Welcome to the talk session.
      client> I'm testing my messager. 
      server> I saw your message. 
      client> My program works.
      server> We finally finish the assignment.
      client> Bye

      After typing "Bye" or "Ctrl-D" or any other command specified in your
      design, the client closes the talking session.

      Note: Use last five digital of SSN as your port number.

      (50 points)

      Note: The talk function is optional for undergraduate students and
            count 10 bonus points for undergraduate students.

   2. Write the same program using Java. (50 points)

   3. Allow C/C++ client to call Java server and Java client to call C/C++ 
      server. (5 bonus points)
