---------------------------------
*** BOOKING FOR THE FIRST CALL (1) AND THE SECOND CALL (2).
Both for the first and the second call, within four days before the date (1)
you should register using the online system http://delphi.uniroma2.it
--> You cannot register for both calls.
--> If you are an ‘online’ student, write ’online’ after your name, please.

*** HANDING-IN YOUR HOMEWORK.
Within four days before date (1) for the first call, and date (2) for the
second call, please send to:
   
al@iasi.cnr.it and pettorossi@info.uniroma2.it
a message with subject:
 
 al2012_Lastname_Firstname_EnrolmentNumber
and body:
  
Invio in allegato i miei elaborati per le due prove in itinere che ho fatto da
  solo/a. Firstname Lastname
You should attach to the message two text files (with extension .cpp or .java or
.txt). These files should contain your solution to the two homework
exercises. Each program should be documented and should contain instructions for
its compilation and execution. Please, include also some execution tests as
comments to the code of each program. The names of the files should be:
           al2012_Lastname_Firstname_EnrolmentNumber_CYKParser1
           al2012_Lastname_Firstname_EnrolmentNumber_LR1Parser2
If you are an ‘online’ student the names of the files should be:
           alonline2012_Lastname_Firstname_EnrolmentNumber_CYKParser1
           alonline2012_Lastname_Firstname_EnrolmentNumber_LR1Parser2

Do not add screenshots and strictly follows the above instruction, please.
Send the message with the two attached files, according to the above
instructions, even if you have done so for a previous exam call.
Normally, you cannot register to more than three exam calls per academic year.
