I've approved your post, but let me forewarn you, nobody here will do your homework for you.
It looks pretty self-explanatory.


It says to compile it, but you don't really need to if you use the table to decipher what it is doing. Then answer the questions accordingly.

 

Basically, the program loads inputs and subtracts them until they hit 0 and then quits.
