Answer:
See explaination 
Explanation:
The code 
type printer = monitor
var P: array[0…2] of boolean;
X: condition;
procedure acquire (id: integer, printer-id: integer);
 begin
 if P[0] and P[1] and P[2] then X.wait(id)
 if not P[0] then printer-id := 0;
 else if not P[1] then printer-id := 1;
 else printer-id := 2;
 P[printer-id]:=true;
 end;
procedure release (printer-id: integer)
 begin
 P[printer-id]:=false;
 X.signal;
 end;
 begin
 P[0] := P[1] := P[2] := false;
end ;
Note: 
Monitors are implemented by using queues to keep track of the processes attempting to become active int he monitor. To be active, a monitor must obtain a lock to allow it to execute the monitor code. Processes that are blocked are put in a queue of processes waiting for an unblocking event to occur.

Current date formula:
=TODAY()
Current time formula:
=NOW()
 As you can see, the =TODAY() formula only includes the day, month and year. The =NOW() function displays more information, showing the day, month, year, hour and minutes (using a 24-hour clock)
