Given the following concurrent program.

Which part indicate the critical section?

Which part indicate the synchronization between the processes?

What are the names of the concurrent processes?

Is this a correct concurrent program? If yes, what will be printed. If not, can you make needed correction then write the output?

monitor boundedbuffer:

int $N=10$;

int buffer $[$N$]$:

int nextin, nextout:

int count:

cond notfull, notempty;

void append $($int $x)$

$\{$

buffer$[$nextin$]=x$;

nextin nextin $+1$
