Question $2$:

$(5$ Marks$)$

CO$2$ The following $($code in C$)$ provides an example of a race condition, if it were

executed by two processes roughly at the same time. Explain$-$ whatever bug could

arise for the race condition. Solve the bug using Mutex$/$Binary Semaphore stating

the differences between MUTEX and Binary Semaphore

int queue$[$SIZE$],$ i$=0$;$//$assume these are shared between processes

void insert$($int x$)$

$\{$

queue$[$i$]=$ x;

i$++$;

$\}$

Atomic wait and signal do not violate the mutual exclusion. Explain the reasons?
