eExercise $1\mathrm{.}14.$ Consider the following main function:

int main$()\{$

int $a,**x$;

$x=$&$a$

$**x={\displaystyle \underset{?}{\overset{?}{}}}3(1,2,3)$;

$a={\displaystyle \underset{?}{\overset{?}{}}}3(**x,a,**x)$;

return $0$ ;

$\}$

Trace through the execution of the program, and draw the critical memory

configurations.

int main$()\{$

int $a,**x$;

$x=$ & $a$;

$**x={\displaystyle \underset{?}{\overset{?}{}}}3(1,2,3)$;

$a={\displaystyle \underset{?}{\overset{?}{}}}3(**x,a,**x)$;

return $0$ ;

$\}$
