If we overload operator $==$ for the class point as a member function $,$ which of the following implementations is correct?

Question $2$ options:

a$)$

bool point::operator $==($const point& p$)$

$\{$

return $($x $==$ p$.$get$\_$x$())$ && $($y $==$ p$.$get$\_$y$())$;

$\}$

b$)$

bool operator $==($const point& p$1,$ const point& p$2)$

$\{$

return $($p$1.$get$\_$x$()==$ p$2.$get$\_$x$())$ && $($p$1.$get$\_$y$()==$ p$2.$get$\_$y$())$;

$\}$

c$)$

None of these answers

d$)$

bool point::operator $==($const point& p$)$

$\{$

return $($x$,$ y$)==($p$.$x$,$ p$.$y$)$;

$\}$
