This is an extract from the code fragment:

$6$: class A

$7$: $\{$

$8$: private:

$9$: int x;

$10$: protected:

$11$: int getX$()$;

$12$: public:

$13$: void setX$()$;

$14$: $\}$;

$15$:

$16$: int A::getX$()$

$17$: $\{$

$18$: return x;

$19$: $\}$

$20$:

$21$: void A::setX$()$

$22$: $\{$

$23$: x$=10$;

$24$: $\}$

The reason why line $18$ is a valid access in this code fragment, is because the variable x is a private data member of the class A$.$ Private data members can only be accessed by other member functions and operators of the class A$.$ getX$()$ is a member function of class A and therefore line $18$ is a valid access.
