Question $4$

$0\mathrm{.}5$

Points

Which of the following statements relating to information hiding in object$-$oriented programming is FALSE?

Information hiding makes it easier for programmers to extend classes without worrying about who may be accessing class properties$/$variables$.$

Information hiding depends on the extensive use of global variables.

Information hiding makes it easier for programmers to re$-$use Classes without knowing the details of how they work internally.

Information hiding protects the values of variable from being changed inappropriately.
