This means that the function can modify the elements of the array.

The change is visible in the main function because the array <code>arr<\/code> is passed by reference.<\/p>\n<p>Options B and C are incorrect because they do not include the address-of (&amp;) operator. Option D is incorrect because arrays are not automatically passed by reference.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Subscribe on
