Declaration
Classes are declared as friends within the definition of the class to whom access is to be given; this prevents a class from giving itself access to another's protected members, which enforces encapsulation. The friend class has the same level of access irrespective of whether the friend declaration appears in either the public, protected or private sections of the class definition. Friend status is granted by using the friend keyword:

Famous quotes containing the word declaration:
“I enclose to you a copy of the declaration of independence as agreed to by the House, and also, as originally framed. You will judge whether it is the better or worse for the Critics.”
—Thomas Jefferson (1743–1826)
“[The Declaration of Independence] meant to set up a standard maxim for free society, which should be familiar to all, and revered by all; constantly looked to, constantly labored for, and even though never perfectly attained, constantly approximated, and thereby constantly spreading and deepening its influence, and augmenting the happiness and value of life to all people of all colors everywhere.”
—Abraham Lincoln (1809–1865)
“I foresee the time when the painter will paint that scene, no longer going to Rome for a subject; the poet will sing it; the historian record it; and, with the Landing of the Pilgrims and the Declaration of Independence, it will be the ornament of some future national gallery, when at least the present form of slavery shall be no more here. We shall then be at liberty to weep for Captain Brown. Then, and not till then, we will take our revenge.”
—Henry David Thoreau (1817–1862)
