Aggregate Classes
An aggregate class is a class with no user-declared constructors, no private or protected non-static data members, no base classes, and no virtual functions. Such a class can be initialized with a brace-enclosed comma-separated list of initializer-clauses. The following code has the same semantics in both C and C++.
struct C { int a; double b; }; struct D { int a; double b; C c; }; // initialize an object of type C with an initializer-list C c = {1, 2.0}; // D has a sub-aggregate of type C. In such cases initializer-clauses can be nested D d = {10, 20.0, {1, 2.0}};Read more about this topic: C++ Classes
Famous quotes containing the words aggregate and/or classes:
“We think of religion as the symbolic expression of our highest moral ideals; we think of magic as a crude aggregate of superstitions. Religious belief seems to become mere superstitious credulity if we admit any relationship with magic. On the other hand our anthropological and ethnographical material makes it extremely difficult to separate the two fields.”
—Ernst Cassirer (1874–1945)
“There are four classes of idols which beset men’s minds. To these for distinction’s sake I have assigned names—calling the first class Idols of the Tribe; the second, Idols of the Cave; the third, Idols of the Market-Place; the fourth, Idols of the Theatre.”
—Francis Bacon (1561–1626)
