The C++ standard library offers a list of practical, statically variety-Risk-free, and effective containers. Illustrations are vector, record, and map: vector vi(ten); vector vs; listing lst; record l2 map tbl; map< Vital,vector > t2; These containers are explained in all superior C++ textbooks, and may be favored about arrays and "house cooked" containers Unless of course There's a superior motive never to. These containers are homogeneous; that is certainly, they keep components of the exact same type. If you'd like a container to hold features of various different types, you should express that both to be a union or (usually significantly better) to be a container of pointers to a polymorphic variety. The classical illustration is: vector vi; // vector of pointers to Designs In this article, vi can maintain features of any style derived from Shape. That is certainly, vi is homogeneous in that all its things are Styles (for being exact, tips that could Shapes) and heterogeneous within the sense that vi can maintain elements of a wide variety of Styles, for instance Circles, Triangles, and so on. So, in a sense all containers (in just about every language) are homogenous mainly because to make use of them there have to be a common interface to all factors for customers to depend on.
can be an extension of C's struct) which includes a 'tag' which can discover not only its individual style but its location in the sort hierarchy.
