However Should the caller includes a const MyFredList a or const MyFredList& a, then a will simply call the const subscript
The C++ common library supplies a list of helpful, statically kind-safe, and successful containers. Examples are vector, list, and map: vector vi(10); vector vs; checklist lst; record l2 map tbl; map< Critical,vector > t2; These containers are described in all good C++ textbooks, and will be favored about arrays and "household cooked" containers unless there is a excellent motive to not. These containers are homogeneous; that's, they hold features of precisely the same type. If you prefer a container to hold factors of numerous differing kinds, you will need to express that both like a union or (ordinarily far better) like a container of tips to a polymorphic type. The classical example is: vector vi; // vector of tips that could Designs Listed here, vi can maintain components of any style derived from Shape. That is, vi is homogeneous in that all its things are Shapes (for being specific, pointers to Styles) and heterogeneous inside the sense that vi can hold aspects of a wide variety of Designs, including Circles, Triangles, and so forth. So, in a way all containers (in every single language) are homogenous simply because to make use of them there must be a common interface to all features for customers to rely upon.
