C++

Theoretical basis:A stack is a linear table of operations that is scoped to the end of the table. The end of the table is inserted, deleted, and so on, so it has a special meaning, the footer is called the top of the stack, the other end is fixed,

Use of C + + MultisetThe data mapping relationship in the multiset will not be a one-to-one relationship, but one-to-many, which means that an instance with the same key can be inserted in the container. On the organizational way, LZ made the

When some or all of the direct base classes of a class are derived from another base class, in this direct base class, the members that inherit from the base class above have the same name, and those of the same name of the object of the derived

There is a flaw in the simple factory model that violates the open and closed principle. The factory method mode avoids just one point.Opening and closing principle definition: A software entity should open for extension and close for modification.

Separating the creation and use of objects, so that users do not have to care about object creation details when working with objects, thus reducing the coupling of the system, making the design easier to modify and extend the use of, the client
