What is a container class? What are the types of container classes in C++?

Question

Please provide some details on the static class variable, how it works and any example would be great.

Answer 1

A container class is a class that is used to hold objects in memory or external storage.

A container class acts as a generic holder.

A container class has a predefined behavior and a wellknown interface.

A container class is a supporting class whose purpose is to hide the topology used for maintaining the list of objects in memory.

When a container class contains a group of mixed objects, the container is called a heterogeneous container;

when the container is holding a group of objects that are all the same, the container is called a homogeneous container.
