C++ Quiz on on different aspects of a container which includes creation and design of new containers, vectors and sequences, types of inheritance and various class hierarchies, sequences like seq_con array class, seq_con vector class, stl – pair and heap, vtable, vptr, generators, array type manipulations, tuples, complex library, valarray, bitset and class relationships.

Class Hierarchies: A class hierarchy in C++ is a structure where classes are organized in a tree-like manner, with a base class at the top and derived classes below it. The derived classes inherit the properties and methods of the base class, and can also add their own unique properties and methods.

There are three main types of inheritance in C++:
Single inheritance: A derived class inherits from a single base class.
Multiple inheritance: A derived class inherits from multiple base classes.
Hierarchical inheritance: A derived class inherits from a single base class, and other derived classes can inherit from that derived class, forming a hierarchy.

Libraries: A C++ library is a collection of pre-written code that can be used by C++ programs. Libraries can provide a wide range of functionality, such as input/output, string manipulation, and mathematical operations.
The C++ standard library is a collection of libraries that are included with every C++ compiler. The standard library provides a wide range of functionality, such as containers, algorithms, and iterators.

Containers: A container in C++ is an object that stores a collection of other objects. Containers are implemented as class templates, which allows for flexibility in the types of elements supported.

The C++ standard library provides a variety of containers, including:
Sequence containers: These containers store elements in a specific order, such as arrays, vectors, and linked lists.
Associative containers: These containers store elements in a key-value pair, such as maps and sets.
Unordered associative containers: These containers store elements in a hash table, such as unordered_maps and unordered_sets.

Containers provide a variety of methods for accessing and manipulating the elements they store. For example, you can use the push_back() method to add an element to the end of a vector, and the find() method to search for an element in a map.
