C++ constructors

Constructors in C++ are special member functions that are automatically called when an object of a class is created. They have the same name as the class and can be used to initialize data members of the class.

There are two types of constructors in C++:

1. Default constructor: This constructor is called when an object is created without any arguments. It initializes the data members of the class to their default values.

2. Parameterized constructor: This constructor is called when an object is created with arguments. It initializes the data members of the class with the values passed as arguments.

In addition to these two types, there are also copy constructors and move constructors. A copy constructor is used to create a new object from an existing object of the same class. A move constructor is used to transfer the resources of an object to a new object.

Constructors can also be overloaded, which means that there can be multiple constructors with different parameters. This allows for flexibility in creating objects of a class with different initializations.

Constructors are an important concept in object-oriented programming, as they allow for the creation and initialization of objects in a structured and predictable manner.
