This document discusses constructors and destructors in C++. It defines a constructor as a special member function that has the same name as the class and is called when an object is created. There are three types of constructors: default, parameterized, and copy. A default constructor takes no arguments, a parameterized constructor allows passing arguments to initialize values, and a copy constructor initializes an object using another object of the same class. A destructor is also a special member function that destroys the class object and releases the memory allocated by the constructor.

2. CONSTRUCTOR
What is constructor
 It is a special member function.
 It has the same name as the class.
 It is called when an object is created.
 Constructor does not have a return type.
 It cannot be private.
 It can be defined inside or outside the class.

3. Type of constructor
 Default Constructor
 Parameterized Constructor
 Copy Constructor

4. DEFAULT CONSTRUCTOR
Default constructor is the constructor
which does not take any argument
It has no parameter . It is called a zero argument
constructor.
NOTE:
If we do not define any constructor
explicitly, the compiler will automatically provide a
default constructor implicitly.

5. PARAMETERIZED CONSTRUCTOR
It is possible to pass argument to constructors.
To create a parameterized constructor simply add the
parameters to it the way you would to add other function.
Typically it is use to initialize the argument.
NOTE:
When the parameterized constructor is defined and
no default constructor is defined explicitly, The compiler
will not implicitly call the default constructor

6. Copy constructor
A copy constructor is a member function
that initializes an object using another object of the
same class.
copy constructor takes a reference to an
object of the same class as an argument.

7. DESTRUCTOR
What is destructor
 It is also the special member function as a
constructor.
 Destructor destroys the class object created by the
constructor.
 It is not possible to define more than one destructor.
 It is used release memory space occupied by the
constructor .
