Default, parameterized and copy constructor
Default, parameterized and copy constructor with example programs.
A constructor is a block of code which is
- similar to a member function.
- has the same name as class name.
- called automatically when an object of a class created.
A default constructor is the one which invokes by default when an object of the class is created.
It is generally used to initialize the default value of the data members.
It is also called no argument constructor.
Constructors that can take arguments are called parameterized constructors.
Sometimes it is necessary to initialize the various data elements of different objects with different values when they are created.
We can achieve this objective by passing arguments to the constructor function when the objects are created.
A copy constructor is used to declare and initialize an object from another object using an object as an argument.
Constructor which accepts a reference to its own class as a parameter is called copy constructor.
