  Re: What is constructor?
Answer
# 1
A constructor is a special type of member function for
automatic initialization of an object.
when ever an object is created the constructor will be
executed automatically.
the name of constructor same as that of its class.the
constructor is declared with no return type,not even void.
constructor should be declared in the public section most
of the time.
