Answer / pranab dutta

A constructor is a member function of a class that is used
to create objects of that class where as a method is an
ordinary member function of a class.
Constructor has the same name as the class itself and
Member has its own name.
A Constructor has no return type, and is invoked using the
new operator.. Whereas a Member has a return type (which
may be void), and is invoked using the dot operator.
