Answer / sujatha
CLASS TYPE TO CLASS TYPE:
In class to class type this can be achieved through either
by using TYPE CONVERSIONS OR BY USING CONSTRUCTORS.
here one class object is convrted into another class object
COPY CONSTRuctor:
here we r copying already existing object value to new
object of the same type.
and copy constructor will get called when we are creating
new object of the class at the same time we r intializing
the object with the already existing object.
ex:
A a1; //a1 is object of class A
A a2=a1 //a2 object of class A. a2 is a new object and a1
//is already existing object.
