Run Time Type Information ( RTTI ) : Run-time type
information (RTTI) is a mechanism that allows the type of
an object to be determined during program execution.
There are three main C++ language elements to run-
time type information:
The dynamic_cast operator : Used for conversion of
polymorphic types.
The typeid operator : Used for identifying
the exact type of an object.
The type_info class : Used to hold the type information
returned by the typeid operator.

for example A,B,C,D are class all the 4 class contain one method who() but the method who() implementaion is differnet among each class. the relation among the 4 class are A is base class and is inherited by B and C.and from this two B and C where D is inherited. the question is i want to display the output who() method in all the classes(A,B,C,D)the output of who() method is diferrent amond all the class(A,B,C,D) ------A------ virtuval who(print a) override | | who(print b) B C override who(print c) | | -------D------ override who(print d)
difference between abstraction and encapsulation with progarammatic eg. hi,just recently i went for an interview .The interviewer asked what is the difference between abstraction and encapsulation with programmatic eg. I gave the answer as encapsulation mean hiding the relevant data which is not useful for the user, eg a electric fan .hiding the information how the electricity is converted into machanical energy. abtraction showing only the relevant data to the user eg electric fan. it look ,its color ,it design etc only relevant data. Then the interviewer asked me, give me some programmic eg .I Said Let assume a web form having control like textbox,button etc. The user can view textbox,button etc this is the eg of abstraction and when the user click on the button how he is redirected is not known by the user is the eg of the encapsulation. Am I Correct .was the answer given by me is perfect .now i am planing to go for an another interview should i give the same answer.IF not please suggest me a better answer.with some good eg Please help
