Hi,
There is no need to create an object of the base class, if you want to create an object of the derived class. It is automatically created internally. When you create an object of the derived class then, the constructor of the base class is called first and then the constructor of the derived class. Hence, depending upon the scope specified by access specifiers, we can directly the use the members of the Base class using the object of the Derived class.

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.

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
