Instance creation

Hello,
I get the same o/p for the 2 pieces of code below:
Base *b = new Base ;
b->test() ;
delete b ;

vs just saying:
(new Base)->test() ;

In the second case, how is the object created and what instance of the
object do we have to "delete" at the end of the program. It's a very
fundamental thing which I seem to be getting confused at. Inputs are
welcome.

Thanks

What is an "o/p"?

Just the same as in the first case. Dynamically with new.

Well, you didn't store the pointer to it, so unless Base's constructor or
the test() member function stores it somewhere, that pointer is lost and
you cannot delete the object.

o/p as in output.

hmm.. Thanks for the suggestion, I will ponder over it :)
