Basically, nothing. There would be a lookup in the method table for the
object, and then it would be executed.
Honestly, it's not even something to be concerned about.
The size of the ^type^ will increase with each member in the class, as
well as any derived classes. However, you ^REALLY^ shouldn't worry about
this. Unless you had hundreds of members though. However, at this point, I
wouldn't be worried about performance (it still wouldn't be an issue), but
because of design (one type with that many members is excessive, and poorly
designed).
Hope this helps.

I want to know incase there is any performance difference or overhead
in calling a base class method and a derived class method.
Basically I am talking about simple method that is not overridden nor
virtual. If I declare a method in the base class say M1() and another
in derived class M2(). Then I make a derived class object derived. I
then invoke these:
derved.M1()
derived.M2()
What difference would it be.
Also does the size of the class object increase with more method
members in the class. Incase I add methods to the base class would it
increase the size of the derived class also.
Thankx in advance to you all.
