    Static/compile time polymorphism has another form also, which is extensively used by ATL classes. http://en.wikipedia.org/wiki/Curiously_recurring_template_pattern[^]

    Yes, that's one of the reasons you never need a code obfuscator for ATL sources...

        sir i want to know that if i write two function with same name(Polymorphism function overloading) then both function will take same memory or different.. if both will take same memory then how???

          They will actually become 2 different functions with different names. The change in names is done by the compiler and this is called name mangling.

              Did you follow our discution ? If yes, do you understand the difference between function overloading (two functions with the same name but different arguments) and function overriding (a function which is redefined in a child class) ? So please, indicates which is the exact case you are interested in, because these are two completely different cases.

                In case of overloading yes. It still isn't clear (at least for me) if he really meant overloading (he didn't answer the question, just put the words in a different order ;P ).

                  Anyway, if you meant overloading or overriding, both functions will start at different memory addresses (two different functions cannot start at the same memory address, it doesn't make sense).

                      When you overload a function, basically you're giving the same name to two different functions (the compiler produces two functions with two different names in the object file) hence two different portions of code memory are, of course, used. :)
