It is possible by name mangling.
The compiler actually generates different names for the functions.
Read how Visual C++ compiler does this - Microsoft Visual C++ Name Mangling[^]

Mmmh, I'm confused now. I don't know if he was talking about function overloading or function overriding. He used the word overloading but he also talked about polymorphism (which has nothing to do with overloading but with overriding).

Overloading is also a type of polymorphism - compile time polymorphism.

There you have it.
Let's leave it to him to choose what he wants.

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.
|
|
|
|
|
sir so both function will take different memory.... is it correct then how???
plz
|
|
|
|
|
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).
|

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  ).

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.

As strange may appear (at least it appears strange to me), overloading is considered polymorphism (after all, you are issuing the same request on objects of different nature and the behaviour may be different on such different types).

Yeah, that's what Rajesh also said but I honnestly don't think that's what the OP meant by polymorphism
|

The OP request was fully polymorphic: it generated completely different reactions from the different subjects...  If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Yes, that's one of the reasons you never need a code obfuscator for ATL sources...If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

When I excute the developing program in VC6.0 debugging enviroment,the program run successfully.But when I excute the program of release version alone,appear the error infomation below:
microsoft Visual C++Runtime Library
Runtime Error!
Program: C:\Progra....
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
However,the program of previous release version excute successfully.why?
I need your help and suggestion,thanks.

Hi,
Please take a look at this article: www.flounder.com/debug_release.htm[^]

thanks for your suggestion,I hope some realistic operations to solve my question.

Firstly, both the debug builds and the release builds should be built with debug information. Some people erroneously believe that only release debug builds can be built with debugging information, but this simply isn't the case. Assuming you've got a release build with symbol files then proceed as you always would; break into the application with a debugger when the fault occurs and get a stack trace.Steve

Umm... Surely, you wanted to say 'debug builds' instead?

Could you give me some advices to solving the problem,thanks very much!
|
|
|
|
|
| I thought I did. I'll reiterate: Firstly ensure that the release build is built with debugging information. Then run the program under a debugger, break execution when the problem occurs and get a stack trace. Pick the thread that's displaying the runtime error message. Which part of this are you having problems with? Steve
