Question about objects

[Default User]

Do you understand what C++ is? It's the C language, with a few
extensions bolted on like objects and polymorphism. So in any
malfunctioning code, the problem might be the C base code, or the C++
extension parts. So it's perfectly suitable to ask in comp.lang.c as
well as comp.lang.c++.

Lots of people here do. It is a language.

No, it is a different language. A number of things that are legal C are
illegal C++.

malfunctioning code, the problem might be the C base code, or the C++
extension parts.

No, because there is no "C base code" only C++ code when you are writing
C++.

So it's perfectly suitable to ask in comp.lang.c as
well as comp.lang.c++.

What makes you think the people in comp.lang.c++ don't know all of the
"C base code?"

No, it is not reasonable to ask in comp.lang.c about C++ code, and since
you know about comp.lang.c++ you have no good excuse for doing so.

Don't top post. Your reply belongs under or interspersed with the

Oh, and don't bother to reply. *PLONK*.

I posted to comp.lang.c in case people could see a problem with the
underlying C code - please dont remove this crosspost. Thanks.

OK.
Here's what's wrong with your program
from a C point of view:
There isn't any part of your program
that means anything in C.

Scrap it.

could someone please explain to me, why in the
following code the second approach does not work?

class Base {};
class Inherited : public Base{};
void foo(std::vector<Base> arg) {}

void main() {

Should be:
int main() {

std::vector<Inherited> v1;

// doesn't work
foo(v1);

There is no implicit conversion from vector<Inherited> to
vector<Base>.

I don't really follow this - could you give a fuller explanation?

It is not C. Please keep this out of c.l.c. F'ups set.

Please do not top-post. Your answer belongs after (or intermixed
with) the quoted material to which you reply, after snipping all
irrelevant material. I fixed this one. See the following links:

No it isn't. It has its own standard, which conflicts with the C
standard in various places. It has a generally different
attitude. Please cease cluttering c.l.c with this c.l.c++
material. The languages are different.

Why is it that you are asking people in this NG for something, but, when
they ask you for something (NOT to top-post), you throw mud in their face?

So why is this cross-posted to comp.lang.c++?

 

[Al Balmer]

Do you understand what C++ is?

Yes. However, apparently you don't. Whatever you imagine to be the "C
base code" is surely understood by the experts who contribute to
c.l.c++.

And please stop top-posting.
