C# vs C++ - C# / C Sharp

Greg

Is there a difference of opinion between C# users and C++ users as to whether
C# is generally a replacement for C++? I asked this in the C++ thread and
most people people who responded say that C# is not a replacement for C++.

Do C# promoters have a different view?

Its not an replacement but I would say for many projects its certainly an
alternative to traditional C++, and typically a lot faster to develop with
in the .NET IDE.

The resulting exeecutables are not as fast as native C or C++ (if you know
how to write C/++ of course) but its a very fast language to pick up and run
with, thus it has many advantages over coding in C++.

Thank you, yes it seems like C# is a great language to RAD prototype
something iteratively and then one can always convert it to C++.

If it is to convert to MC++ there is no reason (MC++ use MSIl as much as
C#).
If it is to convert to plain old C++, good luck... you should say: "one
could always spend Aeons convert it to C++"

Check out Kate Gregory's blog at http://www.gregcons.com/KateBlog/default.aspx.
She's a passionate promoter of of C++ and her thoughts are well worth reading.

It takes me less than half the time to develop a program in C# than it does
to develop the equivalent functionality in C++. I still can't write a low
level driver in C# tough...

Done any comparisons? Try it, you might be surprised.

I did some comparisons and was surprised and showed them to someone on
the C++ team and he told me that they were just what he expected.

The problem is that when most people think of .NET they think
'interpreter', or 'Java', or godforbid, Visual Basic. And so they think
'bad performance'. They shouldn't.

I think of the JIT compiler as being the back end of a C++ compiler (it
was written by people from the C++ team). If you discount the time that
the JIT compiler takes then for fully trusted code there is no reason
why it should be significantly slower than code generated by the
unmanaged C++ compiler. The only possible issue may be garbage
collection.

Of course, if you know of other areas of the .NET runtime which are
significantly slower than the equivalent in Win32 then you should post
them here so that we all can avoid using them <g>.

You still cannot (should not) in managed C++ either <g>.

But I am not sure if the OP is referring to C++ in general, or to
managed C++.

A good litmus test would be to write a prime number generator.

Then after 10000 or so just see how long it took in c# and c++.
