Hi,

Just wondering is a difference between the "+=" operator between C
and C#?


I ask as I have reverse engineered some C code to C# and am receiving
some differing results. I have traced it down to a line involving a
"+=" operator. The C clode uses floats but I am using double, but this
should not make a difference right?

Just wondering if anyone has any comments or suggestions or user
experiences that thay would like to share.

Thanks,
Al.

You happen to have a case where I would have thought there would not be
much difference, but you really need to ask in a C# group. When you
do (or if you post similar questions here) it really helps to have
actual code (especially including the types of the various objects)
and what you see as going wrong.

I don't think so. Even with the simplest arithmetic types for x and
y, x += y does not mean the same in the two languages (but I am not an
expert in C#). Of course, if x and y are not plain types the effect
is wildly different.

No idea. Why would you ask a C# question in a C newsgroup?

If you have specific questions about C's "+=" operator, this is the
place to ask. If you want to know how C's "+=" operator works in
general, a good C reference or the C standard would be better. If you
want to know something about C#, you're in the wrong place.

For the same reason that he would ask a C question in a C# group.

It isn't a "C#" question, it's a "C and C#" question. This isn't the
ideal place for it, but nor is a C# group.

Some have suggested that he's more likely to find people who know both C
and C# in a C# group than a C group; I don't know if that's true, but
from evidence to date there don't seem to be many here who know both.

We have no idea. This is c.l.c, and we discuss the C langage. C#
is something else.

These days, I don't think CBF is authorized to speak for CBF.
