If you get a good, new C++ book then you can find answers to the above questions (and to many others of the millions you posted before).
you can try to (m)alloc(ate) a bit amount of your money to buy a good C book too.
This can help you to delete some of the naive questions you're about to post and make us free to answer to other people.

I think he is simply looking for answers to his homework assignments.

Hence he has a lot of homework!

Because both are not the same

There are a lot of other good books...
Try to code a bit too.

The new-operator allows you to do other things before or just after the allocation of the memory and before the call the the constructor.
You can for example use the new-operator to create ("new") objects in a different memory scope.
I have used this to work with my own memory manager located on stack.

If you're asking what the difference is between "operator new" and "the new operator", there is none. Just two ways of referring to the same thing.

I'm stuck!
Ive created and application using C++, openGL and SDL and now want to release it for use on windows.
Thing is I cant seem to find a simple way to do this. Ive been on MSDN which give tutorials on ClickOnce and Windows installer deployment but dont really understand what I want to do.
Could anyone tell me the or give me some pointers on what steps I should take so that I am able to get my program in a format which I can distribute to whoever I want?
Any help would be appreciated

Does anyone know any way to get the selected item off of a CTreeCtrl on a different dialog? The only thing I have thought of is to save the index of the selected value to a database every time it changes.
Thanks

Can we discuss the design criteria for the usage of set_new_handler. Why is it used instead of using exceptions.
Also what is the implication os using the same at a class level.

Because you cannot handle memory leaks with exceptions. When an app runs out of memory it's mostly due to memory leaks(1). By definition you cannot recover memory leaks. So the best thing to do is to just terminate the app via the new handler.
(1) only Java Swing apps run out memory inherently.

you would only use this if you're developing a debugger or some kind of diagnostic application use to monitor a process access to memory. other than this you don't need to worry about it!

How do I subscribe to comp.lang.C++.moderated in outlookexpress or in RSS reader? Also are there any good C++/VC++ admirable newsgroup to which one can subscribe to?
|
|
|
|
|
Try first the non-moderated comp.lang.c++
No subscription necessary, just post the same way as to any other newsgroup. Before posting read the C++ FAQ[^].

Sorry, I don't use Outlook. Put the following line into your browser's address field and see what happens:

It can't, without a plugin of some sort. You can use OE, however.

I cant seem to find this anywhere, but does anyone know what WinAPI to call when doing a lookup of the windows Domain/Workspace ? Ive searched MSDN over and over and cant find a thing that has to do with what im trying to do. I thought GetDomainName() would work, but to no avail. It doesnt, thanx in advance!

main()<br />
{<br />
int x=2.4;<br />
if(x==2.4)<br />
cout<<"true";<br />
else<br />
cout<<"false";<br />

Well it is not working, help me out please!

You cannot compare FP numbers in this fashion. You'll need something like:
if (fabs(x - 2.4) < 0.00001)
cout << "true" << endl; See here for more.

in short, a computer cannot "always" represent a floating point number accurately in binary format, and a precision error will be inserted when converting back and forth between the floating point number and the binary representation.
for example :
2.4 can be "errored" to something like either 2.39999999 or 2.40000001
