Converting decimal to hex and vice-versa
Are there any C++ functions or Windows functions that can be used to convert to hex and vice-versa?
For example if I have a variable whose value is 10 million how would I convert it to the hex equivalent, 989680?? And how would I convert back to decimal? I prefer standard C++ functions but will use windows or MFC functions if there is no other way.

or, in standard C++ (not c):
{
ostringstream oss;
oss << hex << 123;
cout << oss.str();
oss.str("");
oss << dec << 0x7b;
cout << oss.str();
}
{
ostringstream oss;
oss << hex << 123;
cout << oss.str();
oss.str("");
oss << dec << 0x7b;
cout << oss.str();
}
or, if you're just interested in printing:
cout << hex << 123 << dec << 123 << oct << 123;
etc.
cout << hex << 123 << dec << 123 << oct << 123;
etc.
I once wrote a helper function to do somclever onterpretation of numbers entered (various hex markers allowed, etc..) see

Hmm, ich mag besonders den 'Netz gegen Rechts'-Link auf der Hauptseite :o)
If this is the best of the site... well, perhaps I should change my profession ;-)
Nicht 'das beste' - aber es freut mich immer, das zu sehen :o)

Ya'll start speaking in a manner which everyone can understand, alright?
As an Israeli I find this misterious german dialog suspicious and scary!
(not really... :)
(well, a bit maybe...)

So, to translate it (and take away the scaryness, maybe):
Peter has a 'The Net against Nazis' button/link on his page, and I was just expressing my appreciation for that...
