hi,
in c there is a way of getting a unsigned long long into a char array by using sprintf, is there a method in c++ that gets an ull into a string?
thx

stringstream - but I thought you weren't supposed to use C++?

Compilers can produce warnings - make the compiler programmers happy: Use them!
Please don't PM me for help - and no, I don't do help over instant messengers.
how do u use it?
unsigned long long input;
stringstream ss;
string s;
s << input;
EDIT:Code:unsigned long long input = 1234ULL; stringstream ss; string s; ss << input; ss >> s; // or s = ss.str();
Oops, unsigned long long, not unsigned long. Note that (signed/unsigned) long long is non-standard in C++ though available as an extension on some compilers.

and __int64 on some others.

Yes there is, but the conversion format still depends on your OS/Compiler (until everyone supports C99 properly).
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
I assume unsigned long long would be unsigned __int64.
I typically just use the macros from the headers, UINT64 or INT64.
