How could I convert a Long Long Int into string?

i can convert a int by itoa()
i can convert a long by ltoa()
but how about long long?

So far as i know, itoa and ltoa are not ANSI compliant.

I use sprintf(str,"%d",num) for int, and sprintf(str,"%lld",num) for long long int. Here str is the string, and num is the integer variable.

Alternatively, you can use an ostringstream for all kinds of output formatting, including long long.

[cpp]
#include <sstream>

string longlongtostring(long long x) {
ostringstream os;
os << x;
return os.str();
}
[/cpp]

Cool.

Didn't know how to do it in C++. Thanks.
