How to convert int to string

Question

I this a good way to convert int to string?

    int a = 123456789;
    string str = static_cast<ostringstream*>(&(ostringstream()<<a))->str();

Possibly looking for http://stackoverflow.com/questions/228005/alternative-to-itoa-for-converting-integer-to-string-c?lq=1, but that cast could be to a reference and spare the ugly pointer syntax. — chris, Mar 29 '15 at 18:54

C++11 introduced std::to_string for this very purpose:

int a = 123456789;
std::string str = std::to_string(a);
