Question

This is a very very basic question and I know one way is to do the following:

char buffer[33];
itoa(aq_width, buffer,10);

where aq_width is the int, but then I can’t guarantee what size of buffer I would need in order to do this… I can always allocate a very large buffer size, but that wouldn’t be very nice… any other pretty and simple way to do this?

Answer 1

std::stringstream ss;
ss << 3;
std::string s = ss.str();
assert(!strcmp("3", s.c_str()));
