Question

A couple questions about semantics and performance:

x = 0;
While (x < 10) {
  std::cout << "Some text here to send to cout";
  ++x;
}

Im using gcc 4.7, Should the text to stream be wrapped inside of a std::move?

Like this:

   x = 0;
    While (x < 10) {
      std::cout << std::move("Some text here to send to cout");
      ++x;
    }

And while I am asking, is it better in cases like this to just make the string static like:

x = 0;
While (x < 10) {
  static const char* s = "Some text here to send to cout";
  std::cout << s;
  ++x;
}

Moving a string literal won’t really do you much good: It will yield a pointer in any case and this pointer will be passed by value. With respect to making the string literal static, I would expect that it make no difference at all.
