SyntaxError: invalid syntax
Many implementations of printf acquire a lock to ensure that each printf call is not interrupted by other threads. In contrast, std::cout's overloaded << operator means that (even with a lock) one thread's printing of i and ' ' and '\n' can be interleaved with another thread's output, because std::cout << i << " " << endl; is translated to three operator<<() function calls by the C++ compiler.
