[C/C++] pthread parallel execution

Just started learning to use POSIX threads, but I find that every time I create a thread and/or join it, the calling thread halts until the called thread completes its iteration. How do I execute them parallel to one another?

Thanks.

Note that pthread_join is commented out... I had tried it before, but stopped. It's only using pthread_create at the moment... and still blocking.
