C++ / boost

How could we alter this program to create 10 threads?

#include  #include  #include  void workerFunc() { boost::posix_time::seconds workTime(3); std::cout << "Worker: running" << std::endl; // Pretend to do something useful... boost::this_thread::sleep(workTime); std::cout << "Worker: finished" << std::endl; } int main(int argc, char* argv[]) { std::cout << "main: startup" << std::endl; boost::thread workerThread(workerFunc); std::cout << "main: waiting for thread" << std::endl; workerThread.join(); std::cout << "main: done" << std::endl; return 0; }
