I need to convert this java program to a C ++ or C programming language?

import java.util.concurrent.*;

// professor thread completion standby professor.join();

// if studentScheduler thread not active, print exit message if (!studentScheduler.isAlive()) { System.out.println("Professor has locked up and left the building..."); } } catch (InterruptedException err) { err.printStackTrace(); } } } --------------------------------------------------------------------------------------------------------------- import java.util.concurrent.*;
