The program can be compiled with the following command:
g++ main.cpp -lpthread
As you can see, we need to link the POSIX pthread library dynamically.
Check out the following screenshot and visualize the output of the multithreaded program:

I had blocked the main thread with pthread_join to force it to wait for the other three threads to complete their tasks first, failing which the main thread would have exited before them. When the main thread exits, the application exits ...
