In this video we will learn about what is the Use Of join(), detach() and joinable() In Thread In C++ (C++11)

JOIN NOTES
0. Once a thread is started we wait for this thread to finish by calling join() function on thread object.
1. Double join will result into program termination.
2. If needed we should check thread is joinable before joining. ( using joinable() function)

DETACH NOTES
0. This is used to detach newly created thread from the parent thread.
1. Always check before detaching a thread that it is joinable otherwise we may end up double detaching and
double detach() will result into program termination.
2. If we have detached thread and main function is returning then the detached thread execution is suspended.

NOTES:
Either join() or detach() should be called on thread object, otherwise during thread object�s destructor it will
terminate the program. Because inside destructor it checks if thread is still joinable? if yes then it terminates the program.
