How to write a multithreaded application using the native C++ thread feature

Interestingly, it is pretty simple to write a multithreaded application using the C++ thread support library:  

#include <thread>
using namespace std;
thread instance ( thread_procedure )

The thread class was introduced in C++11. This function can be used to create a thread. The equivalent of this function is pthread_create in the POSIX pthread library. 

Argument	Comment
thread_procedure	Thread function pointer

Now a bit about the argument that returns the thread ID in the following code:

this_thread::get_id ()

This function is equivalent to the pthread_self() function in the POSIX pthread library. Refer to the following code:

thread::join()

The join() function is used to block the caller thread or the main thread so it will wait until the thread that has joined completes its task. This is a non-static function, so it has to be invoked on a thread object.

Let's see how to use the preceding functions to write a simple...
