Multithreading :1.Create thread

We will be using std::thread class to create threads.
std:thread is introduced in C++11.
We can start creating threads by including the thread header file. To create a thread, we need to pass the code that needs to be executed in the constructor of the thread.
As soon as the thread object is created, a new thread is launched, which will execute the code passed to the constructor.


The constructor takes

• a function object
• a function pointer
• a  lambda expression
