A C++ equivalent

The following C++ code demonstrates how we can implement the threading program. It shows that there are some subtle differences between C and C++ with regard to outputting strings to the screen. However, as you will discover, C functionality can also be implemented in C++.

It also importantly introduces us to thread termination via the pthread_exit function.

As you will encounter C and C++ used heavily in many hardware projects designed for the Raspberry Pi, this program will give you a basic introduction to C++, which you can use as a jumping off point.

You can read more about C++ at http://www.cplusplus.com/doc/ and find a wealth of tutorials.

Our next task is going to be to create a new file under your c_programs directory:

vim first_cpp_prog.cpp

Let's start by adding the include statements to the top of the file:

#include <iostream>
#include <cstdlib>
#include <pthread.h>

Here we include a library to handle input and output, called iostream. This provides...
