Practical multithreading

In computer science, a thread of execution is a sequence of code instructions that can be managed independently by a scheduler of the operating system. On a Linux system, the thread is always part of a process. The C++ threads could be executed concurrently with each other via the multithreading capabilities provided by the standard. During execution, threads share common memory space, unlike processes, where each has its own. Specifically, the threads of a process share its executable code, the dynamically and globally allocated objects, which are not defined as thread_local.

Hello C++ jthread

Every C++ program contains at least one thread, and this is the thread that runs the int main() method. Multithreaded programs have additional threads started at some point in the execution of the main thread. Let’s have a look at a simple C++ program that uses multiple threads to print to the standard output:

#include <iostream>
#include <thread...
