The producer-consumer problem is a classical multi-threaded synchronization problem in concurrent programming. Today, we will try to address it in C++ with mutexes. This tutorial consists of three parts. First, we define and analyze the challenging part of the quiz. In the second section, we explain and learn to use…

When building a complicated C++ application, the process can involve multiple tasks including pre-processing, compilation, linking, library generation, etc. Most of the time, for time-saving purposes, we only want to re-run certain steps but not all to rebuild the application reflecting an incremental change. It’s hard to bookkeep what’s changed…

In the previous article of this serials, we introduced the basics concepts in a version control system (VCS) — repository, commit and branch. We know code change is recorded as a commit. The next thing is to make a commit. That sounds like an easy job — modify the file…

Version control systems (VCS), also known as SCM (Source Code Management), are tools to help software development teams to manage changes to source code over time. It is the one tool every software developer must deal with in their daily work. This series is written to help beginners getting started…

Move semantics and rvalue references are two advanced and confusing features added in C++11. In this article, I will explain what they are and why they are needed. Let’s start with the main problem they are trying to tackle (yes, together). Problem: Unnecessary Copy of Objects C++’s major advantage compared to other programming languages is…

In this tutorial, we will talk about libraries in C++ and how to create/use them. A library is a collection of pre-compiled code that can be re-used by programs. There are 2 types of libraries: static library and dynamic library. 1. Static Library vs Dynamic Library A static library (or archive) contains code that is linked…

In the last tutorial, we talked about the basic compilations steps (preprocessing, compilation, linking) in the C++ and two important concepts “forward declaration” and “one definition rule”. If you haven’t read it, I strongly recommend reading it first. In this tutorial, we dive deep into one place where people made…

In the last tutorial, we compiled a simple single source file C++ program. However, most programs consist of multiple source files. It’s also good practice to separate source code into multiple files for better organization. …

This is a series of tutorials to help you start on C++ development (in Linux/macOS) and get familiar with useful tools. It aims to help people who have basic knowledge of C++ language and want to know more about the C++ compilation/debugging/development process in general. The tutorial will mostly focus…
