C++ (Core) Coding Guidelines

C++  (Core) Coding Guidelines

Since 2011, when C++11 arrived, we all should be changing our coding style into modern C++ and at the same time keep good old tips. There are also general rules for programming and bug-free coding. Here’s a list of guidelines and other resources that might help you.

11 Debugging Tips That Will Save Your Time

11 Debugging Tips

Programming is not only typing the code and happily see how smoothly it runs. Often it doesn’t run in a way we imagine! Thus, it’s crucial to debug apps effectively. And, it appears that the debugging is an art on its own! Here’s my list of tips that hopefully could help in debugging native code.

Coding without Google

Some time ago an intriguing article appeared on reddit: “Do Experienced Programmers Use Google Frequently?”. The author discussed if expert programmers use google more often than novice coders. He mentioned than using google is actually a good thing. It helps to find best solutions, validate ideas, speed the development. Google nowadays seems to be a crucial part of any developer toolbox. That reminded me of old times.

Google benchmark library

Some time ago I wrote about micro benchmarking libraries for C++ - here’s the link. I’ve described three libraries: Nonius, Hayai, Celero. But actually, I wanted to cover fourth one. Google Benchmark library was at that time not available for my Windows environment, so I couldn’t test it. Fortunately, under the original post I got a comment saying that the library is now ready for Visual Studio!

Let’s see how can we use it.

Custom Deleters for C++ Smart Pointers

Custom deleters for C++ smart pointers

Let’s say we have the following code:

LegacyList* pMyList = new LegacyList();
delete pMyList;

In order to fully delete an object we need to do some additional action.

How to make it more C++11? How to use unique_ptr or shared_ptr here?

Visual Studio C++ Productivity Tips

Visual Studio Productivity Tips

Visual Studio is my main development environment. I’ve been using this tool probably since version 2003…2005. I am really happy that VS is getting more and more powerful these days and you can also use it on multiple-platforms (through VS Code, for web or cloud apps). What’s even better - it’s free for personal use or if you’re a small company (Community Version)! Today, I’ve prepared some productivity tips that might make your life a bit easier when developing an app in this Microsoft IDE.

I target native app development, but most of the rules should be generic to other languages as well.

The Matrix Updated

The Matrix demo project

Sometimes you can find interesting stuff in your past projects!
One day I was thinking about new post topics for the blog, but somehow, I got not much energy to do it. So, I just browsed through my very old projects (that are actually listed in my portfolio site). Memories came back and I decided maybe it’s time to refresh the ancient code files!

This time let’s go into Matrix!

Nice C++ Factory Implementation 2

Nice C++ Factory Implementation

The original code from my previous post about “nice factory” did not work properly and I though there is no chance to fix it.
It appears, I was totally wrong! I got a really valuable feedback (even with source code) and now I can present this improved version.

SFINAE Followup

SFINAE follow up

As it appears, my last post about SFINAE wasn’t that bad! I got a valuable comments and suggestions from many people. This post gathers that feedback.

Notes on C++ SFINAE

Starting with C++ SFINAE

This time I’d like to tackle a bit more complex problem: SFINAE. I’m not using this paradigm on a daily basis, but I’ve stumbled across it several times and I thought it might be worth trying to understand this topic.

  • What is SFINAE?
  • Where can you use it?
  • Do you need this on a daily basis?

Let’s try to answer those questions.

Revisiting An Old Benchmark - Vector of objects or pointers

Revisiting old benchmark code

Around one and a half year ago I did some benchmarks on updating objects allocated in a continuous memory block vs allocated individually as pointers on the heap: Vector of Objects vs Vector of Pointers. The benchmarks was solely done from scratch and they’ve used only Windows High Performance Timer for measurement. But, since recently I’m interested in more professional benchmarking libraries it would be good to revisit my old approach and measure the data again.

Micro benchmarking libraries for C++


After I finished my last post about a performance timer, I got a comment suggesting other libraries - much more powerful than my simple solution. Let’s see what can be found in the area of benchmarking libraries.
