Since its creation, C++ evolved continuously and it passed many major milestones from the C with classes to the rise of the new standards. From 1991 to 2011 the language evolved slowly and the evolution comes from the libraries like STL and Boost. However, from 2011 many features were added to the standard, thanks to the new standards C++11, C++14, C++17, and the coming C++20. Continue reading “C++ 17 In Detail Book Review”

Inside the Unreal Engine 4.5 source code
The Unreal Engine is a game engine developed by Epic Games, first showcased in the 1998 first-person shooter game Unreal. Although primarily developed for first-person shooters, it has been successfully used in a variety of other genres, including stealth, MMORPGs, and other RPGs.
Its code is written in C++ and it’s used by many game developers today. Its source code is available from GitHub and it’s free for students. Many amazing games were developed using this engine, it permits to produce very realistic rendering like this one. Continue reading “Inside the Unreal Engine 4.5 source code”
20 Years of Boost C++: Original Vision Review
In 1998 a proposal for a C++ Library Repository Web Site was posted by Beman G. Dawes. The original vision aims to satisfy two major goals:
- A world-wide website containing a repository of free C++ class libraries would be of great benefit to the C++ community. Although other sites supply specific libraries or provide links to libraries, there is currently no well-known website that acts as a general repository for C++ libraries. The vision is this: a site where programmers can find the libraries they need, post libraries they would like to share, and which can act as a focal point to encourage innovative C++ library development. An online peer review process is envisioned to ensure library quality with a minimum of bureaucracy.
- Secondary goals include encouraging effective programming techniques and providing a focal point for C++ programmers to participate in a wider community. Additionally, such a site might foster C++ standards activity by helping to establish existing practice.

Spotting C++11/C++14/C++17 Features in WinObjC: A Study
In a previous post we talked about the clang-modernize tool to detect where you can use some new C++11 features to modernize your C++ source code. But how can we easily detect where the new C++ features are used in a project?
Facebook and Google use C++11 extensively in their source code. Folly from Facebook as we discovered in a previous post use almost all of the C++11 features and I was curious to know if Microsoft also use the new C++11 standards in their open sourced code.

Lessons to learn from the CLang/LLVM codebase
It’s proven that Clang is a mature compiler For C and C++ as GCC and Microsoft compilers, but what makes it special is the fact that it’s not just a compiler. It’s also an infrastructure to build tools. Thanks to its library based architecture which makes the reuse and integration of functionality provided more flexible and easier to integrate into other projects. Continue reading “Lessons to learn from the CLang/LLVM codebase”
Optimize Memory in C++: Doxygen Case Study
When the processes running on your machine attempt to allocate more memory than your system has available, the kernel begins to swap memory pages to and from the disk. This is done in order to free up sufficient physical memory to meet the RAM allocation requirements of the requestor.
Excessive use of swapping is called thrashing and is undesirable because it lowers overall system performance, mainly because hard drives are far slower than RAM. Continue reading “Optimize Memory in C++: Doxygen Case Study”
Discover your C++ project internals: POCO case study
The POCO C++ Libraries are a collection of open source class libraries for developing network-centric, portable applications in C++.
POCO stands for POrtable COmponents. The libraries cover functionality such as threads, thread synchronization, file system access, streams, shared libraries and class loading, sockets and network protocols (HTTP, FTP, SMTP, etc.), and include an HTTP server, as well as an XML parser with SAX2 and DOM interfaces and SQL database access.
The modular and efficient design and implementation makes the POCO C++ Libraries well suited for embedded development. Continue reading “Discover your C++ project internals: POCO case study”
5 Common reasons of using namespaces in C++ projects
Namespaces were introduced to the C++ Standard in 1995 and usually they are defined like this:
A namespace defines a new scope. They provide a way to avoid name collisions.
Namespaces in C++ are most often used to avoid naming collisions. Although namespaces are used extensively in recent C++ code, most older code does not use this facility.
After exploring the source code of many C++ projects, here are some common reasons of using the namespaces in these projects. Continue reading “5 Common reasons of using namespaces in C++ projects”
Detect the obfuscated names in a C/C++ project
How many times do you already discover a code like this:
Maybe in some cases it’s not a big issue to have such code. But if this coding habit is used many times by the developers, it will cost a lot to the company. Each new comer who needs to debug or add a new feature will spent a lot of time to understand the existing codebase.
How to detect these obfuscated names to refactor them? Continue reading “Detect the obfuscated names in a C/C++ project”
