A picture is worth a thousand words: Visualize your C/C++ Projects

A picture is worth a thousand words” is an English idiom. It refers to the notion that a complex idea can be conveyed with just a single still image or that an image of a subject conveys its meaning or essence more effectively than a description does.

This idiom could also be applied in software programming. Indeed you can easilly understand a mini project when exploring its source code. However a big project become complex and not easy to understand.  In such cases it’s better to visualize the source code using graphs and diagrams to assist the developers understanding the source code.

Want to modernize your C++ codebase, check first the banned C++11/C++14 features from the Google style guide.

The refactoring is defined as the process of changing a software system in such a way that it does not alter the external behavior of the code yet improves its internal structure.

We can enumerate three decisions made by the managers concerning the code refactoring: Continue reading “Want to modernize your C++ codebase, check first the banned C++11/C++14 features from the Google style guide.”

Flashback to explore the C++ algorithms implementations over years.

Before the initial standardization in 1998, C++ was developed by Bjarne Stroustrup at Bell Labs since 1979, as an extension of the C language as he wanted an efficient and flexible language similar to C

In 1983, “C with Classes” was renamed to “C++” , adding new features that included virtual functions, function name and operator overloading, references, constants, type-safe free-store memory allocation (new/delete), improved type checking.

Tracking the hidden duplicate code in a C++ code base.

It’s known that the presence of duplicate code has negative impacts on software development and maintenance. Indeed a major drawback is when  an instance of duplicate code is changed for fixing bugs or adding new features, its correspondents have to be changed simultaneously.

The most popular reason of duplicate code is the Copy/Paste operations, and in this case the source code is exactly similar  in two or more places , this practice is discouraged in many articles, books, and web sites.However,  sometimes it’s not easy to practice the recommendations, and the developer chose the easy solution: the  Copy/Paste method.

The C++20 Concepts is the missing feature to eliminate the generics paradigm drawbacks.

As Bjarne Stroustrup points out, “C++ is a multi-paradigmed language.” It supports many different styles of programs, or paradigms, and object-oriented programming is only one of these. Some of the others are structured programming, and generic programming. In the last few years C++ experts like Andrei Alexandrescu, Scott Meyers and Herb Sutter promotes the uses of the generic programming and they qualify it as Modern C++ Design.

Here’s what say Andrei Alexandrescu about the Modern C++ design:

Modern C++ Design defines and systematically uses generic components - highly flexible design artifacts that are mixable and matchable to obtain rich behaviors with a small, orthogonal body of code.

Three assertions are interesting in his point of view: Continue reading “The C++20 Concepts is the missing feature to eliminate the generics paradigm drawbacks.”
