Achieving Clean Code can get harder when you go down to the nuts and bolts. Bit-manipulating code is very common when you go “low level” with your coding, usually with C. It may be needed when you manipulate HW registers with a certain bit structure, when you want to compress data elements to occupy bits […]

The Dreadful ‘Goto’
The ‘goto’ operation has a very bad reputation when it comes to high-level programming languages. I have heard many times the sentence “never ever use goto”. I think that the fear of ‘goto’ is generally justified since it can lead to horrible spaghetti code. If really abused, it can completely corrupt the structure of a […]
C Polymorphism – Part 2
In the first part of this post, a “classic” example of Polymorphism-like code in C was discussed. Let’s look at some production code I had a chance to refactor. After the refctoring, the code looks like another step forward towards the Polymorphic behavior of real OOP languages. For obvious reasons, I have modified the example […]
C Polymorphism – Part 1
Polymorphism is something usually associated with Object Oriented Programming, not with classic C. However, the notion of Polymorphic behavior definitely exists in C in a “lighter” form. You will not automatically get all the back-stage mechanisms OOP languages give you, but there are still time in which you can get a lot of code cleanness […]
