Object Oriented C: Single inheritance Part II

David M. Doolin, PhD — Mon, 07 Mar 2011 23:15:00 +0000

Here’s another installment on Object Oriented C programming. This time, we’re going to take a look at how inheritance allows you to simulate a generic function courtesy of the C preprocessor. If you have ever wondered how those spiffy objects in other programming languages always get “printed,” here’s one way to do it. First, let’s [...]

Single Inheritance In C Programming Language I: Nesting structures

David M. Doolin, PhD — Sat, 05 Mar 2011 16:11:12 +0000

The C programming language lends itself well to single inheritance object-oriented schemes, provided a little care is taken in the class structure. Consider the following definition: 1 2 3 typedef struct _object { int foo; } Object; 1 2 3 4 typedef struct _thing { Object o; double bar; } Thing; Right here, I know [...]

Simple Object Oriented Unit Testing For C Programming

Remember that giant blast of wind a few months ago? The wind that launched all my cool plants down the stairs? Well, here’s a picture of the re-potted collection. That’s about half of them, the other half are still languishing. Crassulae are tough as nails. I may re-pot the remaining… but these need to be [...]

How To Hide A Struct Member in the C Programming Language

David M. Doolin, PhD — Mon, 01 Jun 2009 16:54:55 +0000

Update: A friend pointed out a typo, which is now fixed in both the article and the code. Hiding a struct member in C is easy using incomplete types. There’s two ways to do it: Hide the whole struct definition Hide a single member of a struct Either way requires using a typedef to define [...]

gcc Linking Errors — Simpler than you think to fix

David M. Doolin, PhD — Fri, 24 Apr 2009 02:32:40 +0000

I’m sitting in the Cooper Square Hotel in Manhattan (long story), working on a nice little article on fast, small, simple unit testing, and looking south at downtown. I can see the cables and towers of the Williamsburg, Manhattan and Brooklyn Bridges. Cooper Square is where Bowery meets East Village. It’s nice. Think “Mission Hipster” [...]

LINK : fatal error LNK1181: cannot open input file ‘C:\Program.obj’

David M. Doolin, PhD — Fri, 20 Mar 2009 20:55:15 +0000

I’m working on a HUGE article titled something like “More VC++ Compiler & Linking Errors, with Real English Explanations” and it’s getting totally out of hand. Really long. And I need to go back through most of the article and make one more check (triple check) to make sure all the information is correct. Since [...]

C/C++ Naming conventions (Part II)

David M. Doolin, PhD — Wed, 04 Feb 2009 17:25:15 +0000

I estimate about half the code I have reverse engineered has inconsistent naming conventions. Actually, nearly all code I have ever reverse engineered (and most of the code I have written) has some naming inconsistency. At issue is grossly inconsistent naming. Consistent naming provides the following benefits: The sames kinds of objects, entities, types will [...]

[Note: If you do NOT find what you were looking for in this article, please leave a comment. I'll update as necessary to keep the information accurate, useful and current.] Once upon a time, I was a graduate student at UC Berkeley, and spent a fair bit of time in the engineering library. I recall [...]

C/C++ Naming conventions (Part I)

David M. Doolin, PhD — Tue, 19 Feb 2008 17:04:24 +0000

Update [2/19/2008] The Use Case article on Wikipedia provides more support for verb-object form. Update [2/19/2009] Added some links for literate programming. Naming conventions are an important and very practical aspect of literate programming. There are two fundamental requirements for naming conventions: Consistency of form, the “what it is” factor: Do the names [...]

Data Hiding in C: Programming Using Incomplete and Derived Types

David M. Doolin, PhD — Tue, 19 Dec 2006 22:38:43 +0000

>>>NOTE: You may want to start with a much simpler article in hiding member in structs. Data hiding and encapsulation in C is fairly easy using the notions of derived and incomplete types. A derived type is a user-defined type typically declared as members of a struct. An incomplete type is where the definition of [...]

Why C and not C++?

David M. Doolin, PhD — Sat, 09 Dec 2006 01:00:26 +0000

Why all this work coercing C into objected-oriented code, a form it wasn’t really designed for? This is a personal question spanning well over a decade of watching the C++ go from having no specification, to having a standard specfication not implemented anywhere, to having various parts of the standard implemented in various ways on [...]
