Daniel15’s Introduction to Object-Oriented Programming

April 11th, 2009

Well, back to posting coding-related blog posts, for now anyways :P . Seeing as a lot of people seem to be confused by Object Oriented Programming, I thought I’d post a quick (or maybe not so quick) post about what OOP is, the main features, and how it can benefit you. This is paraphrased from an assignment I had on OOP last semester at university. I use C# code examples throughout this, but the concepts are very similar in other languages. Note that in this post, I assume you know the basics of programming, and just want to learn more about object orientation.

Now, let’s begin looking at what OOP actually means. At its core, the Object Oriented paradigm consists of classes and objects. A class is a “thing” or entity that has a purpose, and an object is an instance of this entity. For example, a Car would be a class, and my car would be an object (instance of the Car class).

Using TCP sockets in Pascal, connect to remote servers

TCP sockets in Pascal are generally hard to use; Free Pascal doesn’t come with any high-level socket libraries by default, only a relatively low-level socket library. Some external libraries are available to make using sockets with Pascal easier, and one of these libraries is Synapse. Synapse is an easy-to-use socket library for Pascal, and in this blog post I’ll try to show how to use Synapse to connect to a remote server and send/receive data from it.
