declarative-programming

I'm trying to learn Prolog. This are my first steps with this language. As exercise I want to write program which can recognize some poker hands (Straight flush, Four of a kind, Full house etc.). I'm looking for good card representation in Prolog. I need to have possibility to check if one card is bigger than other, if cards are suited and so one. I have started with code: rank(2). rank(3). rank(4). rank(5). rank(6). rank(7). rank(8). rank(9). rank(t). rank(j). rank(q). rank(k). rank(a). value(2, 2). value(3, 3). value(4, 4). value(5, 5). value(6, 6). value(7, 7). value(8, 8). value(9, 9).

What is the difference between the declarative and procedural programming paradigms? Could you please provide some examples? What other programming paradigms exist? DigitalRoss Imperative There are several sub-paradigms of the imperative programming paradigm, such as the procedural or the object-oriented programming paradigms. In the imperative programming paradigm, you describe the algorithm step-by-step, at various degrees of abstraction. Examples of programming languages which support the procedural paradigm: C (and most other legacy languages) PHP, mostly In some sense, all major languages

If we've learned anything from HTML/CSS it's that, declarative languages (like XML) do a good job of describing User Interfaces because: It's easy to build code preprocessors that can template the code effectively. The code is in a well defined well structured (ideally) format so it's easy to parse. The technology to effectively parse or crawl an XML based source file already exists. The UIs scripted code becomes much simpler and easier to understand. It simple enough that designers are able to design the interface themselves. Programmers suck at creating UIs so it should be made easy enough

I have been searching the web looking for a definition for declarative and imperative programming that would shed some light for me. However, the language used at some of the resources that I have found is daunting - for instance at Wikipedia . Does anyone have a real-world example that they could show me that might bring some perspective to this subject (perhaps in C#)? A great C# example of declarative vs. imperative programming is LINQ. With imperative programming, you tell the compiler what you want to happen, step by step. For example, let's start with this collection, and choose the odd
