Programing paradigms

Programing paradigms

1. There are many types of programming paradigms, each with many different languages

2. Other paradigms include object oriented, functional and logical

3. Each paradigm is best suited to a particular type of problem. E.g using logic programming for natural language processing

4. imperative programming languages are those in which we tell the computer what to do; we tell it how to solve a problem. Procedural and object oriented programming are imperative paradigms

   • procedural programming uses sequence, selection and iteration to build procedures and subroutines. Examples include Basic, C and Pascal

5. declarative programming languages are ones where we tell the computer the qualities the solution should have. there are a number of subtypes of declarative language, including logic and functional programming

   • logic programming expresses a set of facts and rules. the facts and rules are then used to find a given goal. The most commonly used logic language is prolog
   • functional programming gives a description of the solution to a problem is built up through a collection of functions. Examples include Haskell and ML

6. A programming language is referred to as 'Turing Complete' if it can solve all the problems it has been proved computers can solve. most programing languages across different paradigms are 'Turing Complete'
