1. Introduction

Programming languages come in many forms or 'paradigms'. Each form of language offers advantages over other types and each one of course has some limitations as well.

Furthermore there are many languages available within each form. Sometimes the choice of a particular language is personal preference and familiarity or sometimes it is imposed by the company you are working for.

You need to know the main classes of programming and why you would use one type over another.

The main classes of programming languages are

• low level languages,
• object-orientated languages
• declarative languages
• procedural
• functional languages.
