Programming paradigms What is programming? Programming is writing‚ designing and maintaining the source code of a computer programme. There are 3 different types of programming: Procedural Object orientated Event driven Procedural Procedural programming is a term used to describe the way which a computer programmer writes a program. This method of developing software which is also called an application revolves around keeping code as concise as possible. Its operators by reading the tasks that are

Evolution of Programming Languages Generations Most books and articles on history of programming languages tend to discuss languages in term of generations.This is useful arrangement for classifying languages by age.I agree that whatever a few of we ‘more mature’ software engineers get together‚ we cannot ever seem to agree on wht constitutes the generation of computer languages.We know that Formula Translation (FORTRAN) was probably a first-generation languges.Does that make FORTRAN 77 and WatFor

Ruby is a dynamic‚ open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write. Ruby is a language of careful balance. Ruby is a pure object-oriented programming language. Ruby is simple in appearance‚ but is very complex inside‚ just like our human body. In Ruby‚ everything is an object. Every bit of information and code can be given their own properties and actions. Ruby has features that are similar to those

COMPUTER PROGRAMMING Programming languages for computers are developed with the primary objective of facilitating a large number of persons to use computers without the need to know in detail the internal structure of a computer. Languages are matched to the type of applications which are to be programmed using the language. The ideal language would be one which expresses precisely the specification of a problem to be solved‚ and converts it into a series of instructions for a computer. It is not

Essay Object oriented programming was developed because limitation was discovered in earlier approaches to programing. The evolution to the object oriented programming is based on the following previous languages. Evolution in computer programming languages: In the earlier time‚ at the beginning of programming the “Punch Card“ was used for the programming purpose. Then with the passage of time human tried to work on the binary digits called “Machine Language”. 1. Machine Language In the machine
