Program and Programming

The collection of instruction written in sequence according to a set of rules is called operating system program.

The software which is used to write programs is called as programming language.

All the programming languages are the application software which has been created for the use of users. There is no any limitation of work in any programming language we can do as much work in any language as we can think but any work can be performed through language by writing the program our self.

The method of writing program in any language is called programming technique. 

There are three programming technique developed till now.

    1.   Linear programming technique: -     This technique provides the facilities to write whole program code in single page or module either the program code is too big or too small.

The main purpose of linear technique was to learn “How to Program”. So, this technique is basically used to write small programmes only.

The software development was very complicated through linear programming technique because testing and debugging become very difficult.

Ex- BASIC, LOGO, FORTRAN, COBOL, etc.

BASIC : -  Beginner All Purpose Symbolic Instruction Code.

LOGO : - Logical Oriented Graphic Oriented.

FORTRON : - Formula Translation.

COBOL : - Common Business Oriented Language.

    2.   Structured programming technique: -     This technique provides the facility to divide the whole program in several modules. Each module should perform only one task and each module can be linked together according to our need to perform a single task.

This technique simplifies the software development process because the testing and debugging of the program become very easy for the programmers. So, the ratio of software development got increased after the invention of this technique therefore this technique is called as the basic technique in programming area.

Ex: - C, C++, PASCAL, ADA, VB 6.0, etc.

    3.   Object oriented technique: -     This is new technique which introduced some advanced feature with programming language. It introduced the concept of “CLASS”. So, all the feature of object oriented technique can be implemented by using “CLASS” only.

Those programming language which supports the use of “CLASS” are called as object oriented programming language.

Although it is a new programming technique but irs programming style is still dependent on structured programming technique.

Ex: - C++, JAVA, C#, .NET (VB.NET, ASP.NET, C#.NET, etc), etc.
