History of C

Chapter:1

There is a similarity between the human actions and the way a computer functions.Nicholas Wirth the inventor of computer language Pascal used to Say A program is equal to Algorithm + Data.

By Describing the Step-by-Step process is called as Algorithm

By representing the various steps in the form of Pictorial representation is know as Flowchart.

Algorithm: The term Algorithm is very popular in computer literature. An Algorithm is also called as Pseudo code. It is very simple to understand, in fact we all are perform hundreds of algorithms in our daily life without realizing it.

Algorithm is step-by-step method of performing any task. When we break up big task into smaller steps, what we actually do is create an algorithm. In algorithm each step is called as Instruction.

Example of Algorithm for making Tea.

Begin
Boil Water.
Put tea powder in the kettle.
Pour Boiled water in he kettle.
Wait for Three minuets.
Boil Milk.
Put Boiled Milk in cup.
Add sugar to the cup.
Empty the kettle in the cup.
Stir the cup with spoon.
End.

Flow chart:

There is another way to write the steps involved in any process.This is by making use of various symbols.The symbols from a diagram that represents the steps in a picotial fashion similar to an algorithm. This is also very easy to understand.Such diagram is called Flow chart. In its simplest form, a flow chart consists of a series of rectangles connected each other by others.

History of C Language

Before C Language we have some more languages those are also having same principles.

ALGOL (Algorithm oriented language) developed in 1960 by International Group.
BCPL (Basic combine programming language) developed in 1967 by Martin Richard.
B language was developed in 1970 by Ken Thompson.
After Many years many of the features derived form B Language that's why name has C.
C Language Was developed by Dennis Ritchie in 1972.
C language was created for specific purpose i.e designing the unix operating system.
After 7-8 years C++ came into world that was the first Object Oriented Programming language.
