1.1 Introduction to C Language :-

Introduction

❖ C is a structured general purpose programming language. It was developed to rewrite the

Unix operating system. Earlier, the unix operating system was written in B language. Almost

the entire Unix operating system and its running programs are written in the C language

itself.

❖ B language was written by Ken Thompson in Bell Laboratories in 1970. B was a

type less language. That is, there was no concept of data types in B. B language could not

achieve much popularity.

❖ C language was developed by Dennis Ritchie in bell laboratories in 1972. C is a

type full language. C language provides many data types.

❖ C was a very short and simple language. So in a short time it became very popular

and it started using other computer scientists as well.

❖ There is no shortage of popularity in the C language. Before learning any other

programming language, C language is taught. Because whatever language programming

language (C ++, Java, PHP, C # etc) came after C language, they have adopted syntax of C

somehow.
