INTRODUCTION of c:
C is a general-purpose,Structural language.It is associated with the UNIX
operating system where it was developed, since both the system and most of the
programs are written in C only. The main features of C is bridging the gap between
machine language and the more conventional high-level languages. This flexibility
allows C to be used for systems programming (e.g., for writing operating
systems) as well as for applications programming(e.g.,for writing a program to
bill customers).
History of c:
C was originally developed in the 1970s by Dennis Ritchie at Bell Telephone
Laboratories, Inc. (now a part ofAT&T).many of the ideas of C comes from Two
languages called BPCL and B, which were also developed at Bell Laboratories.
BCPL and B are ``typeless'' languages. By contrast, C provides a variety of data
types. By the mid 1980s, the popularity of C had become widespread. Moreover,
many commercial software products that were originally written in other languages
were rewritten in C in order to take advantage of its efficiency and its portability.
