Description
C Language Overview
This chapter describes the basic details about C programming language, how it emerged,
What are strengths of C and why we should use C.
The C programming language is a general purpose, high level language that was
originally developed by Dennis M. Ritchie to develop the UNIX
operating system at Bell Labs. C was originally first implemented on the DEC PDP
11 computer in 1972.
In 1978, Brian Kernighan and Dennis Ritchie produced the first publicly available
description of C, now known as the K&R standard. The UNIX operating system, the C compiler, and essentially all UNIX applications programs have been written in C.
The C has now become a widely used professional language for various reasons.
Easy to learn
Structured language
It produces efficient programs.
It can handle low level activities.
It can be compiled on a variety of computer platforms.
Facts about C
C was invented to write an operating system called UNIX.
C is a successor of B language, which was introduced around 1970.
The language was formalized in 1988 by the American National Standard
Institute.(ANSI).
The UNIX OS was totally written in C by 1973

Design & Analysis of Algorithm
Trending!
We study data structures so that we can learn to write more efficient programs. But
why must programs be efficient when new computers are faster every year? The
reason is that our ambitions grow with our capabilities. Instead of rendering efficiency needs obsolete, the modern revolution in computing power and storage capability merely raises the efficiency stakes as we computerize more complex tasks.
The quest for program efficiency need not and should not conflict with sound
design and clear coding. Creating efficient programs has little to do with “programming tricks” but rather is based on good organization of information and good algorithms. A programmer who has not mastered the basic principles of clear design
is not likely to write efficient programs. Conversely, “software engineering” cannot
be used as an excuse to justify inefficient performance. Generality in design can
and should be achieved without sacrificing performance, but this can only be done
if the designer understands how to measure performance and does so as an integral
part of the design and implementation process. Most computer science curricula
recognize that good programming skills begin with a strong emphasis on fundamental software engineering principles. Then, once a programmer has learned the
principles of clear program design and implementation, the next step is to study the
effects of data organization and algorithms on program efficiency
