<h3><strong>Introduction and history of c</strong></h3>
<p>C programming is considered as the base for other programming languages, thats why it is known as "mother
language".<br>C is a middle-level procedure oriented programming language, used in general purpose programming, developed by Dennis Ritchie at AT&T Bell labs, USA between 1969 and 1973. </p>
<ul>
<li class="list-s">“C” became popular because of its reliability, simple and easy to use. </li>
<li class="list-s">ALGOL 60 was developed and did not become popular because it was too general and too
abstract. </li>
<li class="list-s">They developed “CPU” (Combined Programming Language).</li>
<li>It can be compiled on a variety of computer platforms.</li>
<li class="list-s">Next as it could not come up to make ALGOL 60 better one they moved to “BCPL” (Basic
Combines Programming Language. Developed by martin Richard Cambridge University). </li>
<li class="list-s">. At the same time a language called “B” written by ken Thompson at AT & T‟S. Bell
laboratories as a further simplification of BCPL. </li>
</ul>
<h5>C Programming Language Version History:</h5>
<ul>
<li>1972- Traditional C- Denis Richie</li>
<li>1978- K & R C - Kernighan and Richie</li>
<li>1989- ANSI C - ANSI Committee</li>
<li>1990- ANSI/ISO C - ISO Committee</li>
<li>1999- C 99 - Standardization Committee
</li>
</ul>
<h5>Importance of C language: </h5>
<ol>
<li>In 1988, the American National Standards Institute (ANSI) has formalized the C language.</li>
<li>C was invented to write UNIX operating system.</li>
<li>UNIX is considered to be one of the most robust and secured operating system. C was used to write it, So
C is very efficient that it can be used to create an OS.</li>
<li>C is a successor of ‘Basic Combined Programming Language’ (BCPL) called B language.</li>
<li>Linux OS, PHP and MySQL are written in C.</li>
<li>C has been written in assembly language.</li>
<li>C has high flexibility means a function can be written and can be used so many times at so many places.
It increases the modularity.</li>
<li>Rich set of library support.</li>
<li>The C language is used for developing system applications that forms a major portion of operating
systems such as Windows, UNIX and Linux. Below are some examples</li><strong> where C language is being
used:</strong><br>
<ul>
<li class="">Database systems</li>
<li class="">Graphics packages</li>
<li class="">Word processors</li>
<li class="">Spreadsheets</li>
<li class="">Operating system development</li>
<li class="">Compilers and Assemblers</li>
</ul>
