C Course


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.
 Today, C is the most widely used and popular System Programming Language.
 Most of the state-of-the-art softwares have been implemented using C.
 Today's most ][popular Linux OS and RBDMS MySQL have been written in C.

Why to use C?

C was initially used for system development work, in particular the programs that make up the operating system. C was adopted as a system development language because it produces code that runs nearly as fast as code written in assembly language. Someexamples of the use of C might be:
 Operating Systems
 Language Compilers
 Assemblers
 Text Editors
 Print Spoolers
 Network Drivers
 Modern Programs
 Databases
 Language Interpreters
 Utilities
