2. C programming language
Ø C programming language features were derived from an earlier language called
“B” (Basic Combined Programming Language – BCPL).
Ø
Ø The C programming language is a structure oriented programming language,
developed at Bell Laboratories in 1972 by Dennis Ritchie.
Ø
Ø C was invented to write an operating system called UNIX.
Ø
Ø Today C is the most widely used and popular System Programming Language.
Ø In 1983, the American National Standards Institute (ANSI) established a
committee to provide a modern, comprehensive definition of C. The resulting
definition, the ANSI standard, or “ANSI C”, was completed late 1988.

3. Why use c
Ø C language is a middle level language so its easy to
compile and easy to understand by the programmer.
Ø High protability,high protection and much higher
efficiency(how to use least resourses as possible)
Ø C language is a subset of c++.
Ø Ready access to the hardware when needed.
Ø The ease with which applications can be optimised by
hand-coding isolated procedures.

are some of the features of C language.
Reliability
Portability
Flexibility
Interactivity
Modularity
Efficiency and Effectiveness
6. Definition of c
C programming is considered as the base for other
programming languages, that is why it is known as
mother language.
v It can be defined by following ways:
Ø Mother language
Ø System programming language
Ø Procedure-oriented programming language
Ø Structured programming language
Ø Mid level programming language
7. Key points to remember.
The C language is a structure oriented
programming language developed by Dennis
Ritchie.
The C language is belonging to middle level
programming language.
Operating system programs such as Windows,
Unix, Linux are written in C language.
C89/C90 and C99 are two standardized editions
of C language.
C has been written in assembly language.
