Origin of C Language
History of C Language
3. What is C Programing?
C is a high-level and general purpose programming
language that is ideal for developing firmware or
portable applications. Originally intended for writing
system software, C was developed at Bell Labs by
Dennis Ritchie for the Unix Operating System (OS) in
the early 1970s.
4. Why C language is so Important?
C language cases:
Oracle is written in C
Core libraries of android are written in C
MySQL is written in C
Almost every device driver is written in C
Major Part of web browser is written in C
Unix Operating system is developed in C
C is the word’s most popular programming language
5. Why C language is so Important? (cont..)
For a student point ofView:
C is important to build programing skills.
C covers basic features of all programming
C is also helpful for Campus recruitment process
C is the most popular language for hardware
dependent programs
6. The Creator of C language
Dennis MacAlistair Ritchie
was an American computer
scientist. He created the C
programming language. He also
created The Unix operating
system with his long time
colleague Ken Thompson.
Dennis Ritchie
1941-2011
Father of C and UNIX

Origin of C Language
8. Origin of C Language (cont..)
BCPL and B are "type less" languages whereas C provides
a variety of data types.
In 1972 Dennis Ritchie at Bell Labs writes C and in 1978
the publication ofThe C Programming Language by
Kernighan & Ritchie caused a revolution in the computing
world.
9. History of C Language
Evolved from two previous languages – BCPL, B
BCPL (Basic Combined programming language) used for
writing OS & compilers
B used for creating early versions of UNIX OS
Both are “typeless” language
C language evolved from B (Dennis Ritchie – Bell labes)
10. Algol programming language
Algol is a computer programming language
Developed in 1958.
Named for the algorithmic process of definition of a
programming problem.
Short for Algorithmic Language.
Uses words to bracket blocks and was the first to use
begin end pairs.
11. BCPL
Full form: Basic Combined Programming Language.
Developed in 1996.
Developed by Martin Richards
Its having high portability.
BCPL is the successor to the CPL programming language.
12. B
Developed in 1969
Designed by D. M. Ritchie and K. L.Thompson
Developed at Bell Labs
B was derived from BCPL
Designed for primarily non-numeric applications.
