C History
- C is a general-purpose programming language initially developed by Dennis Ritchie that used the Unix Operating system between 1969 and 1973 at Bell Labs.
- C is the result of a development process that started with an older language called BCPL.
- BCPL was developed by Martin Richards, and it influenced a language called B, which was invented by Ken Thompson.
- In the summer of 1983 a committee was established to create an ANSI (American National Standards Institute) standard that would define the C language.
- The standardization process took six years (much longer than anyone reasonably expected).
- The ANSI C standard was finally adopted in December 1989, with the first copies becoming available in early 1990.
- The standard was also adopted by ISO (International Standards Organization), and the resulting standard was typically referred to as ANSI/ISO Standard C.
- Many later languages have borrowed directly or indirectly from C, including C#, D, Go, Java, JavaScript, Limbo, LPC, Perl, PHP, Python, and Unix's C shell.
What is C?
- C is a programming language developed at AT & T's Bell Laboratories of USA in 1972.
- It was designed and written by a man named Dennis Ritchie.
- C is a Middle Level language.
- C is thought of as a Middle-Level Language because it combines the best elements of High-Level Languages with the control and flexibility of Assembly Language (Low Level language).
High Level - Translator Required. Example:
Ada
Modula-2
pascal
COBOL
FORTRAN
BASIC
Middle Level - Combination of High Level and Low Level Language. Example:
Macro-assembler
Low Level - Translator not Required. Example:
Assembler
