Introduction of C
C is a structured programming language, able to work with all most all field or applications for
general as well as scientific purpose. C is also identifying as MLL (Middle level language),
because of its symbolic constant behavior. We can say it used some syntactical and
grammatical rules which must be followed by users. All programs are created by some extra
symbols and text and these text and symbols have their own meaning inside the C language. So
it is necessary for users to follow the sequence of rule after follow the symbols and text in their
own format. This is the reason to call it as MLL. In C language user can create multiple small unit
of program (called procedure/thread) to combine them in a large program. All small programs
called procedure have a proper structure to declare them as structured programming language.
C is also defined as general purpose language which means it worked in scientific as well as
commercial both fields together. C is a strongest typed language, used to develop any kind of
system software and driver software of system. All the keywords of C language are accessed
only by lower case, because it is a case sensitive language where the fixed type of data and
functions are always produce in lower case.
History of C language:
The entire era when C was developed, is called as evaluation of programming language. Before
the development of C, some different programming languages were used in market, such as
COBOL, FORTRAN, and ALGOL etc. In this time some languages are worked on commercial and
some are worked on scientific field but there were no common language for both fields.
For example FORTRAN worked for scientific purpose and COBOL worked for commercial field.
FORTRAN was developed by John Backus and his team at IBM co. for its 701 computer, in 1957.
It was developed by a retired navy commander and mathematician named Gross hopper in
1951. This language was later worked at 1959 – 1960 by the committee of conference on data
system language (CODSYL) as a joint effort of computer user manufacturer of USA government.
In this time, another language was introduced in commercial application but later it worked on
educational field named BASIC which was define by Thomas Kurtz and implemented by John
kamney at Dourth Mouth college, USA in 1964.
