Introduction:
C is a structured programming language. Every C Program is made of one or more pre-processor commands, a global declaration section and one or more functions. It is a high level language that allows the (user) programmer to concentrate on the problem hand and not worry about the machine that the program will be using C was originally developed by Denis Ritchie between 1969 and 1973 at Bell labs and used to re implement the UNIX Operating System. A programmer can create many game applications, audio, video programs through C programming language. Often C Language is a medium language but most of the programmer treats as high level language. It is mainly used to write Operating systems. It includes low level access to memory, simple set of keyword. Many languages have borrowed syntax/ features directly or indirectly from C language. Like syntax of JAVA, PHP, JavaScript and other language is mainly based on C language.

C is a procedure oriented programming, which follows the top down approach in program design. It does not have data hiding options. C Languages is much focused on the data hence on functions. C language doesn’t have any such functionality. It follows whatever steps are written in a function.

History of C language

Language Year Developed by
ALGOL 1960 International Group
BCPL 1967 Martin Richard
B 1970 Ken Thompson
Traditional 1972 Dennis Ritchie
K & Rc 1978 Kernighan & Dennis Ritchie
ANSIC 1989 ANSI Committee
ANSI/ISOC 1990 ISO Committee
C99 1999 Standardization Committee
C11 2011 Standardization Committee

C like must modern language is derived from ALGOL the first language to use a block structure. ALGOL is the way for the development of structured programming concepts during 1960’s. In 1967, Martin Richard developed a language called Basic Combined programming language or BCPL. During 1970 Ken Thumpson followed B, was used to develop the first version of UNIX one of the popular Operating System. Finally, in 1972 Dennis Ritchie developed C, Which tool many concepts from ALGOL.

Dennis Ritchie and Brain Kernighan published the first edition “ The C Programming Language” and commonly know as K &PC during 1978. The American National Standards Institute  (ANSI) established a committee to provide definition of C was completed late 1988. C90 Standard- First Standardized specification for C language was developed by the ANSI in 1990 C99 Standards- Next revision published in 1999 the introduced new features like advanced data types and other changes.

Features of C Programming language:

C language is one of the powerful language

  • Reliability : The resultant (output) is always be reliable through C programming language
  • Portability
  • Flexibility
  • Interactivity
  • Modularity
  • Efficiency and Effectiveness

Uses of C Programming Language

It is used for developing system applications that forms a major portion of Operating systems such as Windows, UNIX and LINUX.

  • Database Systems
  • Graphics packages
  • Word Processors
  • Spread Sheets
  • Compilers and Assemblers
  • Interpreters
