- 2. INTRODUCTION The C programming language is a structure oriented programming language, developed at Bell Laboratories in 1972 by Dennis Ritchie C programming language features were derived from an earlier language called “B” (Basic Combined Programming Language – BCPL) C language was invented for implementing UNIX operating system In 1978, Dennis Ritchie and Brian Kernighan published the first edition “The C Programming Language” and commonly known as K&R C 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.
- 4. USES OF C PROGRAMMING LANGUAGE: The C programming language is used for developing system applications that forms a major portion of operating systems such as Windows, UNIX and Linux. Below are some examples of C being used. Database systems Graphics packages Word processors Spreadsheets Operating system development Compilers and Assemblers Network drivers Interpreters
- 5. C LANGUAGE IS A STRUCTURED LANGUAGE: Structure oriented language: In this type of language, large programs are divided into small programs called functions Prime focus is on functions and procedures that operate on the data Data moves freely around the systems from one function to another Program structure follows “Top Down Approach” Examples: C, Pascal, ALGOL and Modula-2
- 6. OBJECT ORIENTED LANGUAGE: In this type of language, programs are divided into objects Prime focus is in the data that is being operated and not on the functions or procedures Data is hidden and cannot be accessed by external functions Program structure follows “Bottom UP Approach” Examples: C++, JAVA and C# (C sharp)
- 7. KEY POINTS TO REMEMBER IN C LANGUAGE: 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.
