What is C? Where it is used ?

About C language:- C is mother language of all programming language. It is system programming language. It is procedure-oriented programming language. It is also called mid level programming language. C was developed by Dennis Ritchie at Bell Laboratories in 1972. Most of its principles and ideas were taken from the earlier language B, BCPL and CPL. CPL was developed jointly between the Mathematical Laboratory at the University of Cambridge and the University of London Computer Unit in 1960s. CPL (Combined Programming Language) was developed with the purpose of creating a language that was capable of both machine independent programming and would allow the programmer to control the behavior of individual bits of information. But the CPL was too large for use in many applications. In 1967, BCPL (Basic Combined Programming Language) was created as a scaled down version of CPL while still retaining its basic features. This process was continued by Ken Thompson. He made B Language during working at Bell Labs. B Language was a scaled down version of BCPL. B Language was written for the systems programming. In 1972, a co-worker of Ken Thompson, Dennis Ritchie developed C Language by taking some of the generality found in BCPL to the B language. The original PDP-11 version of the Unix system was developed in assembly language. In 1973, C language had become powerful enough that most of the Unix kernel was rewritten in C. This was one of the first operating system kernels implemented in a language other than assembly. During the rest of the 1970's, C spread throughout many colleges and universities because of its close ties to UNIX and the availability of C compilers. Soon, many different organizations began using their own versions of C Language. This was causing great compatibility problems. In 1983, the American National Standards Institute (ANSI) formed a committee to establish a standard definition of C Language. That is known as ANSI Standard C. Today C is the most widely used System Programming Language. Application areas of C language where C language is used: 1. C language is used for creating computer applications  2. Used in writing Embedded softwares 3. Firmware for various electronics, industrial and communications products which use micro-controllers. 4. It is also used in developing verification software, test code, simulators etc. for various applications and hardware products. 5. For Creating Compiles of different Languages which can take input from other language and convert it into lower level machine dependent language. 6. C is used to implement different Operating System Operations. 7. UNIX kernel is completely developed in C Language.

C is general purpose programming language. Most of the time C is used for developing embeded system softwares like boot loader, drivers, embeded applications. C is also used to create PC Operating Systems, frameworks and softwares. C is powerful tool for core development for protocols, network programming, threading, generic engines. read less

C is a procedural programming language, means in C their is a procedure for writing any program or we can say that for writing any C code their is an algorithm for it. Its uses are not limited it is used in embedded systems, small windows applications, designing of red lights etc. To learn any language first we need to learn its alphabets similarly in programming you first have to master C because it covers all the basics of programming. read less

Communication is the process of transfer the data between Object. that is possible through natural languages. To communicate with the machine(to perform complex operations), we need to pass instructions in machine code. It is not possible to define instructions in machine code Using high level language(C, C++ ....), we can define instruction set in a easy way, Later these instruction must be converted by compiler for communication. read less

In simple c is a programming language(middle-level) that uses procedure oriented programming methodology to program. It is one of the most used programming language and it have made a great impact in all its successive programming language, as many of of them have c-like syntax. Many languages, Operating System and other system tools, Game Engines have been built over C and C++. They are being used in embedded industry as they are closer to machines than any other trending programming language. read less
