Introduction To Programming Language WHAT IS PROGRAMMING? “COMPUTER PROGRAMMING IS THE ART OF MAKING A COMPUTER DO WHAT YOU WANT IT TO DO” A program is aaa collection of instructions written in any programming language. They tell a computer how to perform a some task. It is just like a recipe which tells us how to prepare a particular dish and also describes all its ingredients and the steps to follow. Programming is also very similar in concept. WHAT IS LANGUAGE? Language is the medium of communication and sending/receiving thoughts between two people. For communication, a medium is required which can be understand from both the sides and that medium is known as a language. Many different languages are used across the world but the motive behind them is to transfer the messages or information. Alike computer also has its many languages which are developed according to the need. We know that computer is an electronic machine and it is not able to think like humans nor it has any of his own language through which we can establish communication with it. Therefore to use computer we need a language in which we can give instructions in human readable form and computer reads it in its own machine language and returns back the information needed in again human readable language. Levels of Computer Languages Computer mainly unserstand only one language that is machine language. Then also we can categorized them into three: 1. Low level language It is also known as machine language. In this language coding can be done according to binary only so that only those who understand the internal architecture of machine can use this language. Programs written in binary language are executed only on that system on which ... ... middle of paper ... ...is one of the most popular programming languages and there are very few computer architectures for which a C compiler does not exist. C has greatly influenced many other popular programming languages, most notably C++, which originally began as an extension to C. HISTORY OF C • Invented in 1972 at AT & T Bell laboratories by Dennis Ritchie. • Initially it was designed for programming in the Operating System called UNIX. • It is derived from the B language, which was written by Ken Thompson at AT & T Bell laboratories. • The B language was adopted from a language called BCPL (Basic Combined Programming Language), which was developed by Martin Richards at Cambridge University. • In 1982 a committee was formed by ANSI (American National Standards Institute) to standardize the C language. Finally in 1989, the standard for C language was introduced known as ANSI C.
