CONCEPT OF PROGRAMMING LANGUAGE:

In order to communicate with other human beings, one needs some language or a medium. In the same way for solving problems, a programming  language is required in order to communicate with the computer. A Programming Language is used to design and describe a set of instructions/actions for the computation that we wish to be executed by the computer.   First an algorithm is designed which solves the problem in question. In the next step, the algorithm is expressed in the form of a program. For this one should have a sound knowledge of some programming language. A program written in a particular Programming Language can control the behavior of  a computer and perform a designated task to generate the desired output for any given input.
