Introduction: Computer is a machine which cannot understand our languages. It understands only electric signals which are on and off (0 and 1). In order to make the computer do something we need to give it some instructions which are understood by the computer. It is difficult to instruct a computer in only (0 and 1) machine language which is difficult for human. For making the programming is easy assembler is designed. Now human can instruct a computer in assembly language (near to English language) which is easier for human to understand. This assembly language is then converted to machine language by assembler. Further more, to make more easier programming high level languages are designed. Nowadays there are so many High level languages such as C, C++, C#, Turbo-C, Java, Pascal, etc. Among these programming languages C is the most popular and prime programming language. Now, we will learn some C programming.
