ABOUT THE TUTORIALComputer Prgramming TutorialComputer programming is the act of writing computer programs, which are a sequence of instructionswritten using a Computer Programming Language to perform a specified task by the computer.Computer Programming is fun and easy to learn provided you adopt a proper approach. This tutorial willtake you through simple and practical approach while learning computer programming.AudienceThis tutorial has been prepared for the people who are struggling to learn computer programming butthey are unable to learn it due to lack of proper guidance and approach. I'm confident that aftercompleting this tutorial you will be at a level where you can code in C Programming language and willhave basic understanding of Java and Python programming languages as well and you can continuefurther from that point onwards.If you are completely new to Computer Programming, then my recommendation is to read this tutorialtwice or even thrice. First reading will not give you much idea, but during your second reading, you willstart grasping most of the concepts and you will enjoy while writing great computer programs.PrerequisitesI do not expect much from your as pre-requisites to teach you computer programming but I assume thatat-least you have basic knowledge about computer and its peripherals like keyboard, mouse, screen,printer, etc. If you know more than this like word editor, good typing speed, internet search, etc., then itwill help you a lot while doing your computer programming.Copyright & Disclaimer Notice Allthe content and graphics on this tutorial are the property of tutorialspoint.com.

1CHAPTERProgramming - OverviewIassume today is your first day when you heard about computer programming. You are curious to know whatexactly is computer programming? Before you understand what is computer programming, you need to understandwhat is computer program?I'm making an assumption that you know a little about what is computer and how to use it for Internet browsing,Exploring Facebook or Checking e-mail using Gmail, etc.What is Computer Program?A computer program is a sequence of instructions written using a Computer Programming Language to perform aspecified task by the computerI assume, you did not understand what I have written about computer program but let’s see two important terms,which I have used in the above definition: Sequence of instructions Computer Programming LanguageTo understand these terms, consider a situation when someone asks you about how to go to a nearby KFC. Whatexactly do you do to tell him the way to go to KFC?You will use Human Language to tell the way to go to KFC something as follows:First go straight, after half kilometer, take left from the red light and then drive around one kilometer and you will findKFC at the right.Here, you have used English Language to give several steps to be taken to reach to KFC. If they will be followed inthe following sequence, then you will reach KFC:1.2.3.4.5.Go straightDrive half kilometerTake leftDrive around one kilometerSearch for KFC at your right sideNow, try to map the situation with computer program. Above sequence of instructions is actually aHumanProgram written in English Language, which instructs on how to reach to KFC from a given starting point. ThisTUTORIALS POINTSimply Easy Learning
same sequence could have been given in Spanish Language, Hindi Language, Arabic or any other human languageprovided someone, who is asking about the way, knows about such languages.Now, let's go back and try to understand about a computer program, which is a sequence of instructions written in aComputer Language to perform a specified task by the computer. Following is a simple program writtenin Python programming Language:print "Hello, World!"Above computer program instructs computer to print "Hello, World!" on computer screen. A computer program is also called a computer software,
