What is computer programming?

Programming is the process of taking an algorithm and encoding it into a notation (sequence of instructions), so that computer can execute it. Simply, we can say programming is talking to computer in language of computer.

Why should I learn computer programming?

1. You will learn how to learn

   Programming is all about logic and problem solving. You will learn how to break down problems into small logical steps.

2. You will become more detail–oriented

   Learning to code requires attention to detail and precision. As you progress, you too will become more focused and detail-oriented

3. Improve your way of thinking

   Programming will certainly and drastically improves your way of thinking and will enhance your logical and reasoning ability. So, if you have interest in Mathematics, Reasoning, Logic or Problem solving then programming is here to be with you.

4. Enhance your career opportunities

   Knowing how to code can help anyone from content creators to office managers, and even basic programming skills can give the edge in an increasingly competitive world.

Can I Learn computer programming?

YES, you can learn computer programming and can write computer program. Everyone can learn computer programming, no matter what your background is. It’s a matter of interest and choice. There are lots of resources available where you can get started and learn computer programming.

What is a computer program?

A computer program is a sequence of instructions written using computer programming language to perform specified task(s) by the computer. A computer without a computer program is just a dump box.

Basics of Computer programming

Similar to human interface language, Computer Programming Language is also made of several elements. Before we learn any programming language, we should know all the elements of programming language.

1. Programming Environment
   • An integrated development environment (IDE) is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of a source code editor, build automation tools, and a debugger.
   • Build Automation is the process of automating software development
     • Compiling Source File
     • Packaging compiled files into compressed formats (binary code)
     • Producing Installer
     • Creating or Updating database schema or data
     • Running automated test
   • Why we require it?
     • An IDE is as important for a programmer as a calculator is for a mathematician
     • It will increase efficiency and productivity of programmer. (A programmer can spend more time thinking about real problems instead of wasting time in mundane task like managing dependencies, perfectly written syntax, managing ANT files, compiler parameters, setting testable environment, etc.)
2. Basic Syntax

   Syntax refers to the rules that specify the correct combined sequence of symbol that can be used to form a correctly structured program using a given programming language. Programmers communicate with computer through the correctly structured syntax, semantics and grammar of a programming language.

3. Data Types

   Data type in computer programming is a classification of data which tells compiler or interpreter how the programmer intends to use the data.

   There are five basic data types in computer programming

   1. int
   2. float
   3. double
   4. char
   5. void

    

4. Variables
   • A symbolic name for information
   • Variable’s name represents what information the variable contains
   • They are called variables because the represented information can change but the operations on the variables remain the same
5. Keywords
   • Keyword is a word that is reserved by a program because the word has a special meaning.
   • Keywords can be commands or parameters.
   • Every programming language has a set of keywords that can’t be used as variable names.
   • Keywords are sometime called reserved names.
6. Operators

   An operator in a programming language is a symbol that tells the compiler or interpreter to perform specific mathematical, relational or logical operation and produce final result.

   1. Arithmetic
      • Addition (+) Unary
      • Subtraction (-) Unary
      • Multiplication (*)
      • Division (/)
      • Modulo division (%)
