What is Computer Programming?

Computer Programming is a step by step process of designing and developing various sets of computer programs to accomplish a specific computing outcome. The process comprises several tasks like analysis, coding, algorithm generation, checking accuracy and resource consumption of algorithms, etc. The purpose of computer programming is to find a sequence of instructions that solve a specific problem on a computer.

Computer Programming is very easy if it is appropriately managed. There are many computer programming languages available so finalizing the right programming language is not an easy task.

Basic of programming

English is the most popular and well-known Human Language. The English language has its own set of grammar rules, which has to be followed to write in the English language correctly.

Likewise, any other Human Languages (German, Spanish, Russian, etc.) are made of several elements like nouns, adjective, adverbs, propositions, and conjunctions, etc. So, just like English, Spanish or other human languages, programming languages are also made of different elements.

Just like human languages, programming languages also follow grammar called syntax. There are certain basic program code elements which are common for all the programming languages.

Most important basic elements for programming languages are:

  • Programming Environment
  • Data Types
  • Variables
  • Keywords
  • Logical and Arithmetical Operators
  • If else conditions
  • Loops
  • Numbers, Characters and Arrays
  • Functions
  • Input and Output Operations

Applications of computer programming languages

Python
 Web and Internet Development, Scientific and Numeric applications, Desktop GUIs, Business applications. It is widely used in AI and Machine Learning space.
Java Mostly used for developing Android apps, web apps, and Big data.
R
 Data Science projects, Statistical computing, Machine learning
Javascript
 JavaScript usage include web/mobile app development, game development, and desktop app development.
Swift Swift is a specially designed language which works with Apple’s Cocoa and Cocoa Touch frameworks to create all types of iOS apps.
C++ C++ is widely used in Game Development, Advance Computations, and Graphics Compilers
C# Widely used in Enterprise Cross-Applications Development, Web Applications
PHP Web Development, Content Management Systems, eCommerce Applications
SQL Used in Any Database
Go Console utilities, GUI applications, and web applications

How to choose a programming language?

Computer programming is a set of written instructions that the computer follows. These instructions can be written in various languages. Each programming languages have their unique ways of organizing the commands which are called syntax.

Multiple programming languages can help you solve the same programming problem. However, you need to select a language that you feel is relevant to perform your task. If you decide that a language does not suit your business requirement, you can always move on to a new language. Your skill in the chosen language will also be a deciding factor. Expected software system response time, a number of simultaneous users, security, maintains, compatibility with web, mobile, devices are few other factors to consider while choosing a language.
