It is the process of providing instructions to computers for the completion of certain tasks, and it is the foundation of “software engineering”, “website designing”, “data analysis”, “machine learning”, and other related disciplines.

This article will give the reader good background information on programming including the basics of programming, the significance, and how to start programming.

Introduction to Programming

What is Programming?

It is also known as coding which involves creating code that outlines a series of instructions for a computer to follow to address a definite difficult. These are written in programming languages, which are special languages that programmers use to give instructions to computers.

Importance of Programming

Automation

Programming helps reduce the workload and time taken to do a particular task by automating it.

Problem-Solving

It also enables one to develop critical thinking skills since most programs require one to solve problems by compartmentalizing them.

Career Opportunities

Computer programming fluency provides extensive job prospects in different fields such as information technology, banking and finance, health care and many others.

Innovation

It is the core of developments in technology and encompasses the creation of AI, machine learning, robotics and other emerging technologies.

Basics of Programming

Syntax: Syntax refers to the rules of the language, and every programming language has this; it defines what is accepted as a correctly structured program in that language.

Variables: A variable is a data item that can be manipulated by the program and the data stored in it can be accessed.

Control Structures: These are loops; “for” and “while” and “conditionals”; “if” and “else”.

Functions: Functions are blocks of code that are used to do a particular task and can be used any number of times.

Getting Started with Programming

• Choose a Language: Newcomers are encouraged to start with a language that is easy to learn such as Python because of its simplicity and the availability of many people who can help out.
• Online Resources: Use web resources such as Techprofree , Codecademy, Coursera and Khan Academy to find tutorials and courses.
• Practice: Learn programming, build your portfolio and begin with simple projects and then move up to the challenging ones.
• Join a Community: Interact with other learners and other experienced programmers via forums, coding boot camps and local meetups.

Programming Paradigms

Programming paradigms are different ways or approaches to programming. These paradigms provide diverse possibilities for categorizing and arranging code to make it more effective for certain/specific purposes (needs).

Procedural Programming

This paradigm involves writing down sequences of instructions to tell the computer what to do at every stage. It is based on the procedure calls which mean that the code is divided into functions. “C” is one of the best examples of procedural language.

Object-Oriented Programming (OOP)

In OOP, data is required to be grouped into objects that are based on the classes that come with data as well as functions. It is required for huge multi-programmed systems where code modularization and reusability are crucial. Some existing languages include Java, C++, and Python, few of which support OOP. This paradigm is especially useful when developing systems that replicate real-world artifacts or things.

Functional Programming

It defines computation as the calculation of mathematical functions and does not involve changing state as well as mutable data. Two of the functional programming languages most commonly used are Haskell and Scala, they are typically applied in applications that involve large volumes of data because stateless operations are beneficial in preventing and eliminating errors, and the program will not behave unpredictably.

Every problem is unique, and having several paradigms means that a programmer has all the tools he needs to solve a particular problem. For instance, while procedural programming can be used in creating simple scripts, OOP is used when creating larger applications that could be scaled and needed in different parts of an application.

Popular Programming Languages

• Python is an easy and quite universal programming language used in web development, data analysis and scripting.
• Crucial in web development, JavaScript is used to develop internet applications that are interactive and is compatible with all the current browsers.
• Java is a rock-solid object-oriented language used for developing business and Google’s Android applications.
• C++ is the upgraded version of C and is used for system/software development and game programming.
• Ruby is renowned for its simplicity and high productivity, making it a popular choice for web development, primarily through the “Ruby on Rails” framework.
