What is Programming?

Programming is the process of writing instructions that a computer can execute. These instructions are written in a programming language and are used to create software, websites, mobile apps, games, and more.

Key Concepts in Programming

1. Logic & Problem-Solving – Breaking down complex problems into step-by-step solutions.
2. Syntax & Semantics – Writing code that follows language rules (syntax) and makes sense logically (semantics).
3. Debugging – Identifying and fixing errors in your code.
4. Data Structures & Algorithms – Learning how to efficiently store and process data.
5. Version Control – Managing changes in your code using tools like Git & GitHub.

How to Start Programming

1. Learn the Basics of Computer Science

Understanding fundamental computer science concepts will help you in programming. Some key areas include:

• How computers work – Learn about hardware, operating systems, and networking.
• Data structures & algorithms – Lists, arrays, linked lists, recursion, sorting, etc.
• Computational thinking – Breaking problems into smaller parts.

💡 Where to Learn:

• CS50 by Harvard (Free)
• W3Schools
• Khan Academy - Computer Science

2. Choose a Beginner-Friendly Programming Language

Here are some great languages to start with:

Language	Best For
Python	General programming, AI, automation, web development
JavaScript	Web development, frontend & backend
C	Understanding low-level programming
Java	Enterprise applications, Android development
C#	Game development (Unity), Windows applications

✅ Recommendation: If you are new, start with Python or JavaScript because they have simpler syntax and are widely used.

3. Get Hands-On Experience

The best way to learn is by coding regularly.

• Use interactive coding platforms:

  • W3Schools
  • freeCodeCamp
  • Codecademy

• Work on small projects like:

  • A calculator
  • A to-do list app
  • A simple guessing game
