Learn Programming For Free

Programming, also known as coding, is the process of creating a set of instructions that tell a computer how to perform a specific task. These instructions, called programs, are written in a language that the computer can understand and execute.

Welcome to our journey into the world of programming! This article will guide you through the essentials of learning how to code, from understanding what is programming, to exploring its various aspects including handling numbers, text, patterns, geometry, date and time, and creating menu-driven programs. Whether you’re a beginner or an experienced coder, there’s something for everyone. Let’s dive in!
