Imagine you're planning a road trip. To ensure everything goes smoothly, you need to plan
each step — from choosing the route and booking accommodation to packing your bags and
preparing meals. Each task needs to be done in a specific order to ensure a successful trip, much
like how a computer program follows a series of instructions to achieve a goal.
A program is a set of instructions written in a particular programming language to complete a
task. It is the backbone of software, enabling computers to perform various tasks and allowing
users to fully utilise computing devices. The process of planning the steps and writing the
instructions is known as programming, and the language used to write these instructions is
called a programming language.
Common programming languages include Python, C++, Java, BASIC, Scratch, and others.
INTRODUCING SCRATCH
Scratch is an easy-to-learn programming language created by the Lifelong Kindergarten Group
at the MIT Media Lab. It has a fun and interactive visual environment that helps beginners learn
programming, solve problems, and be creative.
Scratch is easier to use than many other programming languages because:
It is great for making games, animations, interactive stories, and other fun programs.
You can give commands using visual blocks, so there is no need to remember complicated
instructions.
Scratch uses a block-based visual programming interface where users drag and drop command
blocks to create scripts.
The blocks are colour-coded and designed like puzzle pieces, making it easy to arrange them
logically.
