                  Suppose,  you  are  organising a  birthday  party.  You  need  to  make sure  everything  happens
                  smoothly, from sending invitations to arranging the cake, games, and music. Each step must
                  be followed to make the party a success, just like how a computer program follows a set of
                  instructions to achieve a result.
                  A program is a set of instructions written in a specific programming language to do a specific
                  task. It is the fundamental building block of software, enabling computers to perform a wide
                  range of tasks and enabling the users to utilise the capabilities of computing devices for various
                  purposes. The process of deciding the steps and writing instructions is called programming and
                  the language in which the instructions written is called programming language.
                  The programming languages that we can use to do our work can be Python, C++, Java, BASIC,
                  Scratch, and many others.

                     INTRODUCING SCRATCH

                  Scratch is an easy-to-learn visual programming language developed by the Lifelong Kindergarten
                  Group at the MIT Media Lab. It has a playful and powerful interactive visual environment that
                  serves as a stepping stone into the world of programming for beginners to explore computational
                  thinking, problem-solving, and creativity.
                  Scratch is easier to use than most other programming languages because:

                     It is one of the best programming languages for making games, animations, interactive stories,
                     and other visually rich programs.
                     The commands are given using visual interactive tools, so there is no need to remember the
                     commands to do a task.
