2.1 CONCEPT OF CODING

Dear students, have you ever thought about the games you play, either online or on your
mobile?

Have you thought about who developed them and how? What happens behind it?
Definitely, some process/functioning must be there to do all these developments. You know

a computer is an electronic device and it works on the basis of instructions written by
someone. These instructions are written in special languages which are easily understandable
by computers as well as humans. These languages are known as Programming languages.

To develop games and other beneficial programs, one needs to learn computer programming
language. Some of the popular programming languages are Python, C#, C++, Java etc.

Coding is the process of writing code (instructions) in a programming language to resolve
some problem/ create games / developing software/ creating websites etc.

Before going into the details of coding, let’s take an activity where you are planning to celebrate
a birthday party with your friends. Write the steps for the preparation of the party.

1. Invitation
2. Order a Cake
