Bella visits Quba to showcase a computer game she created, sparking Quba's curiosity about programming. Bella explains that programming allows for the creation of applications like games and drawing tools, emphasizing the importance of computer programming knowledge. Various programming languages, such as Python and Java, are introduced as essential for writing the source code for applications.

Next Day, Bella thought to visit Quba’s house because she wanted to
show something exciting to Quba. So she took her computer and
went to the tree where she met Quba for the first time. She could
also see Quba’s friends flying around in curiosity to know what is

Today, I will show you a game which I created
for you!
Game? yeaaee….I love playing games ..and You
created a game? Wow Bella! I am amazed. Is
it possible to create a game by ourselves??
Yes, not only games, whatever application we
use in computer are created by instructing
computer. And giving instruction to
computer is called programming
Waaw amazing …..Computer programming
makes it all possible?.…..so what else can we
do using programming?
Yes, exactly. You really are a quick learner.
I will teach you more about programming
…before we start playing
Waaw amazing …..so we can create games
and many other things with the help of
computer programming??
You are familiar with paint application,
right?. With the paint application you can
draw many pictures. Do you ever think how
these applications are created? Now you
have the answer....They are all created by
computer programming. So we can also
create such applications, for that we should
have knowledge in computer programming.

Source Code
A computer program is also called
code or source code. So for any
application there will be some
source code written in some
language such as java, python, php
etc
What is 10 + 25??
Programmers
People who write programs are called
programmers. Their job is to create
software by writing programs. Yes,
every software we use now are the
results of their Job and created by
writing programs.
Programming languages
We know programming means
giving instructions to computer. But
we must give instructions to computer
in a language that computer can
understand. These languages are
called programming languages. Some
programming languages are python,
java, php, dotNet, C,C++
