Computer programming is a process that leads from an original problem formulation to executable programs. It involves writing instructions in a programming language that a computer can understand. While it is talked about widely now due to computing's role in everyday life, non-software companies also see value in people understanding programming for tasks like modeling, professional communication, and custom software development using languages like C and Python. For those new to programming, the presenter recommends starting with choosing an editor, exploring a language through simple programs, thinking through problems by designing solutions on paper, and then coding the designs. The path forward may involve fields like web development, systems programming, networking, or scientific computing.

2. Expected Layout of the Presentation
• What is it ?
• Why is it so talked about ?
• Why Non-Software-Based companies want people to know
programming?
• How should someone with no experience start it?

3. “I think everybody in this country should learn
how to program a computer because it
teaches you how to think.”
Steve Jobs

4. What is it?

5. • Computer programming is a process that leads from an original
formulation of a computing problem to executable computer
programs
• A Computer program is a sequence of instructions, written to
perform a specified task with a computer.
• Instructions, are part of a language, a Programming Language, that
is like a script, or dialect ( English, Hindi, Marathi ) that a Computer
can understand
• A computer understands at-least one programming language.
• Every programming language has its own grammar

6. Why is it so talked about ?

7. We all interact with computers in such a way that they’re no longer
this extra thing you do on the side
Computing is a vital part of what everybody does nowadays.
Not everyone wants to go out and create Web programs and write
the next Twitter
Having a base understanding of what happens behind the curtain can
be huge

8. Why Non-Software-Based
companies want people to know
programming?

9. 1. Modelling
• Modelling various phenomena is the trend today
• From modelling petroleum wells to modelling bacteria growth – a
vast spectrum
• Someone who knows core can model better
• Proficiency expected in Matlab/Mathematica similar languages

10. 2. Professional Communication
• If you are not the one doing the modelling, You would be the one
telling people what to model
• Most industries deal with software at some level – hire software
developers
• Engineers are required to convey requirements/ applications/
demands to the programming lead in the most feasible way
• Companies also use C, C++, C# and Python for their custom made
softwares

11. 3. Aesthetics – Programming is beautiful
• Programming is the art of simplifying a problem in a (mostly)
sequential way
• Common belief, that it sharpens the ability to troubleshot and solve
problems.
• It is , indeed an under-rated hobby

12. How should someone with no
experience start it?

13. Logic
Code
World

14. Quantify the Problem
Understand the Requirements
Design the Architechture

17. STEP 1:
Choose your favourite editor
EDITOR IDE
Notepad++ CodeBlocks
Emacs Eclipse
Vim Visual Studio

18. STEP 2:
Roam Around, Explore the Language
• Start with “Hello World”
• Learn If, While and Functions
• Read articles, wiki
• Download the Compiler yourself and learn
how to run programs

19. STEP 3:
Think
• Programming is like speaking
• Translate what you want to do to a
language the computer understands
• Just like “Ram Sita Love” is a grammatically
wrong sentence
• “num int = 1o“ is grammatically wrong
sentence in C language

20. STEP 4:
Design
• Draw whatever comes on your mind on
paper
• Feel free to make rough designs
• Repeat.

21. STEP 5:
Code
• Once you are familiar with the grammar,
use it to speak what you wish to do

22. The Road ahead : Choosing a path
• Web Development
• Systems Programming
• Networking
• Scientific Computing
