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
