The document provides an introduction to programming, covering fundamental concepts such as the definition of a computer, the role of a programmer, and the evolution of programming. It emphasizes the importance of learning programming through practical examples, including a simple robot language, Karel, and discusses basic programming concepts like input, output, and decision-making. Additionally, it touches on machine coding, high-level languages, and the differences between compiling and interpreting code.

life

2. Agenda
What is computer, program, input and output? Who is programmer?
Some history
Evolution of computers
Why I should learn programming
Writing first program
Basic things you know when writing programs?
Some theory (Only if time and you permits)

3. Programmer, Program, Machine&
Executor
Executor
Inputs
Program
Slow
execution

4. Little history
Abacus

5. History
I would say a wheel also has a program which is kind of hard coded
Input - pressure
Output - Rotation

6. History – programing wheels
Arranging wheels in different ways produce different programs.

7. Machines around us
Bit – On / Off

8. Circuit
Machines which accept more than one on/off conditions (1 bits) as input

9. The language of circuits – 2 way
switches

10. CPU – Universal circuit
Give me any
circuit
diagram. I can
act like that

11. When I don’t know programming?
I need
water
Workers
Translator

12. It fails sometime
Better ask
him write
down and
fire him
For
drinking

13. Why should I learn programming
.Hot..Hot..
Oh…God
Forgot to
ask him
how to
ask hot
water

14. Objects in programming
Program
Machine / Executor
Input
Output

15. Karel – A simple robot
A Programming language used for educational purpose
http://en.wikipedia.org/wiki/Karel_(programming_language)
Supported operations
Move()
TurnLeft()
Simulator
http://joymononline.in/apps/karel/karel.htm

16. Making more tasks using Karel
Dynamic decision making using IF keyword
Repeat same job using LOOPING
Keep the instructions of one job in group called FUNCTION

17. Theory
Turing machine & Universal Turing machine.
Machine code
High level language
Compiling v/s interpreting

18. Thanks for asking questions
