AgendaWhat 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)

Programmer, Program, Machine& Executor

Executor

Program

Slow execution

Inputs

Little history Abacus

History I would say a wheel also has a program which is kind of hard coded

Input - pressureOutput - Rotation

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

Machines around usBit – On / Off

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

The language of circuits – 2 way switches

S1 S2S1 S2 Output

0 1 0

1 0 0

1 1 1

0 0 1

CPU – Universal circuitGive me any

circuit diagram. I can act like

that

When I don’t know programming?

I need water

पा�नी� ला�नी�

TranslatorWorkers

It fails sometime

For drinking

पा�नी� के� लिलाए पा�नी� ला�नी�

Better ask him write down and

fire him

Why should I learn programming

पा�नी� के� लिलाए पा�नी� ला�नी�.Hot..Hot..

Oh…God Forgot to ask him how to ask hot water

Objects in programmingProgram

Machine / Executor

Input

Output

Karel – A simple robotA Programming language used for educational purpose

Supported operationsMove()TurnLeft()

Simulatorhttp://joymononline.in/apps/karel/karel.htm

Making more tasks using KarelDynamic decision making using IF keyword

Repeat same job using LOOPING

Keep the instructions of one job in group called FUNCTION

TheoryTuring machine & Universal Turing machine.
