Fundamentals of computer programming:
Let's get started:
Time to get our hands dirty!
Let's go into the world of programming!
Let's get started:
Time to get our hands dirty!
Let's go into the world of programming!
Computers are pretty dumb, literally have no brains!!
Then how do work computers?
So,say thanks to programming! that's how we make computer do cool
Cool stuff for us.
So don't angry on computer, don't do stupid to things on computer!
Computers are doing capable of complex calculations.
Computers think " your wish is my command".
Programmer thinks " Do I press enter after the your wish".
What if we get computers to slove problems for us?
Well,we are learn about to learn just that
Programming let us slove problems by giving instructions to computers!
Programming is a problem solving
Steps involved in problem solving:
Programs:
programming is everywhere
Beware! programs are everywhere, it's on integral part
Of our life now
This website using you are right now is a program,and
And so your alarm clock and digital watch
We spend 80% of our time is interacting with different
Programs
For example mobile apps, laptops/desktop applications,
Operating systems,web browsers.......................and so on.
Every thought that all the tasks we do based on the
Sequence of steps?
Ex: feeling hungry?our steps.
1. Open the fridge.
2. Get food out.
3.close the fridge.
4. Eat the food.
We use similar sequences of logical steps in
Programming
For example tasks required you to follow a sequence
Of steps are write a compute program,cooking,......etc
Computers work useing programs
Programs are sequence of instructions.
Programming is sloving the problems with steps of
Instructions
Storage:
Humans forget something! But computers don't forget!
Let's put that memory to good use by learning how to
Store information in the computers
Remeber what you had for yesterday lunch? No
Don't worry , computers never forget anything if they
are told to remember
We are about to learn how to use this superpower of
Infinite memory
Variables:
To remember things ,computers use memory boxes
are called variables.
They can change their values.
Like boxes , variables have a label and store content
in them.
Numbers+computers is a great combo to carry out
arthmatic tasks.
Even if we are mathematicians,it would be hard to
beat the speed and accuracy of computers.
Unlike numbers ,words (also called strings)
This is where we use boxes with space to store
multiple values also called lists.
Notice that? Lists are suitable to store multiple
values , particularly when they are of the same type
Repeating things:
For example wish I could blow all the balloons once
How many times have you repeatedly done a task?
Just one or two times we well get tied,not too many
many times, it's wanna get bored
But computer never get tied and can repeat stuff
over and over again and never get bored.
Loops:
The repetition of steps is known as loops.
As a computer programmer,you should be able to
identify repetitive tasks and wrap them up in loops
If you don't know how many times a sequence to be
repeated?
Don't worry, in such a situation we use the untill
Condition loop or while_ condition loop.
The untill loop or while _loop is condition_controlled
loops which repeat till the conditions reached
Repetitive tasks handeld better by using loops.
Loops can have fixed number of repetitions.
Loops can have conditional number of repetitions
(Untill condition is met).
Making decisions:
Computers can make decisions for us?
Remember we learner computers can't think?
So we have also tell the computer what decision to
make!
Computers have to be told to take decisions based on
Conditions
Using if ....then...else:
Computers use simple words such as if and then to
guide their actions.
Conditions the computers decided what action to
Perform and when
conditions make the programs more intelligent
Else if
Computers can't decide themselves
We help the computers decided by creating conditions
based on situations
These conditions make the programs seem intelligent
Programs with conditions help the computer perform
the action in right situations
Creating lists:
Lists are used to store set of related values.
Items of lists can be sorted rearranged, replaced
and removed
You can perform the tasks on each item of list together
Once
Grouping instructions:
We do daily a few similar activities such as eating,
bathing, brushing, break fast and more.
These activities follow similar set of sequences and
are repeatedly follow in similar ways
Unfortunately real life doesn't allow us a short cut,but
hey computer world is does!
We are about to find out how........
Well,programs as well contain parts that are repeated
many times.
Computers think " your wish is my command".
Programmer thinks " Do I press enter after the your wish".
What if we get computers to slove problems for us?
Well,we are learn about to learn just that
Programming let us slove problems by giving instructions to computers!
Programming is a problem solving
Steps involved in problem solving:
- Define a problem
- Break the problem into smaller parts and analyze
- Plan the steps for solution
- Implement the solution
