Algorithm Notes Class 8 Computer Science

Developing algorithm to solve particular problem
 
In mathematics and computer science, an algorithm is a step-by-step procedure for calculations. Algorithms are used for calculation, data processing, and automated reasoning.Algorithms resemble recipes. Recipes tell you how to accomplish a task by performing a number of steps.
For example, to bake a cake the steps are: preheat the
oven; mix flour, sugar, and eggs thoroughly; pour into a baking pan; and so forth.
 
Goals of Algorithm Study
 
• To develop framework for instructing computer to perform tasks
 
• To introduce notion of algorithm as means of specifying how to solve a problem
 
• To introduce and appreciate approaches for defining and solving very complex tasks in terms of simpler tasks;
 
Simple Questions based on Algorithm
 
Algorithm: Calling a friend on the telephone

Input: The telephone number of your friend.

Output: None
 
Steps:

1. Pick up the phone and listen for a dial tone
 
2. Press each digit of the phone number on the phone
 
3. If busy, hang up phone, wait 5 minutes, jump to step 2
 
4. If no one answers, leave a message then hang up
 
5. If no answering machine, hang up and wait 2 hours, then jump to step 2
 
6. Talk to friend
 
7. Hang up phone

Step 5: Put magi and masala

Step 6: Give two minutes to boil

Step 7: Take off the pan

Step 8: Take out the magi with the help of fork/spoon

Step 9: Put the Maggi on the plate and serve it

Step 10: Stop.
 
Algorithm: To find (a + b)2=(a + b)* (a + b)

Input: Two numbers a and b.

Output: Result of (a + b)2
 
Steps:

1. Take numbers a, b, c.
 
2. Input the values of a and b

3. C=a+b

4. Print c*c

Algorithm: To find Perimeter of rectangle

Input: Two numbers l and b.

Output: Result l*b

Steps:

  1. Take numbers l, b, c, d.
  1. Input the values of l and b
  1. c=l*b
  1. d=2*c
  1. Print d

Conditions in Algorithm

Algorithm: To check whether a person can vote or not

Input: A number age.

Output: Yes or No

Steps:

1. Take a number age.

2. Input the age of the person

3. If(age>=18) goto step 4

           Else

        Goto step 5

4. Print “You can vote”

5. Print “You can’t vote”

Algorithm: To give a bonus of Rs 1000 to those employees whose salary is more than Rs5000

Input: Salary.

Output: New Salary

Steps:

1. Take numbers salary and total.

2. Input the salary of the person

3. If(salary>=5000) goto step 4

              Else

          Goto step 5

4. total=salary+1000

5. total=salary+0

6. Print total
