Grade 6 - ICT - Revision 05 - Algorithm and Flow Charts

How to Solve Problems?

*   Analyze the problem

*  Get a Good understanding about the problem

*  Process the problem solving in Input, Process and Output

Process of Problem Solving

1.       Input                -              Input the problem

2.       Process             -              Process them step by step

3.       Output              -              After process you get solution for the problem

Problem  01 – How to make a Milk Tea

Input                     -              Get Boil Water, Sugar, Milk, Tea leaves, tea spot, Cup, Spoon and Strainer

Process                                -   1.  Put the tea leaves in the filter

                                      2.  Pouring boiled water to the teapot through the filter

                                      3.  Adding some sugar and milk to the teapot

                                      4.  Stirring it well with a spoon

                                      5.  Pouring milk tea into the cup

Output                 -              Cup of milk tea

Problem  02 – How to Add two numbers

Input                   -              Input 1^st Number, Input 2^nd Number

Process                -              Total = 1^st Number + 2^nd Number

Output                 -              Total

What is an Algorithm?

A methods to follow a step to solved a problem is called Algorithm

How to Write an Algorithm?              

ü  An algorithm must need to have start and Stop

ü  Writing the step by step in simple English
