GUIDELINES FOR MAKING FLOWCHARTS
 ACTIVITY-2      When creating flowcharts, it’s important to follow certain rules to ensure clarity and effectiveness.
                 Some rules for making flowcharts are:

 (c)  Add

 (d)  Insert

 (e)  Add           two outgoing lines.

  (f)  Save          Inside each symbol, write a brief action or question that clearly describes the step.
                     Use uniform shapes and equal spacing to make the chart easy to read.
                     Do not leave an arrow without a destination symbol.


 FLOWCHART       SOLVING PROBLEMS USING FLOWCHARTS
                 Example: Design a flowchart for the online decision of whether to click on a suspicious link.
 A flowchart is a diagram that uses shapes and arrows to show steps in an algorithm. It displays   The flowchart for the online decision to click on the suspicious link:
 the steps in order and helps us understand and check instructions quickly. Flowcharts are used in   Start
 many fields to analyse, design and manage processes.

 SYMBOLS USED IN FLOWCHARTS            Receive a suspicious link

 Different symbols are used to draw different types of flowcharts, as shown in the following table:

 Symbol  Name  Description                  Link from a       No      Do not click on the link
