How to Draw Flowcharts for Programs

 

Flowcharts is a graphical representation of an algorithm. it makes use of the basic operations in programming. All symbols are connected among themselves to indicate the flow of information and processing.

A Flowcharts is a diagrammatic representation of the various steps involved in the solution of a problem.

Flowcharts is a symbolic diagram of operation sequence,data flow,control flow and processing logic in information processing.The symbols used are simple and easy to learn.

Symbols used with flowcharts

Name	Symbol	Purpose
Terminal		Beginning/End of the flowchart
Input/Output		Input/Output data
Process		Mathematical calculations, data transfer and logic operations
Decision Making		Alternate paths
Connector		Transfer to another point in the flowchart
Circle		Need to connect to another page or another section of the chart
Display		Show the information is being displayed to the user

 

Example on Flow Charts for Programs

           We are using num1 , num2 and sum as variables for our program . So first of all we have to draw  a Program start box  and similarly for stop also .

 Next we should describe the variables that are declared in program like….num1 ,num2 here.

 Now To read values we need to use titled rectangle(parallelogram) as shown in diagram .

 Next All the login must be show in Rectangle as shown in diagram.

For all read and display operations you have to use titled rectangle(parallelogram) as described earlier.
