Flowchart is a diagrammatic representation of an algorithm. Flowchart are very helpful in writing program and explaining program to others.
Symbols Used In Flowchart
Different symbols are used for different states in flowchart, For example: Input/Output and decision making has different symbols. The table below describes all the symbols that are used in making flowchart
|Flow line||Used to indicate the flow of logic by connecting symbols.|
|Terminal(Stop/Start)||Used to represent start and end of flowchart.|
|Input/Output||Used for input and output operation.|
|Processing||Used for airthmetic operations and data-manipulations.|
|Desicion||Used to represent the operation in which there are two alternatives, true and false.|
|On-page Connector||Used to join different flowline|
|Off-page Connector||Used to connect flowchart portion on different page.|
|Predefined Process/Function||Used to represent a group of statements performing one processing task.|
Examples of flowcharts in programming
Draw a flowchart to add two numbers entered by user.
Draw flowchart to find the largest among three different numbers entered by user.
Draw a flowchart to find all the roots of a quadratic equation ax2+bx+c=0
Draw a flowchart to find the Fibonacci series till term≤1000.
Though, flowchart are useful in efficient coding, debugging and analysis of a program, drawing flowchart in very complicated in case of complex programs and often ignored.
