Overview

In this tutorial, we will learn about IBM FLowchart Symbols. The flowchart symbols are from the Flowgorithm flowchart tool.

IBM Flowchart Symbols

The basic flowchart symbols are as follows:

 

IBM Flowchart Symbol	Name	Description
	Input	The Input statement reads the value from the standard device like the keyboard and stores the value in a variable.
	Output	The Output statement displays the expression result to the computer screen.
	Declare	The Declare variable is used to create variables in the flowchart. The Declare statement specifies the data type of the variable.
	Assign	The Assign statement is used to store program data into the variables.
	If	The If statement evaluates a boolean expression and then executes either the True branch or the False branch based on the value of the boolean conditional expression.
Loops
	While Loop	A While loop evaluates the boolean condition and if it’s True executes the loop statements. The block loops until the expression is False.
	For Loop	A For loop statement executes the loop statements for a specified number of iterations. The loop variable increments or decrements through a range of values.
	Do While Loop	A Do While loop is similar to the While loop, but the statement executes the loop statements at least once. This is a post-test loop i.e it tests the condition after executing the loop statements. It evaluates the boolean condition and if it’s True executes the loop statements. The block loops until the expression is False.
File I/O
	File Open	The File Open statement opens the file for the read/write operations in the flowchart.
	File Read	The file Read statement reads the file contents and stores the data into a variable.
	File Write	The file Write statement writes the data to the file.
	File Close	The file Close statement closes the file handle in the flowchart.
