Visustin - Sample flow charts

This page presents sample flow charts created by Visustin, the flow chart generator software.

Algorithm flow charts

Below you can find short algorithms flowcharted. You get to see the same code as a flow chart, UML style activity diagram, Visio diagram and a PDF version. See how much easier it is to understand the code by watching the flow chart rather than by reading the source alone.

Algorithm	Flow chart	UML	Visio	PDF	Description	Language
DaysInMonth	Flow chart	UML	Visio	PDF	Get number of days in a month	VB.NET
IsValidDate	Flow chart	UML	Visio	PDF	Determine if date is valid	VB.NET
RomanNumber	Flow chart	UML	Visio	PDF	Convert integer to roman number	VB.NET
Selection sort	Flow chart	UML	Visio	PDF	Sort a number array	C
Quicksort	Flow chart	UML	Visio	PDF	Sort a number array (recursive)	C
Quicksort, iterative	Flow chart	UML	Visio	PDF	Sort a number array (not recursive)	C (pseudocode)

PDF note: Visustin does not have built-in PDF functionality. The PDF files have been created by printing on a free 3rd-party PDF printer driver. Tip: Try printing a PDF file to see how Visustin charts look with your printer.

PicInfo sample flow charts

This example was created from the code of a little Visual Basic program called PicInfo.

Code module	Flow chart	Activity Diagram	Visio diagram	PDF
PicBMP class	Flow chart	UML	Visio diagram	PDF
PicGIF class	Flow chart	UML	Visio diagram	PDF
PicForm form	Flow chart	UML	Visio diagram	PDF
PicMain module	Flow chart	UML	Visio diagram	PDF

All modules: PicInfo.code.gif and PicInfo.code.tif. These are multi-image files. Save them to disk and open in Visustin.

PicInfo is a sample program that reads BMP and GIF files and displays image information such as image size. To get the entire PicInfo source code, download Project Analyzer and check out its Sample folder. There you can also find a full code analysis of the same code.
