Visustin - Sample flow charts
This page presents sample flow charts created by Visustin, the flow chart generator software. All diagrams were created programmatically with no human adjustment.
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.
Tip: Try printing a PDF file to see how Visustin charts look on your printer.
Greatest Common Denominator flow charts
This example flowcharts the well-known Greatest Common Denominator (GCD) algorithm in various programming languages.
If you're interested, compare GCD in C to the Binary GCD algorithm earlier on this page. The algorithms perform the same task, but look different. The binary algorithm seems more complex, don't you think? There are more loops in the binary algorithm as it plays with the simple bit shift operators (>>). That's the where the "binary" comes in its name. The "regular" GCD algorithm manages with a single loop using the more powerful modulo operator (%).
