Crystal FLOW for C

This is a software tool that will let you create flowcharts from source code in C.

Being able to read code and understand the underlying logic is very helpful in the software life-cycle phases of software applications and products. Creating flowcharts of the source is a valuable tool in this regard. This is a software tool that`ll help creating flowcharts out of the source code automatically. Some scenarios where flowcharting the code would be useful include when an application need to be maintained on an on-going basis, when you need to do code review of an on-going project or a new member joins a development team or even the IT team. The flowcharts can be created in different forms. These are level, optimal, loop and conditions. If you were to discuss the flowcharts with people outside the development or the maintenance team, you are able to add annotations to the flow charts to illustrate the points you want to make.

If, as a developer, you wanted to look at different areas of code, this tool provides many a views that can help. DataFlow with Rich Trees, Object DataFlows, CallFlows, Flowchart inline expansion, Add-On - document generation are some of the possibilities. Code only, comment only, code + comment trees of calls and items called, object/stack size, data dependency and so on are several ways to look at code and understand it. When browsing you can synchronize the flowcharts and the code so that you can view them side by side in the viewing window. Flowcharts can be exported as Image/vector diagrams in BMP, JPEG and Visio formats. That eases documentation work. The program will let you print large flowcharts that can be useful in documentation. A very useful tool for all C developers!
