Question

Is there any free C/C++ code to flowchart generator tool available on the net for download?

Answer 1

Doxygen doesn't make flowchart persay, but it can generate do a function graph for you. The following answer is for php, but Doxygen works for C and C++ as well.

Answer 2

SCItools makes a product called Understand that provides a number of metrics as well as flow charting of execution. There is a free trial available, but the licensed version is pretty spendy. I don't think there are any limitations on the demo, but I'm not sure.

Answer 3

GraphViz can generate all kinds of pretty graphs/charts. Doxygen uses a tool built on graphviz, called Dot, to generate its function call flowcharts.

You can either call graphviz as a library (it's written in C), or generate the Dot language and then execute the dot program on it.

Answer 4

Source Navigator NG is a pretty good, free ( and open source) alternative to the big guys like Understand for what you want.

Answer 5

I work on a tool called Code Rocket that can generate flowcharts from C/C++ code (and C# and Java) and vice versa that you may wish to try. Its not a free tool but there is a fully functioning 30-day free trial available on our website.
