Tool to visualise code flow (C/C++) [closed]

Answer 1

KScope, built upon the cscope utility, if you're on linux (KDE). The best thing I ever used (and use all the time) to deleve into some huge piece of unfamiliar code which I have to modify somehow or which API I'm to employ for my needs. Among its features are the cross-reference database, which can be searched in a plenty of ways: you can find all references of a symbol, its global definition, find callers/callees of a function and much more. It even has a built-in IDE and an ability to show a call-graph.

Answer 2

I personnaly use Visual Studio debugger tools.

It comes with the "Caller Graph" feature which will allow you to visualize stuff in little boxes. Also the Call Stack and the usual watch features are usually all I need

Answer 3

I used Borland Together a while back and it did a decent job of generating models from code. I believe it will even generate sequence diagrams from code. Keep in mind if your code is a mess your model will be too. And as I recall it isn't cheap but sometimes you can catch a special.

Answer 4

try AQtime, It's a profiling tool that displays all the functions that got called (and the time it took), you can set the start and end points for the analysis. They have a 30 day trial.

Answer 5

doxygen is a free doc-generating tool (similar to Javadoc) that will also produce relationship graphs as well.

Answer 6

Profiling software gives you an idea of which functions have been called.

If you can use Linux, try KCachegrind
