C/C++ source code visualization? [closed]

Answer 1

Doxygen is really excellent for this, although you will need to install GraphViz to get the the graphs to draw.

Once you've got everything installed, it's really rather simple to draw the graphs. Make sure you set EXTRACT_ALL and CALL_GRAPH to true and you should be good to go.

The full documentation on this function for doxygen is here.

Answer 2

There is an old tool called CDOC that we still use to generate call trees.
