ctags can generate a cross reference file which lists, in human readable form,
information about the various source objects found in a set of language files.

Many editors will read tag files and provide easy lookups for you.  There are
many C/C++ to HTML tools as well, which will hyperlink between the function
calls and the method for you.  I recall using them in the mid-1990s.

If you are using C++, then you really want to use a class diagrammer.  Almost
any of them will reverse from source code.

I'd provide exact tools, but I haven't written any C++ in over a decade.
