I am trying to find the occurrences of single inheritance (SI) in C++ code and header files. Not knowing C++ all that well, I thought finding SIs would be looking for a string that meets the following criteria-

 class <str1> : public <str3>::<str2>

However I was informed by someone who knows C++ and perl (no longer here) that the best search on a given file for SI would be 

@si = grep /(class|struct)\s+[^:{;]+:[\w<>\s]+{/, $string;

I am a little shaky how this regexp works, and while it finds most of the SIs I have given it, it does not work all of the time. So I think I am a little confused on both. Any suggestions on how to robustly find SIs occurrences? Thanks --cg
