As for additional information about Cppcheck, here are a few notes:

* Cppcheck supports various metrics and checks, including but not limited to:

+ Lines of code

+ McCabe's complexity metric

+ Metrics proposed by Chidamber&Kemerer and Henry&Kafura

If you're looking for more information about other tools mentioned in your text, here are a few notes:
