Could someone shed some light on how to find the code snippets related to the implementation of the "new" operator?

Thank you for taking the time to respond to my question.
I see. I have found it with your generous help.

One more question, why the implementation is in the folder named
libsupc++ other
than src(i.e.  libstdc++-v3/src/)? And what does libsupc++ stand for?

Thank you.
Best Regards.
