I do think the TokenStream+snippet approach would suffice for C++
as well as C. If you look at all the stuff I'm doing for C to Java:

...I don't think C++ would be an insurmountable next step.

Having said that, I do feel obligated to point out that
my approach really "doesn't suffice" even for C to Java.
There's no way that I can translate any arbitrary pointer
usage, for example. The best I can do is look for the common
patterns of usage of pointers, and translate to the Java
equivalent. But if someone uses memset() to set memory
location 12345 to value 12345, there is no Java equivalent.
(Or even the standard swap(&a, &b) method, for example).
