I feel like if you're going to say that C and C++ are very different, there are some stronger motivating examples. Casting rules on void pointers is a tiny thing compared to general stylistic differences. C code filled with macros being replaced by C++ classes and template instantiations makes code just on an aesthetic level look very different. RAII vs "getNewX/destroyX". Not judging either flavor, but I think it's rare to see a file of "C/++" code and not immediately grok what you're looking at.
