The point here isn't copy pasting C code into C++ verbatim. The changes needed to translate C code into valid C++ code that does the same are very simple. One could translate many thousands of lines of C into C++ in an hour. More so, the point here isn't even translating an existing codebase where small bugs could surface. It's just explaining concepts. None of the C to C++ differences would matter. If an answer to OPs question was in C, he could trivially convert that C example into C++.
