C may be a subset of C++. However, people learning C++ as a new
language do themselves a favor by NOT learning about
storing strings in char
strcmp, strcpy, index, rindex
much of the C use of pointers
much use of macros (like those for max/min and numeric constants)
because C++ provides strings, the STL, etc. So, your assumption that a
C++ programmer can either (a) write code in the C subset of C++ or (b)
trivially strip his code down to a C core is simply not true.
