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
    malloc, free
    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.

I.e., be patient.
