// This is the C++ version of the C example
//
//    ../CExamples/OO_pgm_in_C/
//
// One would not normally write a stack in C++
// this way, but use the STL stack adaptor.
//
// The C++ version is distinguished from
// the C version in that the main program is
// not generic.  For that purpose, one could have a
// function
//
//    stack* make_stack();
//
// in array_stack.cpp that is loaded at link time.
// Vice-versa, the C version could store a pointer
// to the new_stack() in struct stack, so that
// both list_stacks and array_stacks can be used
// in main.
