C++ ``Dynamic Stack'' class

This is a similar version of the previous dynamic-stack example, but using a C++ class, rather than a structure.

Compile with g++, using the command:
g++ -o tdstack tdstack.cc dstack.cc

or CC, using the command:
CC -o tdstack tdstack.cc dstack.cc

to create the executable ``tdstack''.

Source and header files:

tdstack.cc (tester program)
dstack.h (header file for DStack declarations)
dstack.cc (source code for DStack functions)
