3. make tempText static in readText.  Of course, this will prevent using
readText from multiple threads.  But strtok is not thread-safe either.  So
using 'static' is ok.

I should note, using <cstring> is not very object oriented nor C++.  The
standard C++ library string class is very powerful, and has capabilities
to do the things you want.  But I don't know the purpose behind using
strtok and friends.  So I can't say if going straight OO is the correct
path.
