A simple user program for the polynomial class. To compile it, you might say something like

c++ -c poly.cpp c++ -c polymain.cpp c++ -o polymain polymain.o poly.o
This compiles each .cpp file separately, then combines them. Many build systems will take care of these individual steps when the files are assigned to the same project.
