The NumberDuck.hpp and NumberDuck.cpp files can be dropped directly into your existing build setup.
The examples in the zip can also be built and ran from the command line, here's the simple example:
g++ -o SimpleExample SimpleExample.cpp ../NumberDuck.cpp ./SimpleExample
The NumberDuck.cs file can be dropped directly into your Visual Studip project. You will also need to reference the System.IO.Compression assembly.
The examples in the zip can also be built and ran from the command line, here's the simple example using mono:
csc -debug:full -reference:System.IO.Compression.dll SimpleExample.cs ../NumberDuck.cs mono --debug SimpleExample.exe
