The platform used is C++. Hence we decided to use Microsoft Visual Studio 2010/2008 edition (Professional Edition).

For optional coding and easy debugging we used Microsoft Visual Studio 2008 edition and made explicit .cpp files.

Henceforth for optimal usage of such software a windows based operating system preferably Windows vista/7/XP must be there. Also on the hardware part any system having Windows Vista/7/XP installed will suffice.
