This project teaches you how to use simple math computations
to compute sales tax and how to format the results to look like
currency.

I introduce the concept of 'casting' which simply means to convert
one data type to another.
Also shows how to use string formatting style

	Showed how to use Double::Parse instead of Convert class.
	Also how to use composite string formatting for summary

	//---now display the results and format as currency

	//---format numbers using 2 decimals with no $ sign (n2) using differenct styles:
	Console::WriteLine ("\n\nSummary of Purchase\n\n");

	//---composite formatting style
	Console::WriteLine ("You purchased: {0}. ", whichProduct);
	Console::WriteLine("The price of your item is {0}.", price.ToString ("n2"));

	//---concatenation
	Console::WriteLine ("\n\nYour total purchase is " + balanceDue.ToString ("c2"));	//with a $ sign (currency)


	//---use composite formatting feature style
