Updated Code

Good Morning World! As I start yet another semester learning to make new, better codes, I'd like to post an update to one of my codes I previously posted for calculating the estimate cost of items purchased after applying Sales Taxes in the Province of Quebec, Canada.

Previously, the effective sales tax in Quebec was 7.875% (QST) and the sales tax across Canada is 5% (GST), making a total tax rate of 12.875% for Sales Taxes combined in Quebec (QST+GST) for the year 2010.

Currently, the effective sales tax in Quebec is 8.925% (QST) and the sales tax across Canada is 5% (GST), making a total tax rate of 13.925% for Sales Taxes combined in Quebec (QST+GST) for the year 2011.

The following code can be used as a dummy program imitating a cash register at any general store (Grocery, Fast Food, Restaurant, etc.).

Stay tuned...
