How Can I Track the Total Sales in My Mini Store Program?

It sounds like you need to store the grand total for all products sold during the session. You can do this by declaring a variable outside the loop that keeps a running total. Every time you calculate a grand total for an item, just add that to your main total. Here’s a quick idea: Before your while loop, initialize a variable like `double overallTotal = 0;`. Then, after calculating each product's grand total, add it to `overallTotal` like `overallTotal += grand_total;`. Finally, once the user decides to stop entering products, print out `overallTotal`. That way, you'll have a combined total of all sales! Good luck!

To clarify, you're looking for a single grand total of everything sold, right? Right now, you're getting the total for each item, which is great. What you want to do is take each item's total (after tax) and add it to a running total. Like the previous commenter said, declare a variable for the overall total before the loop, and add to that variable as you calculate each product's grand total. At the end, when you quit the program, just print that overall total. It might also help to keep an array or a list if you want to store the details of each product, but that’s optional for just tracking totals.
