Answer 1

You have invalid characters in that code, which prevents the code from being compiled.

And you should replace the '–' character with a hyphen '-' in the line where you calculate the discounted amount.

* Replace this line
double amount_with_discount = amount_without_discount – (amount_without_discount * 0.1);

* With this 👇
double amount_with_discount = amount_without_discount - (amount_without_discount * 0.1);

Notice the use of hyphen on second example.

* You can also opt to do this instead.
double amount_with_discount = amount_without_discount * 0.9;

Answer 2

You can actually make your code easier to read by doing this:
double groceries, vegetables, beverage;
