I need assistance with figuring this out.

What is the code supposed to do?
josephhoffman28 (53)
*Use 2 arrays: one for the products, and one for the quantities.
*Use loops to assign values to the arrays.
*Use loops to read and print values from the arrays.
*Complete the following in your code:
*Provide a list of available products
*Ask the customer to select products and quantities
*Save the provided details in arrays
*Read from the arrays to print the order summary; that is, the products, quantities, and the total price for each product
*Calculate and print the total price for the order

These are the requirements.

Remaining issues.


assignment detail:

Complete the following in your code:

*Provide a list of available products

*Ask the customer to select products and quantities

*Save the provided details in arrays

*Read from the arrays to print the order summary; that is, the products, quantities, and the total price for each product

*Calculate and print the total price for the order

I am getting errors on the following:

line 75 "expected a ')'

line 76 "expected an expression"

line 85 "identifier "beverage" is undefined"

line 85 "identifier "quantities" is undefined"


Along with this what should go into the function
doneShowOrder
:

1
2

5
 
void doneShowOrder(const Customer &, Quantities)//NEED HELP FIGURING OUT WHAT DO DO

{

}


These seem to be the only remaining issues I have.
