vendingMachine | This is a full-stack app of a vending machine | Continuous Deployment library

I have a segment of code here that runs partially. I am able to input both the characters (c, a, r) and numbers initially, but after entering a character input, the code no long accepts integer inputs. Why does this happen?

I think it has something to do with my try catch exception.

code:

I am trying to use stroi in my "vending machine" code below. I had a working vending machine before I tried to add a feature that allows users to enter characters ("c" for checkout, "a" for add, and "r" for remove) as well. Since my user input can be both int and char I realized I had to convert strings to numbers. I have checked references but none give an example of how to use it with vectors. Can someone please help?

Currently, there is an error located at the int myint1 = stoi(item); line in the if statement in the main. It says "use of undeclared identifier 'i'."

Note: I am fixing my code so it does not run. But when it did, the code breaks after 2 user inputs and I am not sure why.

Here is an example of what I am trying to code:

Vending machine:

----Items----

(5 listed below)

what item would you like to buy? Enter "c" to checkout, "a" for add item and "r" for remove item.

-If user input is an integer, then run the enterSelection function

-If user input is a character (c, a, or r) , then:

if "c" , then run checkout function

if "a", What Item would you like to add and for what price? Then append to menuItems and cost accordingly.

if "r", what item would you like to remove (enter a number)? Then erase the item from menuItems.

Then print: "User input" has been added/removed from the menu.

When the menu is displayed again, the user edit will show.

And yes, I know there are many more problems with my code that I do not know how to fix.

Full Code:

I am working on the "checkout" process of my vending machine code. I want to write it so that the program will keep asking for the amount needed from the user until all the money is entered. However, this code segment does not completely work.

"Checkout" Segment of Code:

I am progressing on my "vending machine" code where users are able to add an unlimited amount of items to the cart until they press 0 to checkout. I ran into a problem with the array cost[item] in my "do-while" loop where it says "subscripted value is not an array, pointer, or vector." Could someone please help me with this? I also have a few smaller problems if someone would like to help. Here are my main problems I ran into:

1. the press 0 to checkout part of the code - I think this problem is related to the cost[item] array problem I described above.

2. how to get my menu prices to display 2 digit decimals - I am not sure where to put cout << fixed << setprecision(2) << total; in my code if that is the correct way of doing it.

3. how to print a statement when "checking out" to display items with total cost.

my full code:

I am writing some code and ran into an error when I need to return multiple values to main() from another function.

Here, I am trying to return item and total to the main() function. However, I am getting a warning saying that item has not been used, but I am using it in main(), where it then says "use of undeclared identifier" along with total.

Could someone help me with my syntax issue here?

I have a test class created. I need to run the test file using spring dependency injection . I am using the XML method.

How to define a bean for Inventory in your XML configuration?

Testfile constructor:

Working in Spring, and using H2 for now.

So, I have these two classes/Entities with their repositories working fine if I keep it simple.

Brand, which simply has a name and a price;

and VendingMachine, which has a model and some other properties;

BUT I need to implement this:

Different VendingMachines sell different Brands, for which they have a stock. The Brands it sells are determined when you instantiate the class.

So my idea is that the table for VendingMachines fields should look something like that:

MODEL////ID/////MAXCAPACITY////MAXBRANDS///BRAND01////BRAND02///BRAND03...

Where all the BRAND columns are the different Brands the machine sells, assigned at its instantiation as said before. The value will be an Integer.

My original idea was to send this data to the @Entity via a HashMap(Brand, Integer) but I don't know how to make it work once it tries to fit it into the JpaRepository, or even if it is possible this way.

Probably missing some magic Annotation I don't know.

Thanks, hope my question was well explained for everyone.

this project i use do while loop with switch case to check the input case is not match or not. i run the code but the result not what i wanted. what i expect is if the user type the wrong case, the do while loop will loop back to the input where user need to enter the case.

here is the code
