Project $5$ Online Groceries PART $1$

Background You are building a system to allow customers to order groceries. You have two files with data:

$$ customers.txt

$$ items.txt

The first file holds customer data in a single text line the following:

$810003,$Kai Antonikov,$31$ Prairie Rose Street,Philadelphia,PA$,19196,215-975-7421,$kantonikov$0$@$4$shared.com

The data fields are the customer id$,$ name, street, city, state, zip, phone, and email. The file items.txt has fields item$\_$id$,$ description, and price:

$57464,$Almonds Ground Blanched,$2\mathrm{.}99$

Requirements

Write a program that does the following:

$1.$ Read $$customers$.$txt$.$ Put the customer records into a $($global$)$ vector.

$2.$ Read $$items$.$txt$.$ Put the item records into a vector.

$3.$ Display a message stating how many customers there are, and how many items there are.

$4.$ Prompt the user for a customer number. Search for the customer record.

a$.$ If the customer is not found, exit the program with an appropriate message.

$2.$ Read $$items$.$txt$.$ Put the item records into a vector.

$3.$ Display a message stating how many customers there are, and how many items there are.

$4.$ Prompt the user for a customer number. Search for the customer record.

a$.$ If the customer is not found, exit the program with an appropriate message.

b$.($You may assume that the user always enters a number.$)$

$5.$ Prompt for the item number to purchase.

a$.$ Display the item description and price.

b$.$ Keep track a running totals of items bought, and amount spent.

c$.$ If the item is not found, display an appropriate message and continue.

d$.($You may assume that the user always enters a number.$)$

$6.$ Continue asking for items until the user enters a $0$ for the item number.

$7.$ Display a message with the number of items purchases and the total cost.

a$.$ The total cost should be displayed as a typical money number with a $ sign and dollars and cents. For example, if the total is $$2\mathrm{.}00,$ display it as $$2\mathrm{.}00.$ Not $$2.$ This means you will have to use a bit of output stream formatting.

$8.($The program calculates only one customer$$s order. Do not repeat the steps $4-7.)$ Put all your code in a file called groceries.cpp$.$ Use this main function:

int main$()$

$\{$ read$\_$customers$("$customers$.$txt$")$;

read$\_$items$("$items$.$txt$")$;

one$\_$customer$\_$order$()$;

$\}$

The rest of the steps NOTE:

You will have to declare classes and customers and items. Because they are simple data structures, and you WANT all the data to be available, you can just use a struct for each $($which is the same as a class with all public members.$)$

Design considerations:

$1.$ What goes into the Customer class $($or struct$)?$

You can see a customer record has: a$.$ Customer id $($which is an integer$)$ b$.$ Name c$.$ Street address d$.$ City e$.$ State f$.$ Zip code: even though it is a number, store it as a string. g$.$ Phone number: also a string $--$ just keep the dashes h$.$ Email address

$2.$ What goes into an Item?

a$.$ Item Id $($an integer$)$ b$.$ Description c$.$ Price: This has to be a number, and not an integer! Store it as a double.

$3.$ How do you read in a record and create an object from it$?$ See note below on a function called split$()$ that we will provide for you.

Implementation Notes

I have provided a file, split.h$,$ which contains a split function that returns all fields that were separated by some character as a vector of strings. You can also use this function to separate the item$\_$id$-$quantity pairs using a dash as the split character.
