C++ help finish my code
Phase 1 - input phase. Main reads the file and populates one Grocery element in the array for
each input
record. This is a standard .txt file and is delimited by new line (n) characters at the end of every
input record.
This allows you to use getline. See the Canvas assignment and copy the file named a4data.txt to
your
machine. Do not change the name of the file it must be a4data.txt. Assume that the input will be
correct.
The input record format is:
6 characters - item UPC
20 characters - item description
6 characters - cost (999.99 format)
6 characters - selling price (999.99 format)
3 characters - inventory on hand
1 character - status (o on order; d discontinued; s on shelf)
Use correct read loop logic as discussed in class.
There is no constructor. The Grocery array is statically allocated, so if there was a constructor, it
would be
executed when the array was first defined, once per element.
The maximum number of grocery items is 100, and youll need a counter to keep track of how
many there
actually are. Define that counter as a static variable in the Grocery class, and use it throughout
your code as
needed.
At the end of phase 1, main has built a set of Grocery objects.
Next, main should display all the Grocery objects to ensure that the array has been built
correctly. Examine
the input data and determine if your code is processing all the records, and each record correctly.
Display
them after you have processed the input file; do not list each object as its created within the read
loop. Use
some appropriate column formatting so that you can make sense of the output, and so that you
can verify

that the objects have all been created and populated correctly. At this point, there is no price
history data,
that will be added in the next phase. Your display should look something like this:
=====================================================================
=
UPC Description Cost Price Inventory Status
=====================================================================
=
123456 Peas, canned, 12 oz 1.23 1.89 100 s
234567 Tomatoes, sundried 2.25 3.75 25 s
345676 Pineapple, whole 2.99 4.25 0 o
Phase 2 Transaction processing phase. Main asks the console user for transactions. Use getline;
do
not use some other form of input. There are four different types of transactions. Assume the
transaction data
is valid (no error checking needed). There are four types of transactions:
D
Display a list of all Grocery items, one item at a time, something like this:
=====================================================================
=
UPC Description Cost Price Inventory Status
=====================================================================
=
123456 Peas, canned, 12 oz 1.23 1.89 100 s
Price history: 2021-03-17 1.11
2021-04-17 1.45
2022-06-14 1.89
234567 Tomatoes, sundried 2.25 3.75 25 s
Price history: 2021-03-17 1.98
2021-04-17 2.25
345676 Pineapple, whole 2.99 4.25 0 o
Price history: there is no price history for this item
. . .
H upc date price
Add a price history to the grocery item with UPC code upc. The upc, date, and price fields are
fixed in size and

separated by blanks. Perform a linear search for the item. If its found, add the history and
display a success
message. If the UPC isnt found, display a not found message. You may assume that you will
never add
more than 25 history items per grocery item.
C upc1 upc2
Compares the number of price history elements for the two items specified by upc1 and upc2. If
the number
of elements is equal, display a message saying they are equal. Otherwise, display a message
saying they are
not equal. Use an operator== overload to implement the comparison. If either upc is not found,
display an
error message.
X
Clean up and exit.
