Question
With this assignment you will start to learn how to
write a practical menu driven program that manages
a list of data. You will use an array of structs to
organize the data and you will save the informatio
n in a
text file.
The assignment is to write a menu driven program th
at manages a small business inventory, collection
or list. You pick the topic!!! The focus of your pr
ogram is up to you.
The Menu commands must include:
P....Display all records (on the screen/monitor
)
S....Create a current report (save it to a file
)
A....Add a new entry
D....Delete an item from the list (inventory)
C....Clear all records
Q...Quit
You must add (1) additional menu option that you ch
oose.
It may be a menu option that allows the
inventory to be modified. i.e. add inventory quanti
ties, change price/cost, change dates, etc.
•
You will use structs and an array to organize the d
ata in the program. Your struct must contain at
least the following kinds of information:
o
Minimum of 2 strings (character arrays)
Suggestions include: item name, manufacturer, etc
o
Minimum of 2 integers – 1 must be product id
Product id, qty in stock
o
Minimum of 2 double values
Suggestions include: cost, price, average inventory
:
•
When you add new item the program will ask the user
for each of the fields on a separate line.
•
When you delete an item from inventory the program
will ask you for the integer id of the entry to
be deleted, locate the entry in the array and remov
e all of the data for that entry. – The list does n
ot
need to be sorted – to remove an entry, you may mov
e the last item in the list to the location of the
deleted entry
•
When you display the records on the screen, all of
the information stored for each entry will be
labeled and displayed.
•
Creating a current inventory report copies the curr
ent entries in the array to an output file. This mu
st
include labeling all of the information so that it
is clear what information is being provided.
•
Clearing the records deletes all of the information
in the array.
COP2220 – Assignment 4
Instructions:
•
You should use
at least 8 user-defined functions
(plus main) to appropriately break the problem up
into smaller pieces.
•
Your program must start up with at least 5 valid re
cords. These records must be “hard coded” in
your program file. (This can be done in one of your
user-defined functions)
•
You should use function prototypes and NO global va
riables.
This is the sample output:
Sample output:
Hello and welcome. This program helps you create an
inventory for skate shoes.
To get you started, 5 shoes have already been enter
ed.
