EECS 1510 Object Oriented Programming
Project 6 – Inventory, Stock Management
130 Points Due in class Thursday April 14, 2016
Note: This project may NOT be done in pairs.
Consider a program to enter codes of one to eight characters along with an
associated item number and associated notes. A code can represent an item, package,
or product’s name.
By using such a program, we could enter product quantities and additional notes
(i.e. storage considerations) before associating them with some brief code (i.e. string),
which would indicate the product’s ID. We could then retrieve a product’s information
by entering the product’s ID. This might be a useful application for a small store’s
inventory and stock management.
Codes are entered as 1 to 8 characters.
Use "e" for enter, "f" for find, "l" for list, "q" for quit.
Command: e Soda
Enter quantity: 20
Enter notes:
Command: e Milk
Enter quantity: 10
Enter notes: Chilled storage
Command: e Chips
Enter quantity: 25
Enter notes: Easily crushed
Command: f Milk
-- Milk
-- 10
-- Chilled storage
Command: f Popcorn
** No entry with code Popcorn
Command: . . .
There is also an "l" command, which will list all entries on the screen.
For the input to this program, upper and lower case letters are considered
equivalent. For example, if a product name with the code "Soda" is entered,
then the codes "SODA", "soda", and "SOda" will all retrieve the same entry with
"Soda" associated.
The entries are to be stored in a file from run to run. When the program begins,
the entries in the file are to be read into an array. The array should allow for up to 200
entries. The inventory need not be kept in alphabetical order. You may use a simple
sequential search to retrieve entries. When the program is exited, the entries should be
stored back in a file for use when the program is run again.
Required Program Characteristics: The assignment is to write a program that
incorporates the above features. The entries in the phonebook are to be represented
with a simple class:
class Entry {
public:
string name, number, notes;
};
Use an array to store the entries. The array should allow for up to 200 entries.
Entry entryList[200];
Use a function to read the entries into the program from a file, and a function to store
the entries back into the file when the program is exited.
void readInventory ()
void storeInventory ()
Also, use a function to list all contacts:
void listAllEntries()
Final Submission:
• In the printouts of the sample runs, each of the commands "e", "f", "l" and "q"
should be illustrated.
• You must also show that the external file is updated with entries added from a
previous run.
Note: You may wish to use
string strToUpper (string S) {
for (size_t i=0; i < S.length(); i++)
S[i] = toupper(S[i]);
return S;
}
Writing to a File
void storeInventory () {
fstream F("PhoneData.txt");
rec_num = 0;
while (rec_num < num_entries){
F << inventoryList[rec_num].name << " "
<< inventoryList[rec_num].quantity << " "
<< inventoryList[rec_num].notes << " " << endl;
rec_num++;
}
cout << "Inventory stored." << endl;
return;
