Retail Outlet Managment System

I need an aid for my unfinished programming.

It's due on midnight yesterday(11/10/07), so I lost a lot of points from this(maybe lost 70 out of 100). I cannot make up for this lost points, I think. Please somebody help me how to make my program run because it has a lot of error messages. I have updated followings today.

Code:

#include <stdio.h> #include <stdlib.h> #include <ctype.h> #define MAX_TBL_SIZE 30, MIN_STOCK_LEVEL 10 int index, number, input_item_id, input_item_stock, ItemId, Stock, Sufficient, qty_sold, qty_new, input_item_id;; float UnitPrice; char file_name[100]; int num, r, c; void ActionCode(int [8]); void input(int input_item_id[index], int input_item_stock[index], float UnitPrice[index]); void CURRENTSTATUS(int ItemId[index], int Stock[index], int UnitPrice[index], char Sufficient); int main(void) { FILE *ifp; fprintf(stderr, "Enter the name of the input file: \n"); fscanf(ifp, "%d", &num); ifp = fopen("file_name", "r"); ActionCode([8]); input(input_item_id, input_item_stock, UnitPrice); CURRENTSTATUS(ItemId, Stock, UnitPrice, Sufficient); system("PAUSE"); return 0; } void input(int input_item_id[index], int input_item_stock[index], float UnitPrice[index]){ while(input_item_id[index] != 0 && input_item_stock[index] != 0 && UnitPrice[index] != 0){ fscanf(ifp, "%d", &input_item_id[index]); fscanf(ifp, "%d", &input_item_stock[index]); fscanf(ifp, "%f", &UnitPrice[index]); index++; } void CURRENTSTATUS (int ItemId[index], int Stock[index], int UnitPrice[index], char Sufficient){ if(input_item_stock < MIN_STOCK_LEVEL) fprintf(stdout, "No", &Sufficient); else fprintf(stdout, "Yes", &Sufficient); fprintf(stdout, "CURRENT STATUS\n"); fprintf(stdout, "Id\tStock\tPrice\tSufficient\n"); fprintf(stdout, "%d\t%d\t%.2f\t%c\n", ItemId[index], Stock[index], UnitPrice[index], Sufficient); void ActionCode(int *){ int [8] = {1, 2, 3, 4, 5, 6, 7, 8}; while ((c =fgetc(ifp)) != EOF) { int number=1; switch (number){ while(number != 0){ case 1: CURRENTSTATUS(ItemId, Stock, UnitPrice, Sufficient); break; case 2: if(Stock[index] == 0) fprintf(stdout, "There is no item with id %d.\n", ItemId[index]); break; case 3: fprintf(ofp, "After sale, there are %d items with id %d.\n", qty_sold, ItemId); if(qty_new < MIN_STOCK_LEVEL){ fprintf(stdout, "This product needs to be reordered.\n"); } break; case 4: /* input_item_id == 1 */ fprintf(ofp, "After purchase, there are %d items with id %d.\n", qty_new[index],ItemId[index]); if(qty_new < MIN_STOCK_LEVEL){ fprintf(stdout, "This product needs to be reordered.\n"); } break; case 5: if(qty_new < MIN_STOCK_LEVEL){ fprint(stdout, "Items to be reordered\n"); fprint(stdout, "%d\n", ItemId[index]); } break; case 6: if (qty_new <= 1){ printf("Lowest Stock: Only %d items left with id %d.\n", qty_new[index], ItemId[index]); fprintf(stdout, "URGENT ORDER - this product needs to be"}; fprintf(stdout, "re-ordered\n"); fprintf(stdout, "immediately.\n"); } break; case 7: Unitprice[index] += (Stock[index]) * (UnitPrice[index]); UnitPrice[index] += (Stock[index]) * (UnitPrice[index]); fprintf(stdout, "Total price of all the items: $.2f\n", UnitPrice[index]); break; case 8: fprintf(stdout, "Good Bye!\n"); break; } } } }

Objectives:

To learn concepts of file handling and array manipulation.

Description:

In this assignment, it is desired to develop a retail outlet management system.

Every item handled by the outlet is given a unique id. The system should have

provision to record price and stock of each item. You need to read the

information on id (integer), stock (integer) and price (float) for various items

from the input file and store these in three separate arrays.

The outlet does not wait for an item to be exhausted before reordering. As soon

as the item stock goes below a satisfactory level, it is reordered.

You need to develop separate functions to carry out various actions. The

original inventory and the various actions to be carried out will be read from

an input file. The various actions are indicated through the action codes

described below:

Action code: 1
action desired: Generate report on all items
Print the contents of the three arrays. Each output line should contain the item
id, its stock level, unit price of the item, and an indication of whether or not
there is sufficient level of that item in stock.

action code: 2
action desired: Generate report on one specific item
For the given item id, print out the quantity (stock) and the unit price of that
item.

action code: 3
action desired: Selling
For the given item id, reduce the stock level of the item by the number of items
sold.

action code: 4
action desired: Purchasing
For the given item id, increase the stock level of the item by the quantity
purchased.

action code: 5
action desired: Order
List out the ids of the items which need to be reordered.

action code: 6
action desired: Urgent-order
List the item that must be ordered immediately (one whose stock is the lowest).
Assume that there will be exactly one such item.

action code: 7
action desired: Total retail
Print the total value of all the items put together (multiply unit price of each
item with its stock and total up everything).

action code: 8
action desired: Exit
Print "Good Bye!" and terminate the program.

The Input File

Prompt the user to enter the name of the input data file. It is guaranteed that
the user will enter a valid file name. The file starts with information about
the various items in the retail outlet.

Each line will contain information for one item in the following order:
item id (positive integer),
stock (positive integer)
and unit price (positive float).

It is guaranteed that the retail outlet will not have more than 30 items.
(#define MAX_TBL_SIZE as 30 and declare each of your three arrays to be of size
MAX_TBL_SIZE.)

As you read in the information from each line, store the values in three
separate arrays. Stop storing the values when you get to the line containing
three zeros, i.e., values provided for item id, stock and unit price are zero.
This input line signifies the end of the current inventory (situation of the
retail outlet) and you should stop storing values in the three arrays.

Assume the satisfactory stock level for each item is 10 (#define MIN_STOCK_LEVEL
as 10 and use MIN_STOCK_LEVEL throughout your program).

The remaining lines in the input file specify the actions to be carried out.
The first integer on each line will specify the desired action, followed by
other parameters if necessary. These are explained in the data processing part
which follows.

Data Processing and Output:

Once you have stored the current status of the retail store, start reading the

action lines from the input file.

As you read each line from the input file, print it out. Then perform the action

and print the output for each code, as per the format specified in the sample

output. The processing for each action code is indicated below:

1
This line will not have any other parameters. Print the current status of retail
outlet as explained in action code 1 above.

2
This line will contain one more integer which indicates an item id. Search your
item id array and when you locate input_item_id, print the item id, and its
corresponding stock and unit price. If the specified id is not found in the
item id array, then print "There is no item with id input_item_id".

3
This line will contain two more integers input_item_id and qty_sold. For the
given item, reduce qty_sold from its corresponding stock (assume the item exists
in the inventory). Print id and the new value of stock for that item. If the
item needs to be reordered, print "This product needs to be reordered".

4
This line will contain two more integers input_item_id and qty_new. For the
given item, add qty_new to its corresponding stock (assume the item exists in
the inventory). Print id and the new value of stock for that item.

5
This line will not have any other parameters. Examine the stock array, and print
the ids of items which need to be reordered.

6
This line will not have any other parameters. Examine the stock array, and print
the id for the item whose stock value is lowest of all (assume there will be
exactly one such item). If the stock level is below satisfactory, then print
"URGENT ORDER - this product needs to be re-ordered immediately".

7
This line will not have any other parameters. Perform the action outlined in
action code 7 above.

8
This line will not have any other parameters. Perform the action outlined in
action code 8 above.

Final Code

Does anyone have the final code to share i am lost

can someone please post the code for this program, its highly confusing. i have been working on this all day, it reads my file, but keeps exiting doesn't show the info from the retail.txt file. someone please post the code and show some light on this program. thanks
