Ok, so here is the instructions that I have:

Do not use arrays or tables, functions are not required. I am providing you a file called Stock.txt that contains information regarding the 9 different stock items carried by Thrifty Dollar Inc. The file is a repeating sequence of three records such that the first record represents an item code number, the second record represents the description of each item and the third record contains the current selling price. Then the sequence repeats. Your program is to simulate the checkout register allowing the check out clerk to input item codes to obtain the current selling prices and descriptions. If an incorrect code is entered, the clerk should be notified by an appropriate message on the screen. If the item is found, the clerk will enter the number of items with that description and price and continue to the next item. When all items have been entered the clerk terminates the transaction by entering an item code of 0 (zero). The program will build a sales slip called Sales.txt enumerating the item code, description, unit price, quantity purchased, and total extended price. The bill will be subtotaled and an 8% sales tax added for a final total. Amount tendered by the customer and change given will be finally added to the invoice. This invoice should be written out to an output file called Sales.txt. The final total and change should appear on the screen as well. Your output file should line up all columns and output formatted for dollars and cents on money amounts, usingsetprecision, showpoint, and fixed. Make sure you format your output to the screen as well. This assignment uses file processing found in chapter 5. Do not use arrays or tables.

I have the majority of it written, but I can not figure out how to get it to read from the Stock.txt file correctly. I believe I need to use a FOR LOOP, but I can't figure out how to read the three lines together by the 9 items on the list.

This is what I have so Far:

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

PSEUDOCODE:

PROGRAM: Issue a receipt file (sales.txt) based off customer responses from stock.txt file

INPUTS: stock.txt file, customer responses

OUTPUTS: item number, item description, item price, line price, subtotal, tax, final total, change

FORMULAS: extended price of item = quantity purchased * unit price, subtotal = line price + each line price,

tax = subtotal * tax rate, final total = subtotal + tax, change = amount tendered - final total

start

open output file

item found = no

total = 0

get item number from user

REPEAT while item number is not 0

open stock.txt file

found = no

REPEAT 9 times

read 3 values (item number, description, price)

IF user's item number = number

display item number, description, price to the screen

ask user how many he would like to purchase

calculate the subtotal

add subtotal to total

write item number, description, quantity and subtotal to output file

found = yes

END-IF

END-REPEAT

IF found is still no

write error message to screen

END-IF

found = no

close input file

get next item number from customer

END-REPEAT

calcuate tax and display

add tax to total

display total

ask for money tendered

REPEAT while money tendered < total

display message asking for more money

get more money from customer

add money to money tendered

END-REPEAT

calculate change and display

write tax, total, money tendered, and change to output file

close output file

stop
