Data Structures (CIS M. Lowenthal ASSIGNMENT1-BEVIEW The "ABC Hardware Company has hired you to wrte a program for It's Accounts Receivable department (AR a accounts that owe money to the company because they have purchased tems and have not yet paid torthem There are two types of Input data 1) A master file in ascending order by customer number (austomer numbers are 4 dgits lonc) contains a The tle aho 20 character customer name and a balance due. 2) A transaction file that contains records of each transaction. This le Iis aiso in ascending order by oustomer number There should be more than one transaction record per master record. Each related group of data in a fie is called a record. A record should be stored in a structure Each record starts with a character, "O for order or "P" for payment. Esch reco customer number, a four-digit transaction number, and up to three more also contains the tour-digit values: If the code is "O", the record contains the Rem ordered (20 charactens), the quanthy ordered (an Integer) plus the cot of the Item. (You must multiply to get the total cost) If the code is "P", the record contains the amount of the payment. You are to read in records one at a time from the two files and use the transaction file records to updae the master file. Process all transaction records for each master record belore going on to the next master record. If the transaction record contains an "O" in column 1, caloulate the order amount and add t to the balance due. f the record contains a "P" in column 1, subtract the payment from the balance due. Keep a uming total of the AR Balance of ABC Company (That is the sum of the balances due for each customer. Your program should... duplicate master records or records in the transaction fle that do not appear in the master Check for errors such as file. After processing a master record and all it's transactions the program should prepare an invoice for each customer which ists the customer name, number, previous balance (balance before transactions were perfomed), al transactions, and the final balance due (balance after transactions are perlomed. The output should look something like this.. CUSTOMER NUMBER CUSTOMER NAME $ XXXXX PREVIOUS BALANCE $ORDER AMOUNT $ORDER AMOUNT PAYMENT AMOUNT $ ORDER AMOUNT ITEM ORDERED ITEM ORDERED PAYMENT TEM ORDERED TRANSACTION TRANSACTION TRANSACTION# TRANSACTION# Don't foroet, pavments reduce the balance and orders increase it. You are to create your own data using at least 7 customers with an average of 5 transactions each. $ XXxxx BALANCE DUE
