Print Library Receipt

Hi I need help with my C program to print a Library receipt using Linux with a driver program that can’t be changed and h file.
Change processTransaction:
o Receives Node **ppHead instead of the bookM array and count
o Uses searchLL to find a book in the ordered linked list.
p = searchLL(*ppHead book.szBookId &pPrecedes);
o Uses pointer notation to update the contents of a node instead of the contents of an array element
(e.g. p0>book.szCustomerId instead of bookM[i].szCustomerId)
Change processCustomerCommand:
o Receives Node **ppHead instead of the bookM array and count
o Invokes processTransaction passing ppHead instead of the bookM array and count
Change processBookCommand:
o Receives Node **ppHead instead of the bookM array and count
o Uses searchLL to find a book in the ordered linked list:
p = searchBooks(*ppHead book.szBookId &pPrecedes);
o Uses pointer notation to reference a book instead of referencing an element of the bookM array.
o Add code for the new BOOK NEW subcommand. This should sscanf the data into elements of a Book
structure (declared using Book book). It should then pass that book to insertLL.
Here is what I have so far.

/******************** printBooks **************************************
void printBooks(char *pszHeading Book bookM[] int iBookCnt)
Purpose:
Prints each book in a table format
Parameters:
I char *pszHeading Heading to print before printing the table of books
I Book bookM[] Array of books
I int iBookCnt Number of elements in the bookM array.
Returns:
n/a

void printBooks(char *pszHeading Node *pHead) {
printf(%sn pszHeading);
printBookHeading();
while(pHead != NULL) {
printBook(&(pHead->book));
pHead = pHead->pNext;
}
}
/********************processCustomerCommand *****************************
void processCustomerCommand(Book bookM[] int iBookCnt
char *pszSubCommand char *pszRemainingInput
Customer *pCustomer)
Purpose:
Processes the subcommands associated with the CUSTOMER command:
CUSTOMER BEGIN szBookId szCustomerId szCheckedOutDt dLateFeePerDay dMaxLateFee szTitle
specifies the beginning of customer request and includes all the identification information from program 2.
CUSTOMER ADDRESS szStreetAddressszCityszStateCdszZipCd
specifies the address for a customer (separated by commas)
CUSTOMER TRANS cTransType szBookId szTransDt
specifies a single book transaction. Steps:
– Print the Transaction Type Book Id and Transaction Date
– Lookup the book ID using a binary search. If not found print a warning (but do not terminate your program) and return.
– If the transaction date is invalid show a message stating invalid date but do not terminate. Use the validateDate function.
– If the transaction type is C (meaning checkout):
o If the book is already checked out show a message stating already checked out but do not terminate.
o Otherwise check out the book to this customer setting the book’s customer ID. The book’s checked out date needs to be set to the transaction’s date.
– If the transaction type is R (meaning return):
o Use dateDiff to subtract the book’s szCheckOutDt from the transaction’s szTransDt
o If the difference is more than 14:
— Determine the number of days late by subtracting 14 from that difference.
— Compute the late fee by multiplying the number of days late by the book’s dLateFeePerDay.
— If that late fee is greater than the book’s dMaxLateFee change it to dMaxLateFee.
— Print the late fee.
— Add the computed late fee to the customer’s dFeeBalance
o Set the book’s customer ID to NONE.
o Set the book’s check out date to 0000-00-00.
CUSTOMER COMPLETE
specifies the completion of a customer. Print the total fees for this customer.
Parameters:
I/O Book bookM[] Array of books
I int iBookCnt Number of elements in bookM[]
I char *pszSubCommand Should be BEGIN ADDRESS REQUEST or COMPLETE
I char *pzRemainingInput Points to the remaining characters in the input
line (i.e. the characters that following the
subcommand).
I/O Customer *pCustomer The BEGIN subcommand begins a new customer.
