After a week of preliminary study and review of the organization, Mr. Tung decides to implement a simple billing system for the company. Each line of the input data file for the billing system contains a name, address, transaction type, and amount of transaction separated by a "_". The transaction type is either C (for credit) or D (for debit). The transaction amount is given in dollars and cents. If we assume each person's balance is initially zero, that a credit reduces the balance, and a debit increases the balance, the computer program should produce a report, ordered on name, giving the final balance in dollars and cents in each account. If a balance is exactly zero, then that person's balance should not appear in the report.
