// Marian Basting takes in small sewing jobs. // She has two files sorted by date. // (The date is composed of two numbers -- month and year.) // One file holds new sewing projects // (such as "wedding dress") // and the other contains repair jobs // (such as "replace jacket zipper"). // Each file contains the month, day, client name, phone number, // job description, and price. // Currently, this program merges the files to produce // a report that lists all of Marian's jobs for the year // in date order. // Modify the program to also display her total earnings // at the end of each month as well as at the end of the year.
