Question

A walking club maintains a master file that contains a record for each of its members. Fields in the master file include the walker's ID number, first name, last name, and total miles walked to the nearest one-tenth of a mile. Every week, a transaction file is produced. It contains a walker's ID number and the number of miles the walker logged that week. Design logic for a program that matches master and transaction file records and updates the total miles walked for each club member by adding to the cumulative total. Not all walkers submit walking reports each week. The output is updated master file and an error report that lists any transaction records for which no master record exists.
