a. Design the logic for a program that merges the files for January and February to create a list of all books borrowed in the two-month period.
b. Modify the library program so that if a book number has more than one record, you output the book information only once.
c. Modify the library program so that if a book number has more than one record, you not only output the book information only once, you output a count of the total number of times the book was borrowed.
