Laramie Park District has files of participants in its summer and winter programs this year. Each file is in participant ID number order and contains additional fields for first name, last name, age, and class taken (for example, Beginning Swimming).
a. Design the logic for a program that merges the files for summer and winter programs to create a list of the first and last names of all participants for the year.
b. Modify the program so that if a participant has more than one record, you output the participant's name only once.
c. Modify the program so that if a participant has more than one record, you output the name only once, but you also output a count of the total number of classes the participant has taken.
