Question

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). 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 in ID number order.

Answer 1

To merge the summer and winter program files and create a list of participants in ID number order, read both files in participant ID number order, compare the ID numbers, and add the participant's first and last names to a merged list.

Step-by-step explanation:

To merge the files for the summer and winter programs and create a list of participants' first and last names in ID number order, you can use the following logic:

1. Read the summer program file and winter program file, both of which are in participant ID number order.
2. Initialize an empty list to store the merged data.
3. Compare the participant ID numbers in both files.
4. If the ID number in the summer program file is smaller, add the participant's first and last names to the merged list and read the next line from the summer program file.
5. If the ID number in the winter program file is smaller, add the participant's first and last names to the merged list and read the next line from the winter program file.
6. If the ID numbers are the same, add the participant's first and last names to the merged list and read the next line from both files.
7. Repeat steps 3-6 until all lines from both files have been processed.
8. Output the merged list of participants' first and last names in ID number order.
