Question

Create a class called College that has:

• At least 2 constructors (one should be the default constructor)
• All members private
• The relevant setters and getters
• A print_me() function
• A college_ID member (unique)

Write two unsorted lists that manage the data for colleges and their ranking:

• An unsorted list using an array
• An unsorted list using a linked list

Each college will have a unique ID number that will be used for search.

For the lab you don't need to read the commands from a file. Your commands will be hard-coded as function calls within your main() function.

The following actions will be performed twice: once with the array and once with the linked list. Make sure your code is clearly marked with comments, so the grader can easily see which actions were performed with each structure.

• Add 5 colleges
• Print your list of colleges
• Remove 2 colleges
• Search for a college by college ID (it will print all the information about the college)
• Print your list of colleges
• Add 4 more colleges
• Change the info in 1 college
• Change the info in 1 college
• Print all colleges
• Add one more college
• Print all colleges
