Part 2: Implement new requirements. Problem Description A bike race registration application program is needed to support different fundraising events. For example, CU Boulder sponsors the Buffalo Bicycle Classic | University of Colorado Boulder to raise funds. A business wants to create a program to manage bike ride fundraisers for organizations to raise funds. The admin after logging in can set up the bike ride fundraiser by entering the organization name, race price and percentage of sales that goes to the organization. Next customers can register for the race by registering name, optional jersey and making a payment. The admin will be able to shut down the sales mode when login is correct to get a summary of the number of registrants and total funds raised for an organization. Requirements: User Stories and Acceptance Criteria User Story 1: Admin Set Up The admin will enter the correct pin to set up the race information. The admin can set up more than one fundraising organization where the information is stored in a structure. The admin will enter the information for the organization and continue adding more until they are done. 1.1 Login Admin enters login. Acceptance Criteria 1.1 Prompt “Enter admin pin to set up race information”. · When the passcode is not B!k34u, display error and repeat the prompt for the pin again but no more than three times. “Error: the password is incorrect” · After three incorrect attempts, give a message “Exiting admin set-up” and the program ends. · When valid passcode B!k34u display: “Set up the fundraising information for the organization. 1.1.1 Add Multiple Organizations Prompt for the information in 1.2 to 1.5. Then ask if they want to add another organization. Acceptance Criteria · Organization information should be stored alphabetically in a linked list by the name of the organization. · The admin will not be removing any organizations · Organizations can be added only during set-up · After the admin enters one organization prompt (y)es or (n)o if they want to add another. · You can use the same min and max values when validating input for each organizations. 1.2 Organization Name Admin enters the organization name. No need to do any validation. · Prompt Name: “Enter fundraising organizations name.” 1.3 RideDistance Set up race distance Acceptance Criteria · Prompt Miles: “Enter distance in miles for the bike course.” · If the distance in miles entered isn’t inclusively from 1 to 200. Repeat prompt and display error “Error: Enter a value from 1 to 200” 1.4 Ride Cost Set up ride cost Acceptance Criteria · Prompt Ride Cost: “Enter the registration cost of the bike ride for [NAME OF ORGANIZATION].” · If the race cost entered isn’t inclusively between $50 and $250. Repeat prompt and display error “Error: Enter a value from 50 to 250” · If a valid value entered, display “The bike race cost is $[COST OF RACE]” 1.5 Jersey Cost Set up jersey cost Acceptance Criteria · Prompt sales jersey price: “Enter sales price of jersey for [NAME OF ORGANIZATION].” · If the jersey cost entered isn’t inclusively between $50 and $150. Repeat prompt and display error “Error: Enter a value from 50 to 150” · If a valid value entered, display “The bike jersey cost is $[COST OF JERSEY]” 1.5 Charity Percentage Set up charity percentage Acceptance Criteria · Prompt to enter percentage: “Enter percentage of the bike race sales that will be donated to [NAME OF ORGANIZATION].” · If the race cost entered isn’t inclusively between %5and %30. Repeat prompt and display error “Error: Enter a value from 5 to 30” · If a valid value is entered, display “You entered [PERCENT] % of the bike race to go to charity.” 2. Bike Registration Mode The race registration mode will repeat until the admin quits and logins in to end registration mode. The registrant enters the organization name to register for the bike ride. Then they enter their name to register for a race, get a jersey, make payment and get a receipt. 2.0.1 Select Organization Registrant selects the organization they want to register for the bike ride. Acceptance Criteria · Display the following information for each organization and prompt the user to enter the organization name to register for that ride. You can register for one of the following bike races and a percentage will be raised for that organization. Organization Distance Cost Percentage Mattersville 100 miles $100.00 %10 ALS-Pedals 75 miles $80 %20 Enter the name of the organization you want to register. · If the name they enter doesn’t match any of the organizations, repeat the question. NOTE: I want you to focus on the new concepts with linked lists and files so the shutdown mode is still associated with a sentinel value when prompted to enter the registrant's name 2.1 Registration Name · Prompt “Enter your first name and last name to register for the ride”. · If “quit” is not entered for the name go to jersey selection 2.2 · If the admin enters “quit” ask for login, Prompt “Enter admin pin”.
