Loyalty Program Qualification Algorithm

Implement an algorithm to check if a customer qualifies for a 20% discount based on spending over R600 and having a valid pensioner's card. The algorithm efficiently checks two criteria and provides clear qualification outcomes.

Prompt

Mr. Gucci would like to implement a pensioners loyalty program at ExecuFashions.
If a patron has a valid pensioner’s card and they spend more than R600 at the
shop, the application will display a message that the customer qualifies for 20%
discount.
Draw a flowchart that will represent the logic above

Answer

Problem Description Analysis

Mr. Gucci wants to implement a loyalty program at ExecuFashions where pensioners who spend more than R600 and have a valid pensioner's card qualify for a 20% discount. This requires checking two conditions: having a valid pensioner's card and spending more than R600.

Solution Recommendations

  1. Algorithm:
    • Input: Pensioner's card validity status, total amount spent.
    • Output: Qualification for a 20% discount.
    • Pseudocode:
      If pensioner's card is valid:
          If total amount spent > R600:
              Display message: Customer qualifies for a 20% discount.
          Else:
              Display message: Customer does not qualify for discount.
      Else:
          Display message: Customer does not qualify for discount.

Justification of Recommendations

  1. Algorithm Justification:
    • This algorithm checks both conditions sequentially, ensuring that a customer qualifies for the discount if and only if they meet both criteria.
    • By using simple if-else statements, the algorithm is easy to understand and implement.
    • The algorithm is efficient in terms of time complexity as it processes each condition only once, making it suitable for real-time applications like point of sale systems.
    • This algorithm is versatile and can be easily adapted to similar scenarios where multiple conditions need to be checked before taking action.
