Computer Science: Ticket Sales Program - IPO, Pseudocode, and Tracing

This assignment solution details a ticket sales program, addressing various aspects of software development. It begins with variable definitions, including constants for ticket prices and variables for ticket categories. The solution outlines the program's IPO (Input, Process, Output), pseudocode, and a module hierarchy to illustrate the program's structure. The pseudocode describes the main module, which calls modules to set ticket quantities and calculate the total amount generated. A flowchart visually represents the program's logic. The solution also includes a hand-tracing section, demonstrating the program's execution with sample data, showing the values of variables at each step and the corresponding output, to facilitate understanding of the program's behavior and the impact of different inputs on the final output. The problem covers fundamental programming concepts and provides a comprehensive guide to understanding and implementing a ticket sales program.

Pseudocode
Start
1. Define global constant Integer priceCategory1 = 250
2. Define global constant Integer priceCategory2 = 200
3. Define global constant Integer priceCategory3 = 150
4. Define global Integer ticketCategory1 = 0
5. Define global Integer ticketCategory2 = 0
6. Define global Integer ticketCategory3 = 0
7.
8. Module main()
9. Call setSeats()
10. Call getAmount()
11. End Module
12.
13. Module setSeats()
14. Set ticketCategory1=quantity(“Number of tickets sold of category 1“)
15.

16. Set ticketCategory2=quantity(“Number of tickets sold of category 2“)
17. Set ticketCategory3=quantity(“Number of tickets sold of category 3“)
18. End Module
19.
20. Module getAmount ()
21. Set amountGenerated = (priceCategory1*ticketCategory1) +
(priceCategory2*ticketCategory2) + (priceCategory3*ticketCategory3)
22. Display “Total income generated”,amountGenerated
23. End Module
End
