,Question 1 Preview:
What this project does:
1. Unique ID Generation: The program extracted the initials "NJ" from the first and last names,
"Nick" and "Johnson," respectively. It then counted the total number of characters in the full
name (excluding spaces), which was 16 characters. The count was padded with leading zeros
to make it 4 digits, resulting in "0016." Thus, the unique ID generated was "NJ0016."
2. Initial Key Generation: For the initial key, the program randomly selected 6 characters from
the full name "Nick Johnson." It ensured that at least one character was a vowel and one was
a consonant. The selected characters were "inhkis," resulting in the initial key "inhkis."
3. Output Display: The program displayed the generated unique ID ("NJ0016") and the initial
key ("ihnkisnoicnm") using a QMessageBox, providing a visual representation of the results
to the user.
4. User Interaction: The user interacted with the program by inputting their full name ("Nick
Johnson") through a QInputDialog. The program processed this input to generate the unique
ID and initial key, demonstrating the application's adherence to the specified rules for ID and
key generation.
,Question 2 Preview:
1. User Input: The program prompts the user to input the number of items (2) and details for
each item, including ID, name, and price. Additionally, it requests details for the vendor, such
as Vendor ID, Name, and Address.
2. Item Initialization: Using the input data, the program initializes two StoreItem objects with
the specified IDs, names, and prices: "Laptop" (ID: 101, Price: $999.99) and "Smartphone"
(ID: 102, Price: $499.99).
3. Vendor Setup: The program creates a Vendor object with the provided details: Vendor ID:
201, Name: "ABC Electronics", Address: "123 Main Street."
4. Output Display: It then displays the details of each item, first without vendor information
and then with vendor details. Finally, it demonstrates the use of the getVendorName()
method to output the vendor name for each StoreItem.
