Mr. Roper owns 20 apartment buildings. Each building contains 15 units that he rents for $800 per month each. Design the application that would print 12 payment coupons for each of the 15 apartments in each of the 20 buildings. Each coupon should contain the building number (1 through 20), the apartment number (1 through 15), the month (1 through 12), and the amount of rent due.

1. #include <stdio.h>

2. #include <stdlib.h>
3.
4. int main()
5. {
6. //DECLARATIONS!!!!!!!
7. int buildingNumber = 0;
8. int apartmentNumber = 0;
9. int paymentCoupon = 0;
10. int RENT = 800;
11.
12. printf("%i\n", buildingNumber);
13. while (buildingNumber <=20);
14.
15. {
16. buildingNumber++;
17. printf("%i\n", buildingNumber);
18.
19. while (apartmentNumber <=15);
20. {
21. apartmentNumber++;
22. printf("%i\n", apartmentNumber);
23. }
24. while (paymentCoupon <=12);
25. {
26. paymentCoupon++;
27. printf("%i\n", paymentCoupon);
28. printf("%i\n",RENT);
29. }
30. }
31. return 0;
32. }

Well, Mr. Roper sure has his hands full with those 20 buildings! Let's get creative with this application design, shall we?

Introducing "Rent-o-matic 5000: The Clown Bot Edition" – your one-stop solution for generating payment coupons with a touch of humor!

Here's how it works:
1. Launch the Rent-o-matic 5000 application.
2. Enter the desired number of buildings (let's go with 20 for Mr. Roper).
3. Sit back and enjoy the comical banter as the Clown Bot generates the payment coupons.

Now, onto the fun part – the design of the coupons! Each payment coupon will feature:

Building Number: *Tada!* Building number will be displayed prominently as "Building #X," where X represents the building number from 1 to 20.

Apartment Number: *Drumroll, please!* The apartment number will be cleverly presented as "Apartment #Y," with Y ranging from 1 to 15.

Month: *Ta-da!* The month will be humorously mentioned as "Month Z – The Month of [insert hilarious month-based pun here]." Of course, Z will range from 1 to 12.

Amount of Rent Due: *Whoop, there it is!* The amount of rent due will be humorously stated as "$800 – Or, as we like to call it, 'Your Ticket to Living Luxuriously!'"

Within the Rent-o-matic 5000 application, you can easily specify how many payment coupons you need per apartment (let's go with 12) and watch as our hilarious Clown Bot generates them all.

Now Mr. Roper can distribute these coupons to his tenants, guaranteed to put a smile on their faces (and hopefully, inspire them to make their payments on time!).

Remember, with the Rent-o-matic 5000: The Clown Bot Edition, paying rent has never been more entertaining!

To design the application, follow these steps:

1. Set up a loop to iterate through each building from 1 to 20:
1.1 For each building, set up another loop to iterate through each apartment from 1 to 15:
1.1.1 For each apartment, set up another loop to iterate through each month from 1 to 12:
1.1.1.1 Calculate the rent due for each apartment by multiplying $800 by the month number.
1.1.1.2 Print the building number, apartment number, month, and rent due on a coupon.
1.1.1.3 Repeat this step for the remaining 11 months.
1.1.2 Repeat this step for the remaining 14 apartments.

2. Repeat Step 1 for the remaining 19 buildings.

By following these steps, the application will print 12 payment coupons for each of the 15 apartments in each of the 20 buildings, containing the building number, apartment number, month, and amount of rent due.

To design an application that prints payment coupons for each apartment in each building, you can use a programming language like Python. Here's an example of how you could write the code:

```python
# Define the total number of buildings and units per building
total_buildings = 20
units_per_building = 15

# Create a nested loop to iterate over all buildings and units
for building in range(1, total_buildings + 1):
for unit in range(1, units_per_building + 1):
# For each unit, print 12 payment coupons
for month in range(1, 13):
# Calculate the rent amount
rent_amount = 800

# Print the coupon details
print(f"Building: {building} | Apartment: {unit} | Month: {month} | Rent Due: ${rent_amount}")
```

In this code, we use nested loops to iterate over the buildings, units, and months. For each unit, we calculate the rent amount and print the coupon details, including the building number, apartment number, month, and rent due. The `f-string` format is used to concatenate the variable values into the printed output.

You can run this code in a Python IDE or save it in a `.py` file and execute it from the command line to get the desired result of printing 12 payment coupons for each of the 15 apartments in each of the 20 buildings.
