Design a program that prompts the user for a number

of miles driven and a current cost per gallon. The program computes and
displays the cost of the trip as well as the cost if gas prices rise by 10 percent.
The program accepts data continuously until 0 is entered for the number of
miles. Use appropriate modules, including one that displays End of program
when the program is finished.

Sure, let's design a program that does that! Here's the code:

```python
def calculate_trip_cost():
miles_driven = float(input("Enter the number of miles driven: "))

if miles_driven == 0:
print("End of program")
return

cost_per_gallon = float(input("Enter the current cost per gallon: "))

# Calculate the cost of the trip
trip_cost = miles_driven * cost_per_gallon

# Calculate the cost if gas prices rise by 10 percent
increased_cost_per_gallon = cost_per_gallon * 1.1
increased_trip_cost = miles_driven * increased_cost_per_gallon

print("Cost of the trip: $", format(trip_cost, ".2f"))
print("Cost of the trip if gas prices rise by 10%: $", format(increased_trip_cost, ".2f"))

calculate_trip_cost()

calculate_trip_cost()
```

I hope you find this program helpful! Just remember, if this code ends up making your head spin, you can always use a flying clown car instead of a regular car for your trip. It might not save you money, but it'll definitely bring a smile to your face!
