Write a program that helps the user determine whether to buy a wooden or ornamental iron fence based on its cost. Once the user has chosen, the program will also ask the user how much money (in US dollars) he or she plans to give the cashier, and then it will calculate the correct change.
Note: You may not use conditionals to calculate the change, and you may not use any programming construct that we have not covered in class at any point in this program.
Begin by prompting the user for the length of the fence to be built. Using that information, calculate the total cost of each type of fence based on these prices:
Wooden: $16.27 per linear foot
Ornamental Iron: $37.89 per linear foot
Print the total cost for each fence.
Next, prompt the user to choose either fence number 1 or fence number 2. The user will enter either the number 1 or the number 2.
After the user has chosen, tell the user that the fence company accepts only cash, and ask the user how much cash he or she is planning to give the fence builder and then calculate the user's change. Your change should involve the fewest possible number of coins, i.e. for $.25, the change should consist of one quarter, not two dimes and one nickel. You may assume the user enters a numerical value higher than the cost.
Floating-point operations (arithmetic operations with values of type float) can result in round-off error. You need to make sure that you do not lose precision in the number of cents in your dollar amount.
Hint: Try multiplying the money amount by 100, then rounding to the nearest integer (with the round function) and casting this value to type int to get the number of cents.
cents = int(round(money*100))
Use tabs to line up the number of dollars, quarters, etc. in your output. (Reminder: you learned about a tab escape sequence!)
Your output should look like this for a fence 60 feet long:
Please enter the length of the fence: 60
The costs for the fences are:
1. $976.20 for the wooden fence
2. $2273.40 for the iron fence
Would you like fence 1 or fence 2? 1
The fence company only accepts cash.
How much money do you plan to give the fence builder? 991.54
Your change, $15.34, consists of:
