• Hot dogs per person (1 integer)

Due 10/21 @
11:55 PM

Program 6: Change Maker Program (60 points)
Use skills from chapters 1 - 5.
Write a program that accepts a sales amount (in dollars) and an amount tendered (in dollars) and then displays to the screen the change (in dollars) along with only the correct denominations of money returned. Your output needs to be grammatically correct (e.g., "2 quarters", "1 quarter").

A sample run is listed below. The highlighted text indicates user input.

Welcome to my Change Program

Enter the sales price (xx.xx): $3.46

Enter the amount tendered (xx.xx): $5.00



Your change is: $1.54

You will receive:

1 - Dollar Bill

2 - Quarters

4 - Pennies

• You may be off by a penny due to floating point precision errors...don't worry about that for this program.
• Using integer division or modular division on floats loses lots of grade points! Operators // and % may only be used on integers, regardless what Python actually allows.
• You must use only these denominations when making change: penny, nickel, dime, quarter, one dollar bill, five dollar bill, ten dollar bill, twenty dollar bill, fifty dollar bill, and one hundred dollar bill.

Due 10/28 @
11:55 PM

Program 7: Budget Analysis (100 points)
Use skills from chapters 1 - 6.
Write a program that asks the user to enter the amount that they budgeted for the month. A loop should then prompt the user to enter there expenses, one at a time and to enter 0 to quit. When the loop finishes, the program should display the the amount of budget left. (a negative number indicates the user is over budget and a positive number indicates the user is under budget) The program should prompt the user to run the program again. The user will enter details in the following order:

• Total amount budgeted (1 float)
• Expense amounts (unknown number of floats, 0 to quit)
• "Run again?" response (1 string, Y for "yes, run again" and N for "no, quit")

A sample run is listed below. The highlighted text indicates user input.

Enter your budget amount (xxxx.xx): $1000

Enter an expense (xxx.xx): $500

Enter an expense (xxx.xx): $200

Enter an expense (xxx.xx): $0

You are $300.00 under budget.

Would you like to do another budget? (Y/N): N

Goodbye

Another example

Enter your budget amount (xxxx.xx): $500

Enter an expense (xxx.xx): $100

Enter an expense (xxx.xx): $100

Enter an expense (xxx.xx): $400

Enter an expense (xxx.xx): $300

Enter an expense (xxx.xx): $0

You are $400.00 over budget.

Would you like to do another budget? (Y/N): Y

Enter your budget amount (xxxx.xx): $1200

Enter an expense (xxx.xx): $200

Enter an expense (xxx.xx): $100

Enter an expense (xxx.xx): $300

Enter an expense (xxx.xx): $0

You are $600.00 under budget.

Would you like to do another budget? (Y/N): N

Goodbye

• If Y is entered to run again, the same input types are entered for each additional run.
• Be careful, make sure that your program checks for captial Y.
• You must validate inputs and reject negative monetary amounts. Make the user re-enter a valid amount.
• You must define a "main" and at least two other functions for this program.

Program 8: Distance Traveled (100 points)
Use skills from chapters 1 - 6.
The distance a vehicle travels can be calculated as follows: distance = speed x time For example, if a train travels 40 miles per hour for three hours, the distance traveled is 120 miles. Write a program that asks the user for the speed of a vehicle (in miles per hour) and the number hours it has traveled. It should then use a loop to display the distance the vehicle has traveled for each hour of that time period.

The program will prompt the user to run the program again after each run. The user will enter details in the following order:

• Vehicle speed in MPH (1 integer)
• Number of whole hours traveled (1 integer)
• "Run again?" response (1 string, Y for "yes, run again" and N for "no, quit")

A sample run is listed below. The highlighted text indicates user input.

Welcome to my Distance Calculator

Enter the vehicle speed: 40

Enter the hours traveled: 3



Hour          Distance

----------------------

1                 40

2                 80

3                120

Do you want to run again? (Y/N): N

Another example:

Welcome to my Distance Calculator

Enter the vehicle speed: 20

Enter the hours traveled: 5



Hour          Distance

----------------------

1                 20

2                 40

3                 60

4                 80

5                100

Do you want to run again? (Y/N): Y

Enter the vehicle speed: 80

Enter the hours traveled: 2



Hour          Distance

----------------------

1                 80

2                160

Do you want to run again? (Y/N): N

• If Y is entered to run again, the same input types are entered for each additional run.
• You must validate inputs and reject negative speed and negative hours traveled. Require user to re-enter any bad input.
• You must define a "main" and at least two other functions for this program.

Program 9: Rock, Paper, Scissors (200 points)
Use skills from chapters 1 - 8.
Write a program to allow the user to play Rock, Paper, Scissors against the computer. The program will be menu driven (see details below). The user can continue to play the game over and over by choosing to play the game in the menu. A game consists of a single battle: win, lose, or tie. For a single battle the user makes their move and then the computer move is displayed followed by a description of who won that battle. Do not break a tie.

Once the user chooses to quit, the program then displays the win/loss/tie record for all the games just played. For example, if I chose to play 5 times and actually won 2, lost 2, and tied once out of those 5, then the final display as I chose to quit would be something like:

Human: 2, Computer: 2, Tie: 1

The user will enter the details in the following order during gameplay:

• Menu choice (1 integer, 1 to play a game, 2 to quit)
• Player's move (1 string, Rock, Paper, or Scissors)

• If the human wins, loses, or draws, the program must say "You win", "You lose", or "draw" respectively.
• The computer's move (rock, paper, or scissors) must be displayed i.e "Computer plays rock", "Computer plays scissors", or "Computer plays paper"

• From now on, you must now trap for everything that is not valid data, including incorrect data types.
• Generate computer moves using functions from Python's random module.
