Cash Register Basic Steps in Creating your Program

1. Plan your logic before working on the project and review the syntax you will use in the project. Think about how you want the lines of output to be displayed to the user. You will want to tell the user what the program does and what type of input you expect from the user (Introduction to the User). Select names of the variables you will use in the program.

2. Create a C++ project in Visual Studio 2012. And have the code window open to write the project code. Display Using Visual Studio to create your program in C++ and follow the instructions on creating the project.  Declare variables to hold information about tank capacity and mpg

 Set up information about this program and what the user will enter and results expected

 Ask the user to enter some information requested and save the response to a variable. Make sure the position for the user to enter information is on the same line as the request for information.

 Use line spacing (endl or \n) to separate lines of output to make it easy for the user to read the information.

3. Documentation: All lines of code must be documented.

 Use the syntax to designate lines in code as comments (//)

 These comments can be at the end of a line of code or in a group definition at the beginning of a section of code. All methods and function need a group heading document.

4. Run the program using Ctrl+F5. Debug the code, making sure all calculations are correct and the line spacing is suitable for readability.

Your program Assignment Design a CashRegister class that can be used with the Inventory Item class discussed in the chapter.

The CashRegister class should perform the following:

1. Ask the user for the item and quantity being purchased.

2. Get the item’s cost from the Inventory Item object.

3. Add a 30% profit to the cost to get the item’s unit price.

4. Multiply the unit price times the quantity being purchased to get the purchase subtotal.

5. Compute the 6% sales tax on the subtotal to get the purchase total.

6. Display the purchase subtotal, tax and total on the screen

7. Subtract the quantity being purchased from the on Hand variable of the Inventory Item class object. Implement both classes in a complete program. Feel free to modify the Inventory Item class in any way necessary. Be sure and loop the program so that multiple items can be purchases Input Validation: Do not accept a negative value for the quantity of items being purchased.

(in C# please.) EXCEPTION HANDLING Concept Summary:

1. Use of try… catch in a program

2. Define an exception class and call it from the driver program.

For this lab you will complete two parts.

Part (a) of the lab implements try… catch and uses an existing exception in C# or in Java.

Write a program that implements an ArrayIndexOutOfBounds error.

Part (b) writes a program that converts a time from 24-hour notation to 12-hour notation.

Assume the user will enter the time as a 4-digit number with no colon.

Submission Guidelines: You will turn in 3 program files. Part (a) has one program file Part (b) requires two program files. (Note: C# Students can turn in one program file)

Specifications: Part (a): Write a program in Java or C# that declares an array of 5 elements and displays the contents of the array. Your program should attempt to access the 6th element in the array (which does not exist) and using try.. catch your program should prevent the run-time error and display your error message to the user. Sample output including error message is provided below. SAMPLE OUTPUT: Part (a) Printing an element out of bounds 5 7 11 3 0 You went out of limits in the array

Part (b): Define an exception class called InvalidTimeFormatException. If the user enters an invalid time like 1065 or 2515, the program should throw and handle an InvalidTimeFormatException. NOTE: Assume the user will enter the time as a 4-digit number with no colon.

SAMPLE OUTPUT:

Part (b) Enter time in 24-hour notation: 1614

That is the same as 4:14 PM Again? (y/n) y

Enter time in 24-hour notation: 0245

That is the same as 2:45 AM Again? (y/n) y

Enter time in 24-hour notation: 1215

That is the same as 12:15 PM Again? (y/n) y

Enter time in 24-hour notation: 2612 Error: Hour can only be between 0 and 23 Again? (y/n) y

Enter time in 24-hour notation: 1562 Error: Minutes can only be between 0 and 59 Again? (y/n) n

The Account class Create a class named Account, which has the following private properties: number: long...

The Account class

Create a class named Account, which has the following private properties:

  • number: long
  • balance: double

Create a no-argument constructor that sets the number and balance to zero.

Create a two-parameter constructor that takes an account number and balance.

First, implement getters and setters: getNumber(), getBalance(), setBalance(double newBalance). There is no setNumber() -- once an account is created, its account number cannot change.

Now implement these methods: void deposit(double amount) and void withdraw(double amount). For both these methods, if the amount is less than zero, the account balance remains untouched. For the withdraw() method, if the amount is greater than the balance, it remains untouched.

Then, implement a toString() method that returns a string with the account number and balance, properly labeled.

The SavingsAccount class

This class inherits from Account and adds a private apr property, which is the annual percentage rate for interest. Write a no-argument constructor that sets the account number, balanace, and APR to zero. Write a three-argument constructor that takes an account number, balance, and interest rate as a decimal (thus, a 3.5% interest rate is given as 0.035).

Modify toString() to include the interest rate.

Add a getter and setter method for apr. The setter should leave the APR untouched if given a negative value.

Write a calculateInterest() method that returns the annual interest, calculated as the current balance times the annual interest rate.

The CreditCardAccount class

This class inherits from Account and adds a private apr property, which is the annual interest rate charged on the balance. It also has a private creditLimit property (double) which gives the credit limit for the card. Write a no-argument constructor that sets all the properties to zero. Write a four-argument constructor that takes an account number, balance, interest rate as a decimal (thus, a 3.5% interest rate is given as 0.035), and credit limit. Write getters and setters for the apr and creditLimit.

Modify toString() to include the interest rate and credit limit.

Override the withdraw() function so that you can have a negative balance. If a withdrawal would push you over the credit limit, leave the balance untouched. Examples:

  • If your balance is $300 with a credit limit of $700, you can withdraw $900 (leaving a balance of $-600).
  • If your balance is $-300 with a credit limit of $700, you can withdraw $350 (leaving a balance of $-650).
  • If your balance is $-300 with a credit limit of $700, you can not withdraw $500, because that would then owe $800, which is more than your $700 limit.

In short, the maximum amount you can withdraw is your current balance plus the credit limit.

Add a calculatePayment() method that works as follows:

  • If the balance is positive, the minimum amount you have to pay on your card per month is zero.
  • Otherwise, your monthly payment is the minimum of 20 and (???/12)⋅(−???????)(apr/12)⋅(−balance)(???/12)⋅(−???????)(apr/12)⋅(−balance)

The Test Program

Write a program named TestAccounts that creates an array of five Account objects:

  • An Account number 1066 with a balance of $7,500.
  • A SavingsAccount number 30507 with a balance of $4,500 and an APR of 1.5%
  • A CreditCardAccount number 51782737 with a balance of $7,000.00, APR of 8%, and credit limit of $1000.00
  • A CreditCardAccount number 629553328 with a balance of $1,500.00, an APR of 7.5%, and a credit limit of $5,000
  • A CreditCardAccount number 4977201043 with a balance of -$5,000.00, an APR of 7%, and a credit limit of $10,000

Your program will use a loop to do the following for each account:

  • Deposit $2,134.00
  • Withdraw $4,782.00
  • Print the account status using toString().
    • For savings accounts, also display the annual interest
    • For credit card accounts, also display the monthly payment

Here is some sample output:

Account: 1066
Balance: $4852.00

Account: 30507
Balance: $1852.00
Interest Rate: 1.50%
Annual Interest: $27.78

Account: 51782737
Balance: $4352.00
Interest Rate: 8.00%
Credit Limit: $1000.00
Monthly Payment: $0.00

Account: 629553328
Balance: $-1148.00
Interest Rate: 7.50%
Credit Limit: $5000.00
Monthly Payment: $7.18

Account: 4977201043
Balance: $-7648.00
Interest Rate: 7.00%
Credit Limit: $10000.00
Monthly Payment: $20.00


Put the Account, SavingsAccount, and CreditCardAccount classes in the TestAccounts.java file rather than creating separate files. Please submit only one file. Upload the TestAccounts.java file here.

Use Python program.

  1. Make a list called groceries with the following values: "pineapple", "tangerine", and "peach".
  2. Define these two dictionaries in your program:

stock = {

    "pineapple": 6,

    "peach": 0,

    "tangerine": 32,

    "pear": 15

}

prices = {

    "pineapple": 4,

    "peach": 2,

    "tangerine": 1.5,

    "pear": 3

}

  1. Take one argument “item” as input from the user and returns the cost of that item. Assume the user will only input an item that exists.
  2. Change the program now so that it takes two separate inputs from the user, ‘item’ and ‘quantity’, and return the cost of that quantity of items. If there are not enough items available, return an appropriate message indicating the quantity that is available, and what that cost is. If the user asks for an item that doesn’t exist, print a message so indicating, and end the program.
  3. Change your program so that it presents the user with a menu of options; ‘enter item and quantity’ and ‘quit’. Cause the program to continue asking for an item and quantity until the user decides to end the program. Apply the same rules as in ‘b’, but each time you return a cost, reduce the amount of available stock by that amount.

This exercise is a bit more complicated and will be a review of what we’ve learned about lists and dictionaries. The aim of this exercise is to make a gradebook for a group of students.

Follow these steps:

  1. Consider a list of dictionaries in the following format:

students = {

"lloyd": {

"name": "Lloyd",

"homework": [90.0,97.0,75.0,92.0],

"quizzes": [88.0,40.0,94.0],

"tests": [75.0,90.0]

},

"alice": {

"name": "Alice",

"homework": [100.0, 92.0, 98.0, 100.0],

"quizzes": [82.0, 83.0, 91.0],

"tests": [89.0, 97.0]

},

"tyler": {

"name": "Tyler",

"homework": [0.0, 87.0, 75.0, 22.0],

"quizzes": [0.0, 75.0, 78.0],

"tests": [100.0, 100.0]

}

}

  1. Pass this dictionary as a parameter to your functions, and for each student in the dictionary, output in a well-designed manner the following data:
  • name
  • homework scores
  • quiz scores
  • test scores
  • average homework scores
  • average quiz scores
  • average test scores
  • letter grade
  • assume:

      A – 100% - 90%

      B – 90% - 80%

      C – 80% - 70%

      D – 70% - 60%

      F – 59% - below

  • an average grade for the class

Your program should work for any list of students, i.e. your solution should be general in that it takes in any dictionary in this format of any length, process the data, and return the results. You should test it with this input, as well as input you make up. I will also test it with both this input as well as another set of data that is formatted similarly.
