Write a class named StockPrices . The class constructor should accept an array of stock prices as its argument. The class should have a member function that returns the average of the stock prices. If any stock price in the array is negative or greater than 5000, the class should throw an exception. Demonstrate the class in a program.

The local Driver’s License Office has asked you to write a program that grades the written portion of the driver’s license exam. The exam has 10 multiple-choice questions. Here are the correct answers: 1. B 2. D 3. A 4. A 5. C 6. A 7. B 8. A 9. C 10. D A student must correctly answer 7 of the 10 questions to pass the exam. Write a class named DriverExam that holds the correct answers to the exam in an array field. The class should also have an array field that holds the student’s answers. The class should have the following methods: • passed. Returns true if the student passed the exam, or false if the student failed. • totalCorrect. Returns the total number of correctly answered questions. • totalIncorrect. Returns the total number of incorrectly answered questions. • questionsMissed. An int array containing the question numbers of the questions that the student missed, i.e. answered incorrectly. Test the class in a separate class, DriverTest , that asks the user to enter a student’s…

In previous chapters, you have created programs for the Greenville Idol competition. Now create a Contestant class with the following characteristics: The Contestant class contains public static arrays that hold talent codes and descriptions. Recall that the talent categories are Singing Dancing, Musical instrument, and Other. The class contains an auto-implemented property that holds a contestants name. The class contains fields for a talent code and description. The set accessor for the code assigns a code only if it is valid. Otherwise, it assigns I for Invalid. The talent description is a read-only property that is assigned a value when the code is set. Modify the GreenvilleRevenue program so that it uses the Contestant class and performs the following tasks: The program prompts the user for the number of contestants in this years competition; the number must be between 0 and 30. The program continues to prompt the user until a valid value is entered. The expected revenue is calculated and displayed. The revenue is $25 per contestant. The program prompts the user for names and talent codes for each contestant entered. Along with the prompt for a talent code, display a list of the valid categories. After data entry is complete, the program displays the valid talent categories and then continuously prompts the user for talent codes and displays the names of all contestants in the category. Appropriate messages are displayed if the entered code is not a character or a valid code.
This assignment uses the same account class created in Lab #4 with a more generally useful interface. It reads commands from a bank.txt file. Your program must process the followingfour commands. Create account amountDeposit account amountWithdraw account amountBalance account In all of the above commands, account is an integer and amount is a double. The following program behavior is required –1. Valid account numbers are 1-9. This requires the program to have an array of references to Account objects.2. If the first word on any line contains a command other than the four listed above, an error message should be displayed and that line ignored.3. The create command creates a new account object with the given account number and initial balance. If an account already exists with that number an error message should be displayed and the command ignored.4. The Deposit and Withdraw commands perform the indicated operation on an existing account. If no account with that number has been…
Using the Automobile class you created Chapter 10, Programming Exercise 5A as a base, derive a FinancedAutomobile class that contains all the data of an Automobile, plus the following field: AmtFinanced - The amount financed (a double) Override the parent class ToString() method to include the child class’s additional data. Create a program named AutomobileDemo2 that contains an array of four FinancedAutomobile objects. Prompt the user for all the necessary data, and do not allow duplicate ID numbers and do not allow the amount financed to be greater than the price of the automobile. Sort all the records in ID number order and display them with a total price for all FinancedAutomobiles and a total amount financed. For example, the output should be in the following format: Summary: FinancedAutomobile 1 2017 Honda Price is $26,000.00 Amount financed $12,000.00 FinancedAutomobile 4 2019 Honda Price is $36,000.00 Amount financed $0.00 FinancedAutomobile 5 2016 Toyota Price is $30,000.00…

Modify the attached code: Create a new class called CalculatorWithMod. This class should be a sub class of the base class Calculator. This class should also have an additional method for calculating the modulo. The modulo method should only be seen at the sub class, and not the base class! Include exception handling for instances when dividing by 0 or calculating the modulo with 0. You would need to use throw, try, and catch. The modulo (or "modulus" or "mod") is the remainder after dividing one number by another.Example: 20 mod 3 equals 2Because 20/3 = 6 with a remainder of 2 Refer also to the attached sample outputs:
