Sarah Jones Hours worked: 30.0 Rate of pay: 7.50 Salary for Sarah Jones is $225.00

Third Employee: Andrew Johnson Hours Worked: 31.5 Rate of pay: 10.75 Salary for Andrew Johnson is $338.63

The largest salary is $400.00 The smallest salary is $225.00

Given this class:

class Issue

{

public:

                string problem;

int howBad;

void setProblem(string problem);

};

And this code in main:

vector<Issue> tickets;

Issue issu;

a)

tickets.push_back(-99);

State whether this code is valid, if not, state the reason

b)

Properly implement the setProblem() method as it would be outside of the class. You MUST name the parameter problem as shown in the prototype like:

(string problem)

c)

Write code that will output the problem attribute for every element in the tickets vector. The code MUST work for no matter how many elements are contained in tickets. The output should appear as:

Problem #1 is the problem attribute in element 1.

Problem #2 is the problem attribute in element 2.

Write a java code to demonstrate the File IO. Your code should get the following information from the user.

• Get a file name fname for output • Get number of data (numbers) (N) you want to process from the user

• Get N numbers from the users through keyboard and store them in an array

• Get M (How many numbers to read from file)

• (Or)You are free to use same N for M (use N for both purposes) You have to define two methods:

1) To write the numbers from the array into the file fname

2) To read numbers from the file fname, store them in an array, and compute average of the numbers.

The method should display the numbers from the array and the average value.

Please identify each of the requirements as a functional requirement/property or non-functional requirement/property. For every non-functional property/requirement, please add a remark to explain why.

In Java, implement the Athlete, Swimmer, Runner, and AthleteRoster classes below. Each class must be in separate file. Draw an UML diagram with the inheritance relationship of the classes.

1. The Athlete class
a. All class variables of the Athlete class must be private.

b.is a class with a single constructor: Athlete(String lName, String fName, int birthYear, int birthMonth, int birthDay, char gender). All arguments of the constructor should be stored as class variables. There should only be getter methods for first and last name variables. There should be no getters or setters for birthYear, birthMonth, birthDay.

c. Getter and setter methods for the gender of the athlete. The method setGender accepts a character and store it as a class variable. Characters 'm', 'M' denotes male, 'f' or 'F' denotes male or female. Any other char will be treated as undeclared. The method getGender return either the word "male" or "female" or “undeclared”.

4. The method computeAge() takes no arguments and returns the athletes computed age (as of today's date) as a string of the form "X years, Y months and Z days". Hint: Use the LocalDate and Period classes.

   i. e.g. "21 years, 2 months and 3 days". ii. e.g. "21 years and 3 days".

   iii. e.g. "21 years and 2 months". iv. e.g. "21 years".

   v. e.g. "2 months and 3 days".

5. The method public long daysSinceBirth() takes no arguments and returns a long which is the number of days since the athlete’s date of birth to the current day. Hint: Use the LocalDate and ChronoUnit classes.

6. The toString method returns a string comprised of the results ofgetFname, getLName and computeAge. E.g.

   i. “Bunny Bugs is 19 years and 1 day old”

7. The equals method returns true if the name and date of birth of this athlete and the compared other athlete are the same, otherwise return false.

2. The Swimmer class
a. All class variables of the Swimmer class must be private.

2. inherits from the Athlete class and has a single constructor,

   Swimmer(String lName, String fName, int birthYear, int birthMonth, int birthDay, char gender, String team). There should be a class variable for team. There should be a getter method for team.

3. The Swimmer class stores swim events for the swimmer. There should be a class variable for events. A swimmer participates in one or more of these events. The addEvent method is oveloadedand either adds a single event for the swimmer public boolean addEvent(String singleEvent) or adds a group of events for the swimmer public boolean addEvent(ArrayList multiEvents). Each event is of type String. Duplicate events are not stored and return false if duplicate found.

4. There should be a getter method that returns the class variable events.

5. The overridden toString method returns a string comprised of the concatenation of the parent’s toString return plus " and is a swimmer for team: XXXXX in the following events: YYYYY; ZZZZZZ." E.g.

   i. “Missy Franklin is 24 years and 4 months old and is a swimmer for team: Colorado Stars. She participates in the following events: [100m freestyle, 100m backstroke, 50m backstroke]”

3. The Runner class
a. All class variables of the Runner class must be private.

2. inherits from the Athlete class and has a single constructor,

   Runner(String lName, String fName, int birthYear, int birthMonth, int birthDay, char gender, String country). There should be a class variable for country. There should be a getter method for country.

3. The Runner class stores race events for the runner. There should be a class variable for events. Each event is a Distance. The list of valid events is given below:
   M100, M200, M400, M3000, M5000, M10000. A runner participates inone or more of these events. The addEvent method is oveloadedand either adds a single event for the runner public boolean addEvent(String singleEvent) or adds a group of events for the runner public boolean addEvent(ArrayList multiEvents). Each event is of type String. Duplicate events are not stored and return false if duplicate found.

4. There should be a getter method that returns the class variable events.

5. The toString method returns a String in the form: " AAA BBBB is XX years, YY months and ZZ days. He is a citizen of CCCCCCC and is a DDDDDDDD who participates in these events: [MJ00, MK00, ML00]”. If she does not participate in M3000 or M5000 or M10000 then she is a sprinter. If she does not participate in M100 or M200 or M400 then she is a long-distance runner. Otherwise she is a super athlete. E.g.

   i. “Bunny Bugs is 19 years and 1 day old. His is a citizen of USA and is a long-distance runner who participates in these events: [M10000]”

4. The AthleteRoster class
a. All class variables of the AthleteRoster class must be private.

2. Does not inherits from the Athlete class. The AthleteRoster class has a single constructor, AthleteRoster(String semster, int year). There should be class variables for semester and year. There should be getter methods for semester and year.

3. The AthleteRoster class has only one method for adding Athlete to the roster, by using the boolean addAthlete(Athlete a)method. The method returns true if the athlete was added successfully, it returns false if the athlete object already exists in the roster and therefore was not added.

4. Your AthleteRoster class will have only one class level data structure, an ArrayList, for storing athlete objects.

5. The String allAthletesOrderedByLastName() method returns a string object with of all the names of the athletes (Swimmers, Runners, etc.) in ascending order of last names(a-z).

6. The String allAthletesOrderedByAge() method returns a string object with of all the names of the athletes (Swimmers, Runners, etc.) in descending order of age(100-0).

7. The String allRunnersOrderedByNumberOfEvents() method returns a string object with of all the names of the Runners only in ascending order of number of events they participate in (0-100).

Write a program in Java that reads an input text file (named: input.txt) that has several lines of text and put those line in a data structure, make all lowercase letters to uppercase and all uppercase letters to lowercase and writes the new lines to a file (named: output.txt).

The problem is below. This is for an intro to Python class, so, if possible keep it relatively simple and 'basic.'

The code in bold below is given:

def trade_action(current_stock, purchase_price, current_price, investment):
# Write your code here.
return "Hold Shares."

Instructions:

Many investment management companies are switching from manual stock trading done by humans to automatic stock trading by computers. You've been tasked to write a simple automatic stock trader function that determines whether to buy, sell, or do nothing (hold) for a particular account. It should follow the old saying "Buy low, sell high!"

This function takes 4 input parameters in this order:

1. current_shares - current number of shares of this stock in the account (int).
2. purchase_price - price (per share) paid for current stock in the account (float).
3. market_price - current market price (per share) of stock in the account (float).
4. available_funds - maximum amount the client is willing to spend on a stock purchase (float).

Any transaction (buy or sell) costs $10. This $10 must be paid out of the available_funds for a purchase, or out of the proceeds of a stock sale. Be sure to account for this fee in your profit calculations.

A purchase would be considered profitable when the current market price is lower than the purchase price, and the available funds will allow us to buy enough shares so that the difference in value will cover the $10 transaction fee. In this case the function should return the string "Buy # shares" where # is an integer representing the number of shares to purchase.

A sale would be considered profitable when the current market price is higher than the purchase price, and the value gained by selling the shares will cover the $10 transaction fee. In this case the function should return the string "Sell # shares" where # is an integer representing the number of shares to sell.

If neither a buy nor a sell would be profitable, then the function should return the string "Hold shares."

Here are some test cases that your function should satisfy:  

Rationale for test cases:

Test 1
Even though the current market price is very low (compared to the purchase price), after paying the $10 transaction fee, we would not have any funds left to buy shares; so we can only hold.

Test 2
After paying the $10 transaction fee, there are enough funds remaining to buy 11 shares. At a purchase_price vs. market_price difference of $1 per share, our 11 shares represent a value gain of $11 dollars, which is $1 more than the $10 transaction fee - so we come out $1 ahead.

Test 3
After paying the $10 transaction fee, there are enough funds remaining to buy 2 shares. At a purchase_price vs. market_price difference of $11 per share, our 2 shares represent a value gain of $22 dollars, which is $12 more than the $10 transaction fee - so we come out $12 ahead.

Test 4
Selling our 1 share for $11 will leave us with just $1 after we pay the $10 transaction fee. That is the same as what we paid for it, and we won't make any profit - so we should hold.

Test 5
With a market_price vs. purchase_price vs. difference of $2 per share, we stand to make $20 from the sale of our 10 shares. This is $10 more than the price of the transaction fee, so we will come out $10 ahead - therefore we should sell all 10 shares.

Test 6
Our 1 share is worth $11 more than we paid for it at the current market price. The $11 dollars obtained by selling that share now will still leave us with a profit of $1 after paying the $10 transaction fee. Profit is profit, so we should sell.

Things to think about when you’re designing and writing this program:

1. Look for opportunities to use variables as a way to name things, and to break larger more complex expressions down into simpler expressions.
2. Spend some time choosing your names carefully. Names should be descriptive.
3. Try to design and write your code a few lines at a time. Design and write a few lines, then run some tests to see if these lines are doing what you want them to do. If they are not, then analyze and correct them before you move on to the next few lines of code.

Need someone to rewrite this code to work in the same way:

int testScore;    //Numeric test score

        String input;     //To hold the user's input

        // Get the numeric test score.

        input = JOptionPane.showInputDialog("Enter your numeric test score and I will tell you the grade: ");

        testScore = Integer.parseInt(input);

        //Display the grade.

        if (testScore < 60)

           JOptionPane.showMessageDialog(null, "Your score of "+testScore+" is an F.");

        else if (testScore < 70)

           JOptionPane.showMessageDialog(null, "Your score of "+testScore+" is a D.");

        else if (testScore < 80)

           JOptionPane.showMessageDialog(null, "Your score of "+testScore+" is a C.");

        else if (testScore < 90)

           JOptionPane.showMessageDialog(null, "Your score of "+testScore+"e is a B.");

        else

           JOptionPane.showMessageDialog(null, "Your score of "+testScore+" is an A.");

    }

}

Need ans asap......

I was wondering if you can tell me if the following code is correct and if its not can it be fixed so it does not have any syntax errors.

Using C++ Design a class named PersonData with the following member variables:

1. lastName
2. firstName
3. address
4. city
5. state
6. zip
7. phone

and at a minimum the following member functions:

1. A class constructor - which initializes all the member variables above
2. a display() function - which ONLY displays all the person's data to the console
3. Also write the appropriate accessor/mutator functions for the member variables

Write a NewPersonData function. This is a stand-alone function that you can use in your main to generates a new PersonData object from user input (i.e. internally prompting and retrieving the values necessary to generate a person)

• prototype - PersonData NewPersonData();
• how to call - PersonData person = NewPersonData();

I need to write this program in Python. Write a program that displays a temperature conversion table for degrees Celsius and degrees Fahrenheit. The tabular format of the result should include rows for all temperatures between 70 and 270 degrees Celsius that are multiples of 10 degrees Celsius (check the sample below). Include appropriate headings on your columns. The formula for converting between degrees Celsius and degrees Fahrenheit is as follow F=(9/5C) +32
