Could i get a walk trough how to solve these questions. Note that   is where the answer is meant to go.

Question 1

Say, instead of a separate variable (nItems), the number of items currently in the list are stored at index 0 in the array data, the actual values being stored starting at index 1. Complete the constructor that instantiates a list that can hold n values (excluding the item that holds the number of items currently in the list). That is, one should be able to add n values to the list before the need to grow it.

public class PackedArrayList {
public int[] data;

public PackedArrayList(int n) {
data = new int[  ];
data[0] =  ;
}
}

Question 2

Complete the body of method addEnsureCapacity in the following code:
public class MyArrayList {
public int[] data;
public int nItems;
public MyArrayList(int n) {
data = new int[n];
nItems = 0;
}
public void grow() {
//assume it increases capacity by 10
}
public boolean isFull() {
return (nItems == data.length);
}
public void addBasic(int val) {
data[nItems] = val;
nItems++;
}
public void addEnsureCapacity(int val) {
if(  == false) {
 ;
}
else {
 ;
addBasic(val);
}
}
}

In C++ Please

Problem   1:   How   to   calculate   a   home's   value  


Housing economists have long used a home price/rent ratio as one way to gauge whether or not home prices are inflated or undervalued.


A housing P/E


The use of a price/rent ratio is analogous to employing a price/earnings ratio for stocks. When a stock price is high, and its earnings per share relatively low, the P/E is high. A high P/E often indicates that the stock is too expensive, and the share price is headed for a drop.
What someone is willing to pay to rent a place is that home's "earnings." And, just as in the stock market, a high home price related to the rental earnings mean homes values will probably drop.
For a specific look at how a home's P/E is determined, let's consider a home that is listed for either rent or sale in suburban Chicago.
The home has been rented for the past three years for $1,600 per month; so that is $19,200 per year. It is currently listed for sale at $400,000. Dividing the price by the total annual rent of $19,200 gives a "housing P/E" of 20.83. According to Moody's Economy.com, the long-run average housing P/E is 16, so a P/E of 20.83 suggests that this home may be somewhat overpriced.


For this programming project you will read in a list of housing prices and how much each house is rented for that are found in the attached HousingPrices.txt file. The file looks like this:


713047 1246
1605787 1979
1174719 1879
1018239 1700


Where the first value on each line is the price of the home, and the second number on each line is the price that this home currently rents for per month.
Read these numbers in from the file into 2 separate arrays of size 100, since there are 100 home prices/rents in the file. Do this part in your main method.   
Then use a for-loop to loop through the arrays and for each pair of values send them into a method that you will write called "getHousingPE". Your method will have two parameters; the price of the home and the current monthly rental rate of the home. Your method will calculate and then return the homes “housing P/E”.   
Check each homes returned P/E value and if the P/E value is greater than 16 you should write to the output “House # is somewhat overpriced”; where # is the number of the house in the file (1100). If the P/E is greater than 19 then you should write to the output “House # is way overpriced”. If the P/E is less than 12 then you should write to the output "“House # might be a good deal”. And if the P/E is less than 9 then you should write “Buy House #, it is a deal”. If the P/E is between 12-16 then output "House # is average".

Problem   2:   Determining   Left   or   Right    

For   this   programming   project   you   are   to   read   in   a   list   of   street   addresses   and   determine   how   many   of   those   addresses   are   on   the   right   side   of   the   street,   and   how   many   are   on   the   left.   The   street   addresses   file   is   a   text   file   that   looks   like:  
  
6 S 33rd St

6 Greenleaf Ave

618 W Yakima Ave

74 S Westgate St

3273 State St
  

You   can   determine   if   an   address   is   either   on   the   left   or   right   side   of   the   street   by   looking   at   the   number   of   the   address;   all   even   numbers   are   on   the   right   side   of   the   street,   and   all   odd   numbers   are   on   the   left   side   of   the   street.  
  
You   will   read   your   data   into   2   arrays;   an   integer   array   to   hold   the   street   number,   and   a   String   array   to   hold   the   rest   of   the   address.       These   will   be   parallel   arrays,   meaning   the   street   number   and   street   address   of   each   index   are   related   to   each   other.  
  
Remember   to   draw   a   picture   so   that   you   can   visualize   this.  
  
You   will   need   to   write   a   method   that   will   determine   if   each   house   is   on   the   left   or   right   side   of   the   street.  
  
You   will   call   this   method   for   every   street   address,   and   then   keep   a   count   of   how   many   houses   are   on   the   left   and   right   sides   of   the   street.  
  
The   output   should   be   the   street   number   and   address   and   then   whether   the   house   is   on   the   left   or   right   side   of   the   street:  
  
Address Left/Right

6649 N Blue Gum St left

4 B Blue Ridge Blvd right

8 W Cerritos Ave #54 right

639 Main St left


  

The   number   of   houses   on   the   left   and   right   sides   of   the   street   should   also   be   output.

Write a C Unix shell script called showperm that accepts two command line parameters. The first parameter should be an option flag, either r, w or x. The second parameter should be a file name. The script should indicate if the specified file access mode is turned on for the specified file, but it should display an error message if the file is not found. For example, if the user enters: showperm r thisfile the script should display “readable” or “not readable” depending on the current status of thisfile.

You are assigned to implement the following baggage-check-in system at the airport.

The system keeps track of data for the following information: passenger, bags, and tickets.

The program must maintain passenger details like name, address, phone number, and the number of bags. Each passenger can have multiple bags and each bag has length, width, height, and weight. The passenger also has a ticket. The tickets are of two types, either a first-class ticket or an economy-ticket. The maximum weight allowed for a first-class ticket is 40 Kilos and the maximum weight allowed for an economy-ticket is 30 Kilos. The program must display all the details of the passenger, ticket, and number of bags and allowed weight. If the weight exceeds that of the respective ticket class, then the program will give appropriate message to indicate that the passenger cannot travel. Your program must throw an exception to indicate the failure.

Requirements

  • Implement the following functions:
    1. checkOverweigth() # Given the ticket number, check if the total weight of all bags exceeds limit
    2. checkPassengerClass() # Given the ticket number, the class of the ticket is given
    3. displayPassengerDetails() # Given the ticket number, display all check-in details of a passenger
  • Student is required to identify classes, related attributes, and behaviors. Students are free to add as many attributes as required. The appropriate access modifiers (private, public, or protected) must be used while implementing class relationships. Proper documentation of code is mandatory.
  • Student must also test the code, by creating at-least three objects. All classes must have a display function, and the program must have functionality to print current state of the objects.

Black Jack

Create a program that uses methods and allows the user to play the game of blackjack against the computer dealer. Rules of Blackjack to remember include:

1. You need one 52 card deck of cards with cards from  2-Ace (4 cards of each number).

2. Jacks, Queens and Kings count as 10 points.

3. An Ace can be used as either 1 or 11 depending on what the user decides during the hand.

4. Draw randomly two cards for the "dealer" and display one of them while keeping the other hidden. Also, randomly draw two cards for the player and display them in view.

5. Allow the user to hit (randomly draw a card) as many times as they wish. If the player "busts" or gets over 21, the dealer automatically wins the players wager.

6. After the user "stands" or is satisfied with his total, the dealer must take a card if his total is 16 or below, and cannot take a card if his total is 17 or above.

7. If the dealer "busts" or goes over 21, the player wins back his wager plus his wager again. (Example - if a player bets $3 he gets back his original $3 plus an additional $3).

8. If neither the dealer or the player "busts" or goes over 21, then the highest total wins. Ties go to the dealer.

9. Note - the player should start with $20 in the bank and cannot wager more than he currently has in the bank.  

10.  Note - before each round the user can bet in whole dollars how much to wager or how much of the total in the bank to risk.

11. Allow the user to quit at any time. Of course, the user must quit if he/she runs out of money.

12. Remember, somehow ensure that the same card (example - 6 of spades) cannot be drawn twice in a single hand.
