[C++]

Write an algorithm to transfer the elements from queue Q1 to queue Q2, so that the contents in Q2 will be in reverse order as they are in Q1 (e.g. if your queue Q1 has elements A, B, and C from front to rear, your queue Q2 should have C, B, and A from front to rear). Your algorithm must explicitly use an additional stack to solve the problem. Write your algorithm in pseudo code first.

Requirements:   You are to write a class called Point – this will represent a geometric point in a Cartesian plane (but x and y should be ints).   Point should have the following:

Data:  

• that hold the x-value and the y-value. They should be ints and must be private.

Constructors:

• A default constructor that will set the values to (2,-7)

• A parameterized constructor that will receive 2 ints (x then y) and set the data to what is received.

• A copy constructor that will receive a Point. If it receives null, then it should

throw new IllegalArgumentException(<”your meaningful String here”>);

If it is OK, the it should initialize the data (of the new instance being created) to be the same as the Point that was received.

Methods:

• The methods to be implemented are shown in the PointInterface.java. You can look at this file to see the requirements for the methods.

• Your Point class should be defined like this:

public class Point implements PointInterface

When your Point.java compiles, Java will expect all methods in the interface to be implemented and will give a compiler error if they are missing. The compiler error will read “class Point is not abstract and does not implement method ”.

You can actually copy the PointInterface methods definitions into your Point class so it will have the comments and the method headers.   If you do this, be sure to take out the ; in the method headers or you will get a “missing method body” syntax error when compiling…

• But a toString() method and a .equals(Object obj) method are automatically inherited from the Object class. So if you do not implement them, Java will find and use the inherited ones – and will not give a compiler error (but the inherited ones will give the wrong results). The Point class should have its own .toString and .equals methods.
• ==============================================================================
• This is the interface (called PointInterface.Java) for a Point class (which will represent a 2-dimensional Point)

• public interface PointInterface

  {

  // toString

  // returns a String representing this instance in the form (x,y)

  (WITHOUT a space after the ,)

  public String toString();

  // distanceTo

  // throws a new IllegalArgumentException(

  if null is received

  // returns the distance from this Point to the Point that was

  received

  // NOTE: there is a static method in the Math class called hypot

  can be useful for this method

  public double distanceTo(Point otherPoint);

  //equals - returns true if it is equal to what is received (as an Object)

  public boolean equals(Object obj);

  // inQuadrant

  // returns true if this Point is in the quadrant specified

  // throws a new IllegalArgumentException if the quadrant is

  out of range (not 1-4)

  public boolean inQuadrant(int quadrant);

  // translate

  // changes this Point's x and y value by the what is received (thus

  "translating" it)

  // returns nothing

  public void translate(int xMove, int yMove);

  // onXAxis

  // returns true if this Point is on the x-axis

  public boolean onXAxis();

  // onYAxis

  // returns true if this Point is to the on the y-axis

  public boolean onYAxis();

  //=============================================

  // The method definitions below are commented out and

  // do NOT have to be implemented

  // //===========================================

  // halfwayTo

  // throws a new IllegalArgumentException(

  if null is received

  // returns a new Point which is halfway to the Point that is

  received

  //public Point halfwayTo(Point another);

  // slopeTo

  // throws a new IllegalArgumentException(

  if null is received

  // returns the slope between this Point and the one that is

  received.

  // since the slope is (changeInY/changeInX), then first check to see if

  changeInX is 0

  // if so, then return Double.POSITIVE_INFINITY; (since the

  denominator is 0)

  //public double slopeTo(Point anotherPoint)

  }

You have been asked to define a tip-calculating function named calcTip that could be integrated into a larger piece of software designed to improve guest service at a restaurant. As a result, you must conform to the function specification used throughout the rest of the project's code:

double calcTip(double checkAmount, bool postTax, bool round);

This function, when called, calculates and returns a tip amount in U.S. dollars determined by the values of its two boolean parameters. Any extra comments with guidance will be very apprectiated, thank you so much!
----

tipCalc's parameters:

checkAmount:

The amount of a check in U.S. dollars with tax included.
Ex. a value of 15.00 represents $15.00 USD.

postTax:

The value of the postTax parameter determines whether the function calculates a tip before or after the tax has been added to a check amount.

A value of true means that the calculated tip will be based off the entire check amount.

A value of false indicates that tax must be removed from the check amount before a tip is calculated.

round:

The value of the round parameter determines whether or not the tip amount is rounded up before being returned. A value of true indicates that the value will be rounded up.

----

Assume that the tax rate for meals is a fixed 7.8% regardless of the geographical region in which
this software may be used. Also, in the interest of elevating the standard of what constitutes a
good tip, the tip rate is a fixed 20%.

As examples, a tip calculated for an entire $20.00 check (which includes tax) without rounding would be $4.00. A tip calculated for only the pre-tax amount of a $20.00 check without rounding would be $3.69.

Implementation

You must not make any changes to the calcTip's return type or parameters.

----

In main, you must prompt for and accept user input that will be used as arguments for a calcTip function call.

You have the freedom to structure main as you see fit, provided that I can execute your program and specify the following before a call to calcTip is made:

1.) the amount of the check after tax has been applied (e.g. I can enter $20.00 or similar)
2.) whether or not I want my tip to be calculated off the full check (i.e. including tax)
3.) whether or not I want to round up my tip to the nearest U.S. dollar

You must not prompt for this input inside calcTip().

----

Once this is done, a function call to calcTip must be made inside main; its return value
will be output.

Results

Output the following text in main after making the call to calcTip:

Your tip amount is $[TIP AMOUNT]

In order to verify program correctness, you should run the program four times under the following conditions:

1.) The user wants a 20% tip on a $15 check before tax with no rounding.
2.) The user wants a 20% tip on a $15 check after tax with no rounding.
3.) The user wants a 20% tip on a $15 check before tax with rounding.
4.) The user wants a 20% tip on a $15 check after tax with rounding.

Java Beginner

a)Create a class named Student that has fields for an ID number, number of credit hours earned, and number of points earned. (For example, many schools compute grade point averages based on a scale of 4, so a three-credit-hour class in which a student earns an A is worth 12 points.) Include methods to assign values to all fields. A Student also has a field for grade point average. Include a method to compute the grade point average field by dividing points by credit hours earned. Write methods to display the values in each Student field. Save this class as Student.java.

b)Write a class named ShowStudent that instantiates a Student object from the class you created and assign values to its fields. Compute the Student grade point average, and then display all the values associated with the Student. Save the application as ShowStudent.java.

c)Create a constructor for the Student class you created. The constructor should initialize each Student’s ID number to 9999, his or her points earned to 12, and credit hours to 3 (resulting in a grade point average of 4.0).Write a program that demonstrates that the constructor works by instantiating an object and displaying the initial values. Save the application as ShowStudent2.java.

I am using NetBeans IDE Java to code and I am seeking comment to the code as well (for better understanding).

1. Magic squares. An n x n matrix that is filled with the numbers 1, 2, 3, …, n² is a magic square if the sum of the elements in each row, in each column, and in the two diagonals is the same value.

Write a program that reads in 16 values from the keyboard, displays them in a 4 x 4 array, and tests whether they form a magic square.

Example:

              16     3       2      13

               5      10     11     8

               9       6       7      12

               4       15    14     1

You need to test two features:

1. Does each of the numbers 1, 2, …., 16 occur in the user input?
2. When the numbers are put into a square, are the sums of the rows, columns, and diagonals equal to each other?

Hint: use a two-dimentional array.

2. Implement a class Robot that simulates a robot wandering on an infinite plane. The robot is located at a point with integer coordinates and faces north, east, south, or west. Supply methods:

public void turnLeft()

public void turnRight()

public void move()

public Point getLocation()

public String getDirection()

The turnLeft and turnRight methods change the direction but not the location. The move method moves the robot by one unit in the direction it is facing. The getDirection method returns a string "N", "E", "S", or "W".
