Create a class named Tile that represents Scrabble tiles. The instance variables should include a String named letter and an integer named value. Write a constructor that takes parameters named letter and value and initializes the instance variables. Write a method named printTile that takes a Tile object as a parameter and displays the instance variables (letter and value) in a reader-friendly format. Using a Driver class create a Tile object with the letter Z and the value 10, and then uses printTile to display the state of the object. Create getters and setters for each of the attributes.

Answers

Answer:

Here is the Tile class:

class Tile {   //class name  

// declare private data members of Tile class

  private int value;  //int type variable to hold the integer

  private String letter;     //String type variable to hold the letter

  public void setValue(int value){  //mutator method to set the integer value

       this.value = value;    }

   public void setLetter(String letter){   //mutator method to set the letter

       this.letter = letter;    }

   public int getValue()   //accessor method to access or get the value

     {return value;}  //returns the current integer value

   

   public String getLetter()   //accessor method to access or get the letter

      {return letter;}     //returns the current string value

   

   public Tile(String letter, int value){   //constructor that takes parameters named letter and value

     setValue(value);  //uses setValue method to set the value of value field

     setLetter(letter);   }  }  //uses setValue method to set the value of letter field

/* you can also use the following two statements inside constructor to initializes the variables:

Explanation:

Here is the driver class named Main:

public class Main{  //class name

public static void main(String[] args) { //start of main method  

           Tile tile = new Tile("Z", 10); //creates object of Tile class named tile and calls Tile constructor to initialize the instance variables  

       printTile(tile); } //calls printTile method by passing Tile object as a parameter

public static void printTile(Tile tile) { //method to displays the instance variables (letter and value) in a reader-friendly format

 System.out.println("The tile " + tile.getLetter() + " has the score of " + tile.getValue()); }  } //displays the string letter and integer value using getLetter() method to get the letter and getValue method to get the value

Explanation:

Write a C++ program that converts a measurement given in feet into the equivalent number of (a) yards, (b) inches, (c) centimeters, (d) meters. The program should first prompt the user to enter the number of feet to be converted. It should then read that value, calculate each of the converted lengths, and then display the converted lengths, rounded to two decimal places of accuracy. You should assume that the number of feet entered will be a floating point value. Note: All the converted lengths will also be floating point values. Conversion facts: 1 yard = 36 inches; 1 foot = 12 inches; 1 inch = 2.54 cm; 1 meter = 100 cm. Here is what output should look like from running the program (user input is shown in bold):Enter number of feet: 4= 1.33 yards= 48 inches= 121.92 cm= 1.22 metersPlease give me the pseudocode first similar to this:Display " "Read ...Let...Let...Display...Because this format of the pseudocode is required as part of the solution. Thank you!

Answers

Answer:

cout<<"Enter number of feet: ";

cin>>feet;

yard = feet * 12/36;

inch = yard * 36;

cmeter = inch * 2.54;

meter = cmeter * 100;

cout<<feet<<" feet = "<< yard<<" yard = "<<inch<<" inches = "<<cmeter<<" cm = "<<meter<<" m";

return 0;

}

Explanation:

This line declares all necessary variables

float feet, yard, inch, meter, cmeter;

The line prompts user for number of feet

cout<<"Enter number of feet: ";

This line gets user input

cin>>feet;

The next 4 lines converts feet to yard, inches, centimeter and meter

yard = feet * 12/36;

inch = yard * 36;

cmeter = inch * 2.54;

meter = cmeter * 100;

This line prints converted units

cout<<feet<<" feet = "<< yard<<" yard = "<<inch<<" inches = "<<cmeter<<" cm = "<<meter<<" m";

What is the value of the variable result after these lines of code are executed?

>>> a = 10
>>> b = 2
>>> c = 5
>>> result = a * b - a / c
The value of the variable is
.

Answers

Answer:

18

Explanation:

If you take the formula, and you substitute the values of the variables, it will be:

    10 * 2 - 10 / 5

Then if you remember the order of math operations, it will be:

    (10 * 2) - (10 / 5)

Which reduces to:

    20 - 2 = 18

The value of the variable result is 18

The code is represented as follows:

Python code:

a = 10

b = 2

c = 5

result = a * b - a / c

Code explanation;The variable a is initialise to 10The variable b is initialise to 2Lastly, the variable c is initialise to 5

Then the arithmetic operation  variable a multiplied by variable b minus  variable a divided by variable c is stored in the variable "result".

Printing the variable "result" will give you 18.

Use JavaWrite a program that will simulate a change machine found at cash registers. Input the amount due and amount paid from the keyboard.Tell the user how much change is owed and number of quarters, dimes, nickels, and pennies in change a customer would receive.Pay special attention to roundoff error. Your program should use division and modular division. No if’s or loops may be used. You may assume all change will be a positive number with no more than two decimal places. If more than $1.00 is owed, the full value should be included in the number of quarters returned. For example, $2.50 should be returned as 10 quarters.Hint: Modular division is a great way to find the remainder of a division. Think about how you can use this to calculate the change that is left over after some coins are given.Sample Run:Please Enter the Cost of the Item:4.57Please Enter the Amount Paid:5.00Change Owed: 0.43Quarters: 1Dimes: 1Nickels: 1Pennies: 3

Answers

Answer:

Here is the JAVA program:

import java.util.Scanner;  //to accept input from user

public class Main { // class name

 public static void main(String [] args) {  // start of main method

   Scanner input = new Scanner(System.in);  // creates Scanner class object to take input from user

   System.out.println("Please Enter the Cost of the Item: ");  // prompts user to enter the cost of item

   double itemCost = input.nextDouble();  //scans and reads the input value of item cost

   System.out.println("Please Enter the Amount Paid: ");  // prompts user to enter the amount paid

   double amount = input.nextDouble();  //scans and reads the value of amount from user

   int change = (int)(amount * 100 - itemCost * 100);  //compute the remaining amount i.e. change

   System.out.println("Change Owed: " + change / 100.0);  // displays the owed change

   int quarters = change / 25;  // computes the value for quarters

   change = change % 25;  // compute the quarters remaining

   int dimes = change / 10;  //  computes dimes

   change = change % 10;  //  computes dimes remaining

   int nickels = change / 5;  // computes nickels

   change = change % 5;  // compute nickels remaining

   int pennies = change;  // computes pennies

   System.out.println("Quarters: " + quarters);  // displays computed value of quarters

   System.out.println("Dimes: " + dimes);  // displays value of dimes

   System.out.println("Nickels: " + nickels);  // displays value of nickels

   System.out.println("Pennies: " + pennies);   }} //displays value of pennies

Explanation:

I will explain the program with an examples.

Suppose the user enters 4.57 as cost of the item and 5.00 as amount paid. Then the program works as follows:

Change is computed as

change = (int)(amount * 100 - itemCost * 100);

This becomes;

change = (int)(5.00 * 100 - 4.57 * 100)

            = 500 - 457

change = 43

Now the change owed is computed as:

change / 100.0 = 43/100.0 = 0.43

Hence change owed = 0.43

Next quarters are computed as:

quarters = change / 25;

This becomes:

quarters = 43/25

quarters = 1

Now the remaining is computed as:

   change = change % 25;

This becomes:

   change = 43 % 25;

  change = 18

Next the dimes are computed from remaining value of change as:

dimes = change / 10;

dimes = 18 / 10

dimes = 1

Now the remaining is computed as:

   change = change % 10;

This becomes:

   change = 18 % 10

  change = 8

Next the nickels are computed from remaining value of change as:

nickels = change / 5;

nickels = 8 / 5

nickels = 1

Now the remaining is computed as:

   change = change % 5;

This becomes:

   change = 8 % 5

  change = 3

At last the pennies are computed as:

pennies = change;

pennies = 3

So the output of the entire program is:

Change Owed: 0.43                                                                                                                Quarters: 1                                                                                                                      Dimes: 1                                                                                                                         Nickels: 1                                                                                                                       Pennies: 3

The function that will add a name to a list of baseball players in Python is main(). The correct option is b.

What is python?

Python is a popular computer programming language used to create software and websites, automate processes, and analyze data. Python is a general-purpose language, which means it may be used to make many various types of applications and isn't tailored for any particular issues.

A function is a section of code that only executes when called. You can supply parameters—data—to a function. The main() function in Python serves as the point at which any software application is executed.

Since the program only runs when it is executed directly, and not if it is imported as a module, the execution of the program can only begin when the main() function is declared in Python.

Therefore, the correct option is b, main().
