Easter Sunday is the first Sunday after the first full moon of spring. To compute the date, you can use this algorithm, invented by the mathematician Carl Friedrich Gauss in 1800:
1. Let y be the year (such as 1800 or 2001).
2. Divide y by 19 and call the remainder a. Ignore the quotient.
3. Divide y by 100 to get a quotient b and a remainder c.
4. Divide b by 4 to get a quotient d and a remainder e.
5. Divide 8 * b 13 by 25 to get a quotient g. Ignore the remainder.
6. Divide 19 * a b - d - g 15 by 30 to get a remainder h. Ignore the quotient.
7. Divide c by 4 to get a quotient j and a remainder k.
8. Divide a 11 * h by 319 to get a quotient m. Ignore the remainder.
9. Divide 2 * e 2 * j - k - h m 32 by 7 to get a remainder r. Ignore the quotient.
10. Divide h - m r 90 by 25 to get a quotient n. Ignore the remainder.
11. Divide h - m r n 19 by 32 to get a remainder p. Ignore the quotient.
Then Easter falls on day p of month n. For example, if y is 2001:
a = 6 h = 18 n = 4
b = 20, c = 1 j = 0, k = 1 p = 15
d = 5, e = 0 m = 0
g = 6 r = 6
Therefore, in 2001, Easter Sunday fell on April 15. Write a program that prompts the user for a year and prints out the month and day of Easter Sunday.

System.out.print("Year: ");

int y = input.nextInt();

int a = y%19;

System.out.println("a = "+a);

int b = y / 100;

System.out.println("b = "+b);

int c = y%100;

System.out.println("c = "+c);

int d = b / 4;

System.out.println("d = "+d);

int e = b%4;

System.out.println("e = "+e);

int g = (8 * b + 13)/25;

System.out.println("g = "+g);

int h = (19 * a + b - d - g + 15)%30;

System.out.println("h = "+h);

int j = c/4;

System.out.println("j = "+j);

int k = c%4;

System.out.println("k = "+k);

int m = (a + 11 * h)/319;

System.out.println("m = "+m);

int r = (2 * e + 2 * j - k - h + m + 32)%7;

System.out.println("r = "+r);

int n = (h - m + r + 90)/25;

System.out.println("n = "+n);

int p = (h - m + r + n + 19)%32;

System.out.println("p = "+p);

}

A program is written to compute the sum of the integers from 1 to 10. The programmer, well trained in reusability and maintainability, writes the program so that it computes the sum of the numbers from k to n. However, a team of security specialists scrutinizes the code. The team certifies that this program properly sets k to 1 and n to 10; therefore, the program is certified as being properly restricted in that it always operates on precisely the range 1 to 10.

Required:
List different ways that this program can be sabotaged so that during execution it computes a different sum, such as 3 to 20.

Answers

Answer:

See explanation

Explanation:

An instance of such program written in python is

isum = 0

for i in range(1,11):

isum = isum + i

print(sum)

One of the ways the program can give a wrong result is when someone alters the program source program before it's complied and executed.

Take for instance.

Changing

isum = 0 to isum = 4

will alter the result by additional 4

Another way is if an outside program or process alters the program execution.

You have a large text file of people. Each person is represented by one line in the text file. The line starts with their ID number and after that, has the person's name. The lines are sorted by ID number in ascending order. There are n lines in this file. You write a search function that returns the name of a person whose ID number is given The simplest way to do that would be to program a loop that goes through each line and compares the ID number in the line against the given ID number. If there is a match, then it returns the name in that line. This is very inefficient, because the worst-case scenario is that this program needs to go through almost everyone the person we are looking for could be last. using the fact that he tli s sored wil greany speed up the processbus to use a birarysearch alkrhm We go to the middle line of the file first and compare the ID found there (P) to the given ID (Q). (f the number of lines is even, we go above or below the arithmetic middle.) if P=Q then our algorithm terminates . we have found the person we are looking for. If P is less than Q, that means that the person we are looking for is in the second half of the file. We now repeat our algorithm on the second half of the file. If P is greater than Q, that means that the person we are looking for is in the first half of the file. We now repeat our algorithm on the first half of the file.

Required:
Of what order is the worst-case number of comparison operations that needed for this algorithm to terminate?

Write a short quiz program which asks three true/false questions and stores the user's answers as booleans. At the end the program it should print the user's answers with the correct answers.

Note: you should use the same quiz questions and correct answers as the sample run below.

Sample run:

Java is a programming language, true or false?
true
Only numbers can be stored by variables in Java, true or false?
true
There are only 2 possible values which can be held by a boolean variable, true or false?
false
Question 1 - Your answer: true. Correct answer: true
Question 2 - Your answer: true. Correct answer: false
Question 3 - Your answer: false. Correct

The concept of boolean variables is that; variables declared as boolean type can only take any of two values. The variable can either be true or false. Such variable cannot take any other value apart from these two.

The short quiz program is as follows.

Please note that comments are used to explain difficult lines.

import java.util.*;

public class shortQuiz{

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

//This declares the variables that represent correct answers as boolean data type; the variables are also initialized

boolean q1 = true, q2 = false, q3 = true;

//This declares the response to each question as boolean data type

boolean q1response, q2response, q3response;

//This prints the first question

System.out.print("Java is a programming language, true or false? ");

//This gets input for the first response

q1response = input.nextBoolean();

//This prints the second question

System.out.print("Only numbers can be stored by variables in Java, true or false? ");

//This gets input for the second response

q2response = input.nextBoolean();

//This prints the third question

System.out.print("There are only 2 possible values which can be held by a boolean variable, true or false? ");

//This gets input for the third response

q3response = input.nextBoolean();

//This prints your first response, alongside the correct answer to the first question

System.out.println("Question 1 - Your answer: "+q1response+". Correct answer: "+q1);

//This prints your second response, alongside the correct answer to the second question

System.out.println("Question 2 - Your answer: "+q2response+". Correct answer: "+q2);

//This prints your third response, alongside the correct answer to the third question

System.out.println("Question 3 - Your answer: "+q3response+". Correct answer: "+q3);

//The program ends here

}

See attached image for program sample run.

The above program initializes the correct answers using boolean variables. The correct answers are then printed, after the user answers the three questions.

As a twist on the Hello World exercise, you are going to be the end user of the Hello class. This class is designed to greet the user in a variety of world languages. For this task, complete the following:
Use the Scanner class to ask the user for their name.
Create a Hello object by passing the name to the constructor.
Call at least 3 methods from the Hello class to print the greeting in 3 different languages.
Remember to write your code in the HelloTester class, but make sure you take a look at the Hello class so that you know the names of the methods you need to use.

Answers

Answer:

Here is the Hello class:

public class Hello { //class name

private String name; //to store the name

public Hello (String names) //parameterized constructor

{ name = names; }

public void English() { //method to greet user in english

System.out.print("Hello "); //displays Hello on output screen

System.out.print(name); //displays user name

System.out.println("!"); } //displays exclamation mark symbol

public void Spanish(){ //method to greet user in spanish

System.out.print("Hola "); //displays Hello on output screen

System.out.print(name); //displays user name

System.out.println("!"); } //displays exclamation mark symbol

public void French() { //method to greet user in french

System.out.print("Bonjour "); //displays Hello on output screen

System.out.print(name); //displays user name

System.out.println("!"); } } //displays exclamation mark symbol

Explanation:

Here is the HelloTester class:

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

public class HelloTester { //class name

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

String name; //to store the name of user

Scanner input = new Scanner(System.in); //creates Scanner class object

System.out.println("Enter name?" ); //prompts user to enter name

name = input.nextLine(); //scans and reads the name from user

Hello hello = new Hello(name); //creates Hello class object and calls constructor by passing name

hello.English(); //calls English method using object hello to greet in english

hello.Spanish(); //calls Spanish method using object hello to greet in spanish

hello.French(); } } //calls French method using object hello to greet in french

The output of the program is:

Enter name? user Hello user! Hola user! Bonjour user!

The screenshot of the program along with its output is attached.
