Consider the following class declaration: public class Square { private double sideLength; public double getArea() { return sideLength * sideLength; } public double getSideLength() { return sideLength; } } Assuming that a no-arg constructor already exists, write an overloaded constructor for this class. It should accept an argument that is copied into the sideLength field. The parameter’s name is s.
Answer:
Here is the constructor:
public Square(double s) { //constructor name is same as class name
sideLength = s; } //s copied into sideLength field
Explanation:
The above constructor is a parameterized constructor which takes a double type variable s as argument. The name of constructor is same as the name of class.This constructor requires one parameters. This means that all declarations of Square objects must pass one argument to the Square() constructor as constructor Square() is called based on the number and types of the arguments passed and the argument passed should be one and of type double.
Here is where the constructor fits:
public class Square {
private double sideLength;
public Square(double s) {
sideLength = s; }
public double getArea() {
return sideLength * sideLength;}
public double getSideLength() {
return sideLength; } }
To follow the Principle of Least Privilege, Set-UID programs often permanently relinquish their root privileges if such privileges are not needed anymore. Moreover, sometimes, the program needs to hand over its control to the user; in this case, root privileges must be revoked. The setuid() system call can be used to revoke the privileges. According to the manual, "setuid() sets the effective user ID of the calling process. If the effective UID of the caller is root, the real UID and saved set-user-ID are also set". Therefore, if a Set-UID program with effective UID 0 calls setuid(n), the process will become a normal process, with all its UIDs being set to n. When revoking the privilege, one of the common mistakes is capability leaking. The process may have gained some privileged capabilities when it was still privileged; when the privileged is downgraded, if the program does not clean up those capabilities, they may still be accessible by the non-privileged process. In other words, although the effective user ID of the process becomes non-privileged, the process is still privileged because it possesses privileged capabilities. Compile the following program, change its owner to root, and make it a Set-UID program. Run the program as a normal user, and describe what you have observed. Will the file /etc/zzz be modified? Please explain your observation.

This program will calculate the rise in ocean levels over 5, 10, and 50 years, Part of the program has been written for you. The part that has been written will read in a rise in ocean levels (per year) in millimeters. This value is read into a variable of type double named risingLevel. You will be completing the program as follows Output the value in risingLevel. This should be the first line of output. The output should be as follows (assume risingLevel has a value of 2.1) Level: 2.1 The number of millimeters higher than the current level that the ocean's level will be in 5 years (assuming the ocean is rising at the rate of risingLevel per year). This is your second line of output. The output will be as follows Years: 5, Rise: 10.5 The number of millimeters higher than the current level that the ocean's level will be in 10 years (assuming the ocean is rising at the rate of risingLevel per year). This is your third line of output. The output will be as follows (for a risingLevel" of 2.1 Years: 10, Rise: 21 The number of millimeters higher than the current level that the ocean's level will be in 50 years (assuming the ocean is rising at the rate of risingLevel per year). This is your final line of output.The output will be as follows (for a risingLevel" of 2.1) Years: 50, Rise: 105 For each of the above you need to output the number of years and the total rise in ocean levels for those years. This is all based on the value in risingLevel For example: ArisingLevel of 2.1 for 5 years would have the following output: Level: 2.1 Years: 5, Rise: 10.5 Years: Years: 50, Rise: 105 10, Rise: 21 Your output must have the same syntax and spacing as above
Answer:
Here is the C++ program:
#include <iostream> //to use input output functions
using namespace std; //to identify objects cin cout
int main(){ //start of main method
double risingLevel; //declares a double type variable to hold rising level
cin>>risingLevel; //reads the value of risingLevel from user
cout<<"Level: "<<risingLevel<<endl; //displays the rising level
cout << "Years: 5, Rise: " << risingLevel * 5<<endl; //displays the rise in ocean level over 5 years
cout << "Years: 10, Rise: " << risingLevel * 10<<endl; //displays the rise in ocean level over 10 years
cout << "Years: 50, Rise: " << risingLevel * 50<<endl; //displays the rise in ocean level over 50 years
}
Explanation:
The program works as follows:
Lets say the user enters rising level 2.1 then,
risingLevel = 2.1
Now the first print (cout) statement :
cout<<"Level: "<<risingLevel<<endl; prints the value of risingLevel on output screen. So this statement displays:
Level: 2.1
Next, the program control moves to the statement:
cout << "Years: 5, Rise: " << risingLevel * 5<<endl;
which computes the rise in ocean levels over 5 years by formula:
risingLevel * 5 = 2.1 * 5 = 10.5
It then displays the computed value on output screen. So this statement displays:
Years: 5, Rise: 10.5 Next, the program control moves to the statement:
cout << "Years: 10, Rise: " << risingLevel * 10<<endl;
which computes the rise in ocean levels over 10 years by formula:
risingLevel * 10 = 2.1 * 10 = 21
It then displays the computed value on output screen. So this statement displays:
Years: 10, Rise: 21
Next, the program control moves to the statement:
cout << "Years: 50, Rise: " << risingLevel * 50<<endl;
which computes the rise in ocean levels over 50 years by formula:
risingLevel * 50 = 2.1 * 50 = 105
It then displays the computed value on output screen. So this statement displays:
Years: 50, Rise: 105 Hence the output of the entire program is:
Level: 2.1 Years: 5, Rise: 10.5 Years: 10, Rise: 21 Years: 50, Rise: 105
The screenshot of the program and its output is attached.

Explanation:
The "Print Preview" gives a person the idea on how his/her document will look like once it is printed out. Having an overview of the document will let you know whether you need to do some adjustments or edit some things before you actually print it.
There's a shortcut for this when it comes to the "Microsoft Word." All you have to do is to press ctrl + F2. Nevertheless, more modern computers don't need the print preview anymore since you can see the whole document on the actual print page.

Write a Java program that generates a random number between 0 and 50. Then, the program prompts for guesses until the user is correct, or has made 10 wrong guesses. After each guess, the program indicates whether the guess was too high, too low, or correct. Once the round has ended, either by a correct guess or by using up the 10 guesses, the program displays the current status. Enter an integer number ( 0 to exit): 3241 3241 has 4 digits. Sum of digits of 3241 is 10. Enter an integer number ( 0 to exit): 264 264 has 3 digits. Sum of digits of 264 is 12. Enter an integer number ( 0 to exit): -12 -12 has 2 digits. Sum of digits of -12 is -3. Enter an integer number ( 0 to exit): 0 End. Enter a positive integer between 0 and 9: -3 Invalid input number. Enter a positive integer between 0 and 9: 15 Invalid input number. Enter a positive integer between 0 and 9: 5 0 !
Answer:
Here is the JAVA program:
import java.util.Scanner; //to accept input from user
public class Main { //class name
public static void GuessTheNumber() { //method to guess the number
Scanner input = new Scanner(System.in); //creates Scanner object to accept input from user
int number = (int)(50 * Math.random()) ; //generates random number from 0 to 50
int trials = 10; //allows 10 trials to user to guess the number
int i, userGuess; //stores user guess
System.out.println("Guess a number between 0 to 50"); //prompts user to guess a number between 0 to 50
for (i = 0; i <trials; i++) { //allows user to keep guessing in 10 trials
System.out.println("Enter your guess: "); //prompts user to enter a number as a guess
userGuess = input.nextInt(); //reads users entered number(guess)
if (number == userGuess) { //if users guess is correct
System.out.println("Congratulations! The guess is correct!"); //displays congratulatory message
break; } //the loop breaks after correct guess is made
else if (number>userGuess) { //if user guess is less than correct number
System.out.println("Too low"); }
else if (number<userGuess) { //if user guess is greater than correct number
System.out.println("Too high"); } }
if (i == trials) { //if user has made 10 wrong guesses
System.out.println("You exceeded 10 trials!");
System.out.println("The correct number was " + number); } } //displays the correct number if user made 10 wrong guesses
public static void main(String arg[]) { //start of main method
GuessTheNumber(); } } //calls method to start the guessing game
Explanation:
The program prompts the user to enter a guess and it uses random() method to generate randoms numbers from 0 to 50. The loop keeps iterating and prompting the user to enter a guess until the limit of number of trials exceeds. The trials are set to 10 so the user can guess a number in 10 tries. If the user guesses a number that is higher than the correct guess then the program indicates that the guess is too high by displaying a message "too high" and if user guesses a number that is lower than the correct guess then the program indicates that the guess is too low by displaying a message "too low". If user makes 10 wrong guess then the program displays the correct guess and ends. The screenshot of the output is attached.

Walk.Eat,ListenSpeakDrinkWrite a program that prompts the user to enter: The cost of renting one room The number of rooms booked The number of days the rooms are booked The sales tax (as a percent). The program outputs: The cost of renting one room The discount on each room as a percent The number of rooms booked The number of days the rooms are booked The total cost of the rooms The sales tax The total billing amount. Your program must use appropriate named constants to store special values such as various discounts.
Answer:
Written in Python
cost = float(input("Cost of one room: "))
numrooms = int(input("Number of rooms: "))
days = int(input("Number of days: "))
salestax = float(input("Sales tax (%): "))
print("Cost of one room: "+str(cost))
print("Discount: 0%")
print("Number of rooms: "+str(numrooms))
print("Number of days: "+str(days))
totalcost = numrooms * cost
print("Total cost: "+str(totalcost))
salestax = salestax * totalcost/100
print("Sales tax: "+str(salestax))
print("Total Billing: "+str(salestax + totalcost))
Explanation:
The next four lines prompts user for inputs as stated in the question
cost = float(input("Cost of one room: "))
numrooms = int(input("Number of rooms: "))
days = int(input("Number of days: "))
salestax = float(input("Sales tax (%): "))
The following line prints cost of a room
print("Cost of one room: "+str(cost))
The following line prints the discount on each room (No information about discount; So, we assume it is 0%)
print("Discount: 0%")
The following line prints number of rooms
print("Number of rooms: "+str(numrooms))
The following line prints number of days
print("Number of days: "+str(days))
The following line calculates total cost of rooms
totalcost = numrooms * cost
The following line prints total cost
print("Total cost: "+str(totalcost))
The following line calculates sales tax
salestax = salestax * totalcost/100
The following line prints sales tax
print("Sales tax: "+str(salestax))
The following line calculates and prints total billings
print("Total Billing: "+str(salestax + totalcost))
