When you add a zero to the right of a decimal number, it multiplies its value by 10 (For example, "15" becomes "150"). What simi

The code relevant to the problem in question:

import java.util.Scanner;

public class Test {

   public static void main(String[] args) {

       double number;

       double squareRootOfNumber;

       String userInput = null;

       Scanner scanner = new Scanner(System.in);

       System.out.println("Please enter a number: ");

       userInput = scanner.next();

       number = Double.parseDouble(userInput);

       squareRootOfNumber = Math.sqrt(number);

       if (number < 0) {

           throw new ArithmeticException("Cannot compute the square root of a negative number");

       }

       System.out.format("The square root of the entered number is %.2f %n", squareRootOfNumber);

   }

}

The program will output:

Please enter a number:

-90

Exception in thread "main" java.lang.ArithmeticException: Cannot compute the square root of a negative number at com..ans.Test.main(Test.java:18)

Explanation:

The standard Java library function java.lang.Math.sqrt does not throw an ArithmeticException for negative arguments, hence there’s no need to enclose your code in a try/catch block.

Instead, we manually trigger ArithmeticException using the throw keyword:

throw new ArithmeticException("Cannot compute the square root of a negative number");

Answer:

1. #include <iostream>

2. #include <cmath>

3.  

4. using namespace std;

5.  

6. int main()

7. {

8.     float radius;  

9.     cout << "Type the radius of the base: "; // Input a number

10.     cin >> radius; // Capture user input

11.      

12.     float height;  

13.     cout << "Type the height: "; // Enter a number and press enter

14.     cin >> height; // Get user input

15.      

16.     float volumeCylinder = 3.1416 * radius * radius * height;

17.     float cubeSide = std::pow(volumeCylinder, 1/3.);

18.     cout<<"Cube side is: "<< cubeSide;

19.      

20.     return cubeSide;

21. }

Explanation:

• Lines 1 to 5 observe two libraries
• Lines 6 to 7 declare the main function
• Lines 8 to 11 solicit the radius of the cylinder from the user
• Lines 12 to 15 request the user to input the cylinder's height
• Line 16 calculates the cylinder's volume with the formula        V=pi*(r^2)*h
• Line 17 computes the side length of a cube with a matching volume as the cylinder using side=∛(V)
• Lines 18 to 21 display and return the cube's side length

Answer:

public void printAll(){ // member function petAll()

   super.printAll(); //  invokes printAll() method from the superclass (base class) AnimalData using the super keyword

   System.out.print(", ID: " + idNum);} // displays the ID saved in the idNum field of the PetData class

Explanation:

This is the full PetData class:

public class PetData extends AnimalData { //

private int idNum;

public void setID(int petID) {

idNum = petID; }

// FIXME: Implement printAll() member method

/* Your solution goes here */

public void printAll(){

   super.printAll();

   System.out.print(", ID: " + idNum);}  }

The PetData class is a subclass that inherits from the base class AnimalData.

This class contains a private field, idNum, which is designated for storing the ID value.

It includes a method setID which takes petID as a parameter that corresponds to idNum. Essentially, this acts as a mutator to set the user ID.

Additionally, there is a printAll() method that makes use of the super keyword to call the printAll() method from the base class, AnimalData.

Using super refers to objects of the base class.

Here, the super keyword is utilized with the method name from the subclass PetData to avoid confusion, as both AnimalData and PetData have a method named printAll().

During the main() method, users will enter values for userName, UserAge, and UserID. For example, if the user inputs Fluffy as the name, 5 as the age, and 4444 as the userID. Then, calling userPet.printAll(); will execute the printAll() method from the PetData class since userPet is an instance of PetData.

When this method executes, it will call the printAll() of AnimalData class which outputs the Name and Age, while printAll() of PetData prints the ID. Consequently, the resulting output will be:

Name: Fluffy, Age: 5, ID: 4444

Answer:

Below is the Python code:

stock_prices = input().split() #this takes input and separates it into a list

for price in stock_prices: #this loops through each stock price

   print("$",price) #this outputs each stock price prefixed by a dollar sign

Explanation:

The logic behind the program is clearly outlined in the attached comments. To illustrate the program's workings, let's consider an example:

Imagine the user inputs the stock_prices values of

34.62 76.30 85.05

The input() method captures user input, while the split() method divides the input string, providing a list of strings as:

['34.62', '76.30', '85.05']

Following that, the loop statement for price in stock_prices: iterates through each item in the list, and print("$",price) displays each value from the list on the output screen with a dollar sign, as follows:

$ 34.62                                                                                                            

$ 76.30                                                                                                            

$ 85.05
