Code example 2-1 import java.util.Scanner; public class InvoiceApp { public static void main(String[] args) { Scanner sc = new Scanner(System.in); String choice = “y”; While (choice.equals(“y”)) { System.out.print("Enter subtotal: "); double subtotal = sc.nextDouble(); double salesTax = subtotal * .0875; double invoiceTotal = subtotal + salesTax; String message = “Subtotal = ” + subtotal + “\n” + “ Sales tax = ” + salesTax + “\n” + “Invoice total = ” + invoiceTotal + “\n\n” System.out.println(message); System.out.print(“Continue? Enter y or n: ”); Choice = sc.next(); } } } (Refer to code example 2-1.) If the user enters 100 the first time the while loop is executed, what will the program display at the console? a. Subtotal: 100.0 Sales tax: 8.75 Invoice total: 108.75 b. Subtotal = 100.0 Sales tax = 8.75 Invoice total = 108.75 c. Subtotal = 100.0 Sales tax = 8.75Invoice total = 108.75 d. Subtotal = 100.0 Sales tax = 8.75Invoice total = 108.75

Statement that increases numPeople by 5. Ex: If numPeople is initially 10, the output is: There are 15 people.

Java

program that takes a first name as the input, and outputs a welcome message to that name. Ex: If the input is: Chrystal the output is: Hey Chrystal! Welcome to zyBooks!

Here is a statement: class temporary { public: void set(string, double, double); void print(); double manipulate(); void get(string&, double&, double&); void setDescription(string); void setFirst(double); void setSecond(double); string getDescription() const; double getFirst()const; double getSecond()const;  temporary(string = "", double = 0.0, double = 0.0);  private: string description; double first; double second; };  How do I write the definition of the member function set so that the instance variables are set according to the parameters?

using System; class Program { publicstaticvoid Main(string[] args) { int number = 1; while (number <= 88) { Console.WriteLine(number); number = number + 2; } int[] randNo = newint[88]; Random r = new Random(); int i=0; while (number <= 88) { randNo[i] = number; number+=1; i+=1; } for (i = 0; i < 3; i++) { Console.WriteLine("Random Numbers between 1 and 88 are " + randNo[r.Next(1, 88)]); } } }     this code counts from 1-88 in odds and then selects three different random numbers. it keeps choosing 0 as a random number everytime. how can that be fixed?

class temporary { public: void set(string, double, double); void print(); double manipulate(); void get(string&, double&, double&); void setDescription(string); void setFirst(double); void setSecond(double); string getDescription() const; double getFirst()const; double getSecond()const;  temporary(string = "", double = 0.0, double = 0.0);  private: string description; double first; double second; };  I need help writing the definition of the member function set so the instance varialbes are set according to the parameters. I also need help in writing the definition of the member function manipulation that returns a decimal with: the value of the description as "rectangle", returns first * second; if the value of description is "circle", it returns the area of the circle with radius first; if the value of the description is "cylinder", it returns the volume of the cylinder with radius first and height second; otherwise, it returns with the value -1.

using System; class main { publicstaticvoid Main(string[] args) { int number = 1; while (number <= 88) { int i; Random r = new Random(); int[] randNo=newint[3]; for(i=0;i<3;i++) { randNo[i]= r.Next(1,88); Console.WriteLine("Random Number between 1 and 88 is "+randNo[i]); } } } }   This code is supposed to count from 1-88 and then select three random numbers from the list but instead it generates an infinite loop of random numers between 1-88. how can it be fixed?
