Give an example of an if/else statment and a case statment that are equivalent. Your example should contain at least three choic

zimovet [89]

Answer:

The if - else and equivalent switch case statements in c++ language are given below.

if ( ch == 1 )

cout << " sum is " << x + y << endl;

else if ( ch == 2 )

cout << " difference is " << x - y << endl;

else if ( ch == 3 )

{

cout << " Quitting " << endl;

exit;

}

switch( ch )

{

case 1 : cout << " Sum is " << x + y << endl;

break;

case 2 : cout << " Difference is " << x - y << endl;

break;

case 3 : cout << " Quitting " << endl;

break;

}

Explanation:

The above statements use three variables which are declared and initialized as shown.

int x = 10;

int y = 25;

int ch;

The above statements execute for of addition, subtraction or to quit the program.

cout << " 1. Addition " << endl;

cout << " 2. Subtraction. " << endl;

cout << " 3. Quit " << endl;

cout << " Enter your choice " << endl;

The variable ch holds the numerical option entered by the user.

cin >> ch;

For if - else statements, the if statement is executed based on the value of variable ch entered by the user. After execution, the compiler goes out of the statements automatically.

Following the if – else, if any statement is present, it will be executed.

For switch case, every case ends with break keyword. After the required case is executed based on the value of variable ch entered by the user, the break statement is executed which causes the switch case to terminate the control goes out of the statements.

Following the switch case, if any statement is present, it will be executed.

wolverine [178]

Answer:

See explaination

Explanation:

The program code

import java.util.ArrayList;

public class Main

{

public static void main(String[] args)

{

ArrayList<AirlineTicket> tickets = new ArrayList<AirlineTicket>();

//This creates a randomized list of passengers

addPassengers(tickets);

for(AirlineTicket elem: tickets)

{

System.out.println(elem);

}

//This creates a TicketOrganizer object

TicketOrganizer ticketOrganizer = new TicketOrganizer(tickets);

//These are the methods of the ticketOrganizer in action

System.out.println("\nPassengers Ordered by Boarding Group:");

ticketOrganizer.printPassengersByBoardingGroup();

System.out.println("\nPassengers in line who can board together:");

ticketOrganizer.canBoardTogether();

}

//Do not touch this method! It is adding random passengers to the AirlineTicket array

public static void addPassengers(ArrayList<AirlineTicket> tickets)

{

String[] seats = {"A","B","C","D","E","F"};

for(int index = 0; index< 15; index++)

{

int random = (int)(Math.random() * 5);

AirlineTicket ticket = new AirlineTicket("Passenger " + (index+1), seats[random], ((int)(Math.random()*5)+1), ((int)(Math.random()*8)+1));

tickets.add(ticket);

}

class TicketOrganizer

{

private ArrayList<AirlineTicket> tickets ;

//constructor with parameter as an arraylist of AirlineTicket

public TicketOrganizer(ArrayList<AirlineTicket> tickets)

{

this.tickets = tickets;

}

//methhods to return the arraylist of airlines

public ArrayList<AirlineTicket> getTickets()

{ //re-organize the ticket first

ArrayList<AirlineTicket> tickets_organized = new ArrayList<AirlineTicket>();

for(int i=1; i<=5; i++)

{

for(AirlineTicket ticket: tickets)

{

if(ticket.getBoardingGroup() == i)

{

tickets_organized.add(ticket);

}

return tickets_organized;

}

//print the tickets based on boardingGroup

public void printPassengersByBoardingGroup()

{

int count = 0;

for(int i=1; i<=5; i++)

{

System.out.println("Boarding Group " + i + ":");

for(AirlineTicket ticket : tickets)

{

if(ticket.getBoardingGroup() == i)

{

System.out.println("Passenger " + ticket.getName());

}
