Question

Lodging in Europe

Q1. Write a program to make suggestions on lodging in Europe.

• If a user wants to spend $30 or less on lodging per night, suggest camping.
• If a user wants to spend $45 or less but more than $30 per night, suggest youth hostel if the user is 30 years old or younger and adult hostel if the user is older than 30 years old.
• If a user wants to spend $100 or less but more than $45 per night, suggest hotel.
• If a user wants to spend $200 or less but more than $100 per night, suggest grant hotel.
• If a user wants to spend more than $200, suggest exclusive suites. If the country is France, also suggest rooms in palaces.

Note that to compare whether a String variable country equals "France", you cannot use country == "France". The correcr way to compare is country.equals("France").

Q2.

Days of a Month

Given the year and month number, return the number of days in the month.

• For month 1, 3, 5, 7, 8, 10, 12, return 31.
• For month 4, 6, 9, 11, return 30.
• For month 2, if it is leap year, return 29, otherwise return 28.

A year is a leap year if the year number is a multiple of 4 but not a multiple of 100. However, if a year number is a multiple of 400, the year is a leap year.

Answer 1

Since you have not mentioned the language of your preference, I am providing the code in Java.

1)

CODE

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

double spend;

System.out.println("Enter the amount you want to spend on lodging per night: ");

spend = sc.nextDouble();

if (spend <= 30) {

System.out.println("Go to camping");

} else if (spend <= 45) {

System.out.println("Enter your age: ");

int age = sc.nextInt();

if (age <= 30) {

System.out.println("Take youth hostel");

} else {

System.out.println("Take adult hostel");

}

} else if (spend <= 100) {

System.out.println("Hotel");

} else if (spend <= 200) {

System.out.println("Grand hotel");

} else {

System.out.println("Enter the country: ");

String country = sc.nextLine();

if ("France".equalsIgnoreCase(country)) {

System.out.println("Go to palaces");

} else {

System.out.println("Take exclusive suites");

}

}

}

}

2)

CODE

import java.util.Scanner;

public class Main {

public static boolean isLeapYear(int year)

{

// If a year is multiple of 400,

// then it is a leap year

if (year % 400 == 0)

return true;

  

// Else If a year is muliplt of 100,

// then it is not a leap year

if (year % 100 == 0)

return false;

  

// Else If a year is muliplt of 4,

// then it is a leap year

if (year % 4 == 0)

return true;

return false;

}

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

System.out.println("Enter the month: ");

int month = sc.nextInt();

System.out.println("Enter the year: ");

int year = sc.nextInt();

if (month == 1 || month == 3 || month == 5 || month == 7 || month == 8 || month == 10 || month == 12) {

System.out.println("Number of days = 31");

} else if (month == 4 || month == 6 || month == 9 || month == 11) {

System.out.println("Number of days = 30");

} else {

if (isLeapYear(year)) {

System.out.println("Number of days = 29");

} else {

System.out.println("Number of days = 28");

}

}

}
