4. Assume that the economy of Stockland produces four goods, rocks, socks, blocks, and clocks. Rocks and blocks are both used as weapons; they are good substitutes for each other. The quantities and prices for each of the goods in years one and two are given by the following table:

       YEAR 1                  YEAR 2      
   good quantity price good quantity price      
   rocks       200       $1   rocks   150   $4
   socks       200       $2   socks   220   $5
   blocks   200       $3   blocks   400   $2
   clocks   200       $4   clocks 300    $6

   a. What is nominal GDP in year 1?
   b. What is real GDP in year 1?
   c. What is nominal GDP in year 2?
   d. What is real GDP in year 2? (Use year 1 as the base year.)
   e. What is the percentage increase in nominal GDP? Real GDP?

• You should use the divide-and-conquer strategy and write multiple functions. • You should always use arrays for the data sequences. • You should always use const int to define the sizes of your arrays. a. Write a C++ program. The program first asks the user to enter 4 numbers to form Sequence 1. Then the program asks the user to enter 8 numbers to form Sequence 2. Finally, the program shall tell which sequence has a larger average. For example, if the user enters 3 4 5 6 for Sequence 1, and 0 1 2 3 4 5 6 7 for Sequence 2. Your program should know the average of Sequence 1 is 4.5, and the average of Sequence 2 is 3.5. Therefore, your program should conclude that Sequence 1 has a larger average.

PROGRAM SIMULATION.  Understand the given JAVA program and write the output.  

1.     public class Places

       {

           public static void main(String args[])

           {

                  String place[]=new String[4];          

place[0]="Salmaniya";

place[1]="Salmabad";

place[2]="Isa Town";

place[3] = “Manama”

        System.out.println(place[3]);

        System.out.println(place[1].toLowerCase());

        System.out.println(place[2].substring(4,6);

        System.out.println(place[3].charAt(4));

        System.out.println(place[1].equals(place[2]));

           }

}

Programming Problem

Design a program in java that can perform three different arithmetic operations based on the user’s input.

The three operations are

1. Summation of integers from 1 to m

2. Factorial of a given number n (n!)

3. Finding the leftmost digit of a given integer (note: you have to use int)

This program should prompt the user a menu including four options, ask the user for one option, and perform the corresponding computation. This process will repeat until the user chooses “Quit”.

Please use this menu in your program: (use a switch statement)

Please choose one option from the following menu:

1) Calculate the sum of integers from 1 to m

2) Calculate the factorial of a given number

3) Display the leftmost digit of a given number

4) Quit

Sample Output

Below is an example of what your output should roughly look like when this lab is completed. Text in RED represents user input.

Please choose one option from the following menu:

1) Calculate the sum of integers from 1 to m

2) Calculate the factorial of a given number

3) Display the leftmost digit of a given number

4) Quit

1

Enter a number:

4

The sum of 1 to 4 is 10

Please choose one option from the following menu:

1) Calculate the sum of integers from 1 to m

2) Calculate the factorial of a given number

3) Display the leftmost digit of a given number

4) Quit

2

Enter a number: 5

The factorial of 5 is 120

Please choose one option from the following menu:

1) Calculate the sum of integers from 1 to m

2) Calculate the factorial of a given number

3) Display the leftmost digit of a given number

4) Quit

3

Enter a number:

987654321

The leftmost digit of 987654321 is 9

Please choose one option from the following menu:

1) Calculate the sum of integers from 1 to m

2) Calculate the factorial of a given number

3) Display the leftmost digit of a given number

4) Quit 4 Bye

PLEASE USE THE FOLLOWING FORMAT

I need it in the format of a do while loop

Due today please help!

public class Lab4 {

public static void main(String[] args) {
// Declare some variables you need
// -->

do {
// Display the menu
displayMenu();

// Ask the user for one option
// -->

switch (?????) {
// Define four cases for different options. Don't forget "break".
// -->
}
} while (?????);

}

/**
* Print the menu
*/
private static void displayMenu() {
System.out.println("Please choose one option from the following menu:");
System.out.println("1) Calculate the sum of integers from 1 to m");
System.out.println("2) Calculate the factorial of a given number");
System.out.println("3) Display the leftmost digit of a given number");
System.out.println("4) Quit");
}
}

If you can explain that would be awesome, thank you!
