Question

Write a program to determine, and output to the screen, the class of an earthquake, given its magnitude. A class of minor is given for those in the range of [0, 4), light if in [4, 5), moderate if in [5, 6), strong if in [6, 7), major if in [7, 8) and great if in [8, infinity). Write a program to guess a magic number m = 4, and output to a file, each of guesses that are made. A sequence of random numbers is generated, each in the range [1, 10]. If the number is equal to m, then the program terminates. Otherwise, it generates another number. Your submission should include the contents of the output file using a random number generator seed of 760.

Explanation / Answer

The language to write is not specified.
I assumed this assignment to be in Java language.
Please find the codes for both as below.

---------------------------------------------------
Prog1.java
----------
import java.util.Scanner;

public class Prog1 {

   public static void main(String[] args) {
       double magnitudeValue = 0;
      
       System.out.println("Please enter the magnitude of EarthQuake");
      
       // used to read input.
       Scanner sc = new Scanner(System.in);
       magnitudeValue = sc.nextDouble();
       sc.close();
      
       System.out.print("Earthquake was ");
      
       // Start with the largest value to compare i.e. 8 and above.
       if(magnitudeValue >= 8){
           System.out.print("Great");
       }
       else if(magnitudeValue >= 7 && magnitudeValue <8){
           System.out.print("Major");
       }
       else if(magnitudeValue >= 6 && magnitudeValue <7){
           System.out.print("Strong");
       }
       else if(magnitudeValue >= 5 && magnitudeValue < 6){
           System.out.print("Moderate");
       }
       else if(magnitudeValue >= 4 && magnitudeValue < 5){
           System.out.print("Light");
       }
       else if(magnitudeValue >= 0 && magnitudeValue < 4){
           System.out.print("Minor");
       }
   }
}

OUTPUT:
Please enter the magnitude of EarthQuake
5
Earthquake was Moderate

Prog2.java
----------
import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;
import java.util.Random;

public class Prog2 {

   public static void main(String[] args) throws IOException {
       int magicNumber = 4;
      
       // Seed is specified here as 760
       Random randomno = new Random(760);
      
       // output file name specified here.
       final String FILENAME = "output.txt";
      
       // FileWriter class to write to file.
       FileWriter fw = new FileWriter(FILENAME);
       BufferedWriter bw = new BufferedWriter(fw);
      
       while(true){
          
           // Generate random numbers between 1 and 10.
           int temp = randomno.nextInt(10 - 1) + 1;
          
           // write the value to file.
           bw.write(Integer.toString(temp));
           bw.newLine();
          
           // compare with magicNumber to end the loop.
           if (temp == magicNumber)
               break;          
       }
       bw.close();
       fw.close();
   }
}

OUTPUT:
A new file output.txt will be created in the same folder as this java file is present
having the random values.
