Question

write the outline pseudocode (code is also allowed) for the following problem...

Catherine wants to simulate a lottery game. What steps would this require?

Imagine that Catherine wants a computer to simulate a lottery game. The computer will be generating two-digit numbers. Each time the computer generates a number, the user is first invited to guess what the number is. If the user guesses the exact number, the award is 10 000 EUR. If the user makes a correct guess on one of the digits, and on the right place, the award is 3 000 EUR. If the user guesses correctly that a digit was selected, but not which position it is in, the award is 100 EUR.

Examples:

Computer: 96: Computer: 47: Computer: 42:

User: 96 User: 43 User: 29

Award Award Award

10 000 EUR 3 000 EUR

100 EUR

Catherine’s algorithm and program can follow the below-mentioned steps:

Step 1: The computer generates a random two-digit number.

Step 2: The user makes a guess of what the number is and enters it through the keyboard.

Step 3: The computer compares the two numbers and evaluates whether the user wins anything.

Step 4: The computer displays the number that was generated in step 1.
Step 5: the computer displays a message of whether the user wins something, as suggested

above.

Step 6: The computer repeats the procedure from step 1 to step 5. The game is played 3 times.

Answer 1

The code is written in java (as asked pseudo code (code is also allowed))

Code :

import java.io.*;
import java.util.*;

class Game{

   public static void main(String[] args) {
      
       Scanner scan = new Scanner(System.in);

       Random random = new Random();

       for(int i=0;i<3;i++){

           int computerNumber = random.nextInt(90)+10; // for random number between 10 to 99

           System.out.println("Enter the guessing number : ");
           int guess = scan.nextInt();

           if(computerNumber == guess){

               System.out.println("The computer generated number is : " + computerNumber);
               System.out.println("The guessed number is : " + guess);
               System.out.println("Award : 10000 EUR");
           }

           else if(computerNumber/10 == guess/10 || computerNumber%10 == guess%10){

               System.out.println("The computer generated number is : " + computerNumber);
               System.out.println("The guessed number is : " + guess);
               System.out.println("Award : 3000 EUR");
           }

           else if(computerNumber/10 == guess%10 || computerNumber%10 == guess/10){

               System.out.println("The computer generated number is : " + computerNumber);
               System.out.println("The guessed number is : " + guess);
               System.out.println("Award : 100 EUR");
           }

           else{

               System.out.println("The computer generated number is : " + computerNumber);
               System.out.println("The guessed number is : " + guess);
               System.out.println("Award : 0 EUR");
           }
       }
   }
}
