Answer:
Giving that: The following is a sequence of undo-log records written by 2 transactions T and U:
< START T >;
< T,A,10 >;
< START U >;
< U, B, 20 >;
< T, C, 30 >;
< U, D, 40 >;
< Commit U >;
< T, E, 50 >;
< Commit T >;
1. < START U >
Recovery action in this case will be undo(-1) and undo(0). All restored to its original Value
log records < T, A, 10 >, < T, abort >; as written out
2. < T, E, 50 >
Recovery action in this case will be undo(8) and redo(0). A and C is restored to its original value, B and D are set to 20 and 40
log records <T, C, 30 >, < T, A, 10 >, < T, abort > are written out
3. < Commit T >
Recovery action in this case will be redo(7) and redo(4). A and C are set to 10 and 30, B and D are set to 20 and 40

Answer:
ranforce = randi([0, 12]);
if (ranforce == 0)
disp('There is no wind')
else if(ranforce>0 && ranforce <7)
disp('There is a breeze')
else if(ranforce>6 && ranforce <10)
disp('This is a gale')
else if(ranforce>9 && ranforce <12)
disp('It is a storm')
else if(ranforce==12)
disp('Hello, Hurricane!')
end
Explanation:
<em>Replace all switch case statements with if and else if statements.</em>
<em>An instance is:</em>
<em>case {7,8,9}</em>
<em>is replaced with</em>
<em>else if(ranforce>9 && ranforce <12)</em>
<em>All other disp statements remain unchanged</em>
Answer:
import java.util.Scanner;
public class num6{
static int getTestScores(){
System.out.println("Enter the Score");
Scanner in = new Scanner(System.in);
int score = in.nextInt();
return score;
}
static double calcAverage(int score1, int score2, int score3){
return (score1+score2+score3)/3;
}
static void displayAverage(double ave){
System.out.println("The Average is "+ave);
}
public static void main(String[] args) {
int num1 = getTestScores();
int num2 = getTestScores();
int num3 = getTestScores();
//Calling Calculate Average
double average = calcAverage(num1,num2,num3);
//Calling displayAverage
displayAverage(average);
}
}
Explanation:
- Using Java programming Language
- Create the four methods
- getTestScores() Uses the Scanner Class to receive an in variable and return it
- calcAverage() accepts three ints as parameter calculates their average and return it
- displayAverage() Accepts a double and prints it out with a concatenated string as message
- In the Main Method, getTestScores is called three times to obtain three numbers from the user
- calAverage is called and handed the three numbers
- printAverage is called to output the calculated average
