Explanation:
You have an upcoming exam and you are confident that you have read all your books and believe you know your stuff down cold. Somehow, after sitting for your exam, you fail. To avoid this from happening again, you can use methods like SQRW or KWL to make sure that you get a better grade. Each of these techniques are initials that stand for “Survey”, “Question”, “Read”, and “Write” (SQRW) and “Know,” “Want to Know,” and “Learned” (KWL) respectively. People who make the most out of these two strategies will understand what they read and prepare notes of what they learned. These notes will come in handy when sitting for an exam. KWL, specifically, help student become better versions of themselves and improve in reading expository text.
Answer:
Both codes are correct.The value of even is true when the number is even.
Explanation:
Code 1:
number %2 ==0 means that when dividing number by 2 is the remainder coming out is zero.If it is true then even becomes is true if it is false then else statement is executes in which even becomes false.Means the number is odd.This code is simple and easy to understand.
Code 2:-
This code is a bit tricky and takes time to understand.even becomes true
when the number is divisible by 0 and false when it is not.
Answer:
The code solution is written in Java.
- import java.util.Scanner;
-
- public class TestScore {
-
- public static void main(String[] args) {
-
- Scanner input = new Scanner(System.in);
-
- System.out.print("Please enter first score: ");
- double firstScore = input.nextDouble();
- System.out.println("Grade: " + determineGrade(firstScore));
-
- System.out.print("Please enter second score: ");
- double secondScore = input.nextDouble();
- System.out.println("Grade: " + determineGrade(secondScore));
-
- System.out.print("Please enter third score: ");
- double thirdScore = input.nextDouble();
- System.out.println("Grade: " + determineGrade(thirdScore));
-
- System.out.print("Please enter fourth score: ");
- double fourthScore = input.nextDouble();
- System.out.println("Grade: " + determineGrade(fourthScore));
-
- System.out.print("Please enter fifth score: ");
- double fifthScore = input.nextDouble();
- System.out.println("Grade: " + determineGrade(fifthScore));
-
- System.out.println("Average score: " + calcAverage(firstScore, secondScore, thirdScore, fourthScore, fifthScore));
-
- }
-
- public static double calcAverage(double score1, double score2, double score3, double score4, double score5){
- double average = (score1 + score2 + score3 + score4 + score5) / 5;
- return average;
- }
-
- public static String determineGrade(double score){
- if(score >= 90){
- return "A";
- }
- else if(score >= 80 ){
- return "B";
- }
- else if(score >=70){
- return "C";
- }
- else if(score >=60){
- return "D";
- }
- else{
- return "F";
- }
- }
- }
Explanation:
Firstly, create the method, <em>calcAverage()</em>, that takes five test scores. Within the method, calculate the average and return it as output. (Line 33 - 36)
Next, create another method, <em>determineGrade()</em>, which takes only one score and return the grade based on the range of the score. (Line 38 -54)
Once the two required methods are created, we are ready to prompt use for input five test scores using Java Scanner class. To use get user input, create a Scanner object (Line 7). Next, use getDouble() method to get an input score and assign it to variables firstScore, secondScore, thirdScore, fourthScore & fifthScore, respectively. Once a score input by user, call determineGrade() method by passing the input score as argument and immediately print out the return grade. (Line 9 - 27)
At last, call calcAverage() method by passing the first test score variables as argument and print out the returned average value. (Line 29).
