Question

Write a program which can be used to calculate bonus points to given scores in the range [1..9] according to the following rules:

 If the score is between 1 and 3, the bonus points is the score multiplied by 10

 If the score is between 4 and 6, the bonus points is the score multiplied by 100

 If the score is between 7 and 9, the bonus points is the score multiplied by 1000

 For invalid scores there are no bonus points (0) Your program must make use of 2 parallel arrays – one to store the scores and the other to store the bonus points. You need to make provision for 5 scores (and bonus points) that will need to be stored.

For this program implement the following methods and use these methods in your solution (do not change the method declarations):

static void getScores(int[] scores)

static void calcBonus(int[] scores, int[] bonusPoints)

static void displayAll(int[] scores, int[] bonusPoints)
