Explanation / Answer

import java.util.Scanner;

class Main {

public static void main(String[] args) {

// declaring variables

int n, i;

Scanner sc = new Scanner(System.in);

// taking user input of number of scores

System.out.print("Enter the number of students: ");

n = sc.nextInt();

System.out.printf("Enter %d scores: ",n);

int[] scores = new int[n];

int best = 0;

// taking user input for scores

// updating the best score as well

for(i=0; i<n; i++)

{

scores[i] = sc.nextInt();

// updating best

if(best < scores[i])

best = scores[i];

}

// looping through each

score and printing grades

for(i=0; i<n; i++)

{

// printing grade

char grade = ' ';

if(scores[i] >= best - 10)

grade = 'A';

else if(scores[i] >= best - 20)

grade = 'B';

else if(scores[i] >= best - 30)

grade = 'C';

else if(scores[i] >= best - 40)

grade = 'D';

System.out.printf("Sutdent %d score is %d and grade is %c ",i,scores[i],grade);

}

}

}

/*SAMPLE OUTPUT

Enter the number of students: 4

Enter 4 scores: 40 55 70 58

Sutdent 0 score is 40 and grade is C

Sutdent 1 score is 55 and grade is B

Sutdent 2 score is 70 and grade is A

Sutdent 3 score is 58 and grade is B
