Write a program in to input and store all roll numbers, names and marks in 3 subjects of n number of students in five single dimensional
arrays and display the remark based on average marks as given below:
Average marks = total marks/3
AVERAGE MARKS
REMARK
85 – 100
EXCELLENT
75 – 84
DISTINCTION
60 – 74
FIRST CLASS
40 – 59
PASS
Less than 40
POOR
Solution
TC++ #7365
import java.util.Scanner;
public class Marks {
public static void main(String[] args) {

int[] subject3Marks = new int[n];
for (int i = 0; i < n; i++) {
