Question

1.

Write a program that randomly generates 10 whole numbers between 0 and 100 and stores them into an array. The program then calculates the average and displays the average and the numbers that are above the average. Use loops where needed. Must be stored in an array. Must be done using C++.

2.

Write a program that reads 8 student scores, between 0 and 100, finds the best score, and then assigns grades based on the following scheme. Must use loops where needed. Must be done using C++.

​Grade is A if score >= best – 10

Grade is B if score >= best – 20

Grade is C if score >= best – 30

Grade is D if score >= best – 40

import java.util.*;

public class Average {
    public static void main(String[] args)
    {
        Random r = new Random();
        int nxt;
        int[] arr = new int[10];
        float avg = 0;
      
        System.out.println("\nRandomly generated 10 numbers are :\n");
        for(int i = 0; i < 10; i++)
       {
           nxt = r.nextInt(100);
           arr[i] = nxt;
           avg += nxt;
          
           // Printing the random Number
           System.out.print(nxt+" ");
       }
       avg = avg/10;
       System.out.printf("\n\nAverage is %.2f\n", avg);
      
        System.out.println("\nNumbers above average are :");
        for(int i = 0; i < 10; i++)
       {
           if(arr[i] > avg)
               System.out.print(arr[i]+" ");
       }
       System.out.println("\n");
   }
}
