7.4 (Analyze scores) Write a program that reads an unspecified number of scores and determines how many scores are above or equal to the average and how many scores are below the average. Enter a negative number to signify the end of the input. Assume that the maximum number of scores is 100.
import java.util.Scanner; public class ProgrammingEx7_4 { public static void main(String[] args) { final int MAX_NUMBER_OF_SCORE = 100; Scanner input = new Scanner(System.in); int[] score = new int[MAX_NUMBER_OF_SCORE]; int sum = 0, avg = 0, n = 0; System.out.print("Enter scores (End input with negative number):"); for (int i = 0; i < score.length; i++) { score[i] = input.nextInt(); if (score[i] < 0) { avg = sum / i; break; } else { sum += score[i]; n++; } } int equal = 0, above = 0, below = 0; for (int i = 0; i < n; i++) { if (score[i] == avg) { equal++; } else if (score[i] > avg) { above++; } else { below++; } } System.out.println("The number of scores equal to average is " + equal); System.out.println("The number of scores above average is " + above); System.out.println("The number of scores below average is " + below); } }
