Question

Array testGrades contains NUM_VALS test scores. Write a for loop that sets sumExtra to the total extra credit received. Full credit is 100, so anything over 100 is extra credit. Ex: If testGrades = {101, 83, 107, 90}, then sumExtra = 8, because 1 + 0 + 7 + 0 is 8.

Java COde:

import java.util.Scanner;

public class SumOfExcess {
public static void main (String [] args) {
Scanner scnr = new Scanner(System.in);
final int NUM_VALS = 4;
int[] testGrades = new int[NUM_VALS];
int i;
int sumExtra = -9999; // Assign sumExtra with 0 before your for loop

for (i = 0; i < testGrades.length; ++i) {
testGrades[i] = scnr.nextInt();
}

/* Your solution goes here */

System.out.println("sumExtra: " + sumExtra);
}
}

import java.util.Scanner;

public class SumOfExcess {
    public static void main (String [] args) {
        Scanner scnr = new Scanner(System.in);
        final int NUM_VALS = 4;
        int[] testGrades = new int[NUM_VALS];
        int i;
        int sumExtra = -9999; // Assign sumExtra with 0 before your for loop

        for (i = 0; i < testGrades.length; ++i) {
            testGrades[i] = scnr.nextInt();
        }

        sumExtra = 0;
        for (i = 0; i < testGrades.length; ++i) {
            if(testGrades[i]>100){
                sumExtra += (testGrades[i]-100);
            }
        }

        System.out.println("sumExtra: " + sumExtra);
    }
}
