Something wrong with for loop

[ianheinze]

So our problem is:

Read in five scores and output the average; then, for each score, output the amount by which that score differs from the average.

For example

Enter a score: 65.8
Enter a score: 99
Enter a score: 87.5
Enter a score: 88
Enter a score: 100

The average is 88.06

65.8 is below average by 22.26
99 is above average by 10.94
87.5 is above average by 0.56
88 is above average by 0.06
100 is above average by 11.94

#include <iostream>
using namespace std;

const int NUM_SCORES = 5;


int main()
{

    int i=0;
    double test_scores[NUM_SCORES];
    double sum=0;
    double average;

    while (i < NUM_SCORES)
    {

        cout << "Please enter the score: ";
        cin >> test_scores[i];
        sum = sum + test_scores[i];
        i++;
    }

    average = sum / NUM_SCORES;
    cout << "The average is " << average;

    for (int i=0, i < NUM_SCORES, i++)
    {
        if (test_scores [i] > average)
        {
            cout << test_scores [i] << " is above average by " << test_scores [1] - average << endl;
        }
        else if (test_scores [i] < average)
        {
            cout << test_scores [i] << " is below average by " << test_scores [1] - average << endl;
        }
        else
        {
            cout << test_scores [i] << " is equal to the average. " << endl;
        }
    }
    return 0;
}

The code runs until it gets to the for loop, which is the only place I encounter any errors. What's wrong with it, and how would I begin to correct it?

Try
for (int i=0; i < NUM_SCORES; i++)

Thanks so much!
