# Array: Analyze scores

Question: 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 the maximum number of scores is 100.

Example:

Enter scores:
89
Enter scores:
90
Enter scores:
96
Enter scores:
56
Enter scores:
23
Enter scores:
78
Enter scores:
63
Enter scores:
20
Enter scores:
98
Enter scores:
99
Enter scores:
100
Enter scores:
100
Enter scores:
100
Enter scores:
-4
Average: 77
Scores greater or equal to average: 89 90 96 78 98 99 100 100 100
Scores less than average: 56 23 63 20

Step 1: Create an array of size 100
Step 2: Input the scores (When negative number is entered terminate the loop)
Step 3: Calculate the average score
Step 4: Display cores that are above average
