Design a grade average program that will produce the numerical grade average of test scores input by a user.
The program design should address the following issues:
- Use an Array as the data structure to store the input grades.
- Use a Looping structure to initialize the elements of this array to clear out system garbage.
- The user may input up to 5 test scores.
Hint: This does not mean each user will input 5 scores. 3 scores may be entered for calculation.
- Use a Looping structure to traverse the elements of the array to produce your calculation.
