/*
Notes & Comments:
- string.h is required for memcpy
- math.h is required for roundf function
- arrays were used to maintain sanity
- flush used after scanf's
- numbers[10] contains 10 numbers that are from user input
- rounded[10] is same as numbers[10], but rounded with roundf after
- average carries the average of the values in numbers array
