so
the
formulae
is
sum of points of each market /number of times rated.
Note: Program solution must use functions and arrays only.
Download rating.txt from moodle.
Rating.txt is containing 100 records, so you may declare array size as 100 as a global variable.

dividing by number of times it has been rated.
