Hi...
I want to insert a variable finalScore into an array competitorsArray[competitorCounter] . I can't find any instructions anywhere on how to do this, so I'm wondering if it's even possible.
Also, how do I output an error message if the user enters a number that I then store into an array if the number is not within certain parameters, ie the number should be between 0.0 and 6.0 and only be in increments of 0.1, only one decimal place?
I've included my original code with comments as to what I would like to do and what I've already tried.
Thanks in advance for any help. btw I'm a newbie at C++ :)

### The problem should prompt the operator to enter the
number of competitors, followed by the scores awarded to each
by the 5 judges. Scores can range from 0.0 to 6.0 in increments of 0.1.
Invalid scores entered by the operator should result in an error message
being displayed. To calculate the final score to be awarded to each
Diving Competitor, the highest and lowest scores are ignored and
the remaining scores are averaged to give the final score,
which is then displayed. The problem should continue
until specifically terminated.
