C++
In this program, I had to read in a text file from a judging competition where there were 10 players with 6 scores each. The highest and lowest score for each player was thrown out and the remaining four are averaged to calculate their score. Then, first place, second place, third, and so on are displayed with their average score next to them. I have functions for lowest and highest (I think), but I don't know how to pass data into them. The text file and my code are below.
To reiterate, my problem is that I need to eliminate the highest and lowest score for each player using functions and then display, in order, their place in the competition.
Text File:
"Competition.txt"
