min and max values

Nov 30th, 2005

I know you don't do homework for people. But I'm not really sure where else to turn to, because my online tutor for my class isn't really helping. I'll show you the code I have. (I worked about 6 hours on it, honestly. I'm really really bad at this.) If you don't want to help, I understand.

The problem is: In a gymnastics or diving competition, each contestant's score is calculated by dropping the lowest and highest scores received and then adding the remaining scores. Write a program that allows the user to enter eight judges' scores and outputs the points received by the contestant. Format your output with two decimal places.

Here is what I have: (Please don't make fun of the fact that it just took me 6 freaking hours to do this.) My error is with the max and min element. I've never used that before. In fact, I just found them at the back of the book. We haven't actually gotten to algorithms. I couldn't think of anything else to use to find the highest and lowest scores. Thanks so so much if anyone replies!!!!!!

The code in BLUE it is where i change/add. The min_element and max_element is a function that return the maximum and minimum value.
