Hey all. I'm trying to get the FindDaysOver function to grab the avg result from the CalcAvg function result in main. What am I doing wrong? Any help would be appreciated!

#include<iostream>
		#include <iomanip>
		using namespace std;

		double FindMax(double [], int); 
		double FindMin(double [], int);
        	double CalcAvg(double [], int);

Thanks to your formatting your code is extremely difficult to read. I can't even find FindDaysOver()

Reformat using this link and repost.

Cool! I used the online compiler at code pad and received a system fork error. I wasn't sure if it was the compiler or my code. I can't wait to get off work and run it at home! I'll post if I'm successful. Is it possible to keep this thread open til then?
