I think I got the loop right, but I can't figure out how to get the variable of the TongLength into the for loop. At least, I assume this is necessary. I think from there I can, I hope :), figure out how to return the average, but all the help is welcome atm... please check out my code if you can help, thank you in advance!
namespace Treehouse.CodeChallenges
{
class FrogStats
{
double _frog = 0;
public static double GetAverageTongueLength(Frog[] frogs)
{
for (int index = 0; index < frogs.Length; index++)
{
double _frog = tongueLength + _frog;
}
double average = _frog / frogs.Length;
return average;
}
}
}
namespace Treehouse.CodeChallenges
{
public class Frog
{
public int TongueLength { get; }
public Frog(int tongueLength)
{
TongueLength = tongueLength;
}
}
}

But you also can't access your "_frog" variable after the loop if it is declared inside the loop. Plus you can't add to it and declare it at the same time. For both of those reasons, you'll want to declare it before the loop. But you probably don't want it to be a class variable.

9,961 PointsThanks for helping out! I had been trying some stuff so yes, I need to use the capital T and I declared _frog twice now I see, so I deleted "double" before the _frog in the for loop... what do you mean with that I don't want is to be a class variable? do I need to put private in front of it?
I am watching back the video's on properties, but I still haven't figured it out...
(I think I voted -1 by accident, sorry! still new to this platform. I think now it got a +1 :))

To access the property, you need to get from a "frogs" instance, like this: "frogs[index].TongueLength".
