980 PointsThis challenge does not make sense to me....
...because the I believe I did everything correctly but I am getting the error message: FrogStats.cs(13,30): error CS0019: Operator +' cannot be applied to operands of typeTreehouse.CodeChallenges.Frog' and `double'"... Well sure, that is because the type "Frog[] does not even exist! Arrays must be either of type: int, double, float or string not "Frog". How am I suppose to then use "+", "/" or any other normal math operator to get an average???
namespace Treehouse.CodeChallenges
{
class FrogStats
{
public static double GetAverageTongueLength(Frog[] frogs)
{
double total = 0;
double AverageTongueLength = 0;
for(int index = 0; index < frogs.Length; index++)
{
total = frogs[index] + total;
}
return AverageTongueLength = total / frogs.Length;
}
}
}
namespace Treehouse.CodeChallenges
{
public class Frog
{
public int TongueLength { get; }
public Frog(int tongueLength)
{
TongueLength = tongueLength;
}
}
}

Courses Plus Student 27,294 PointsYou seem to be getting that error in your for loop:
total = frogs[index] + total;
frogs[index] will return a Frog object, total is an int. So you are trying to add an int to a Frog which won’t work :)
You need to get the tounge length from each Frog in the frogs array. Try using some dot notation on: frogs[index].
