I'm getting a CS0019 compiler error with this code. It seems as if I can't add the array elements to the sum because it doesn't think they are of type int. Do I need to call the get accessor in the Frog Class to retrieve these values?
namespace Treehouse.CodeChallenges
{
class FrogStats
{
public static double GetAverageTongueLength(Frog[] frogs)
{
int sum = 0;
double avg;
for (int i = 0; i < frogs.Length; i++)
{
sum += frogs[i];
}
avg = (double) sum / frogs.Length;
return avg;
}
}
}
namespace Treehouse.CodeChallenges
{
public class Frog
{
public int TongueLength { get; }
public Frog(int tongueLength)
{
TongueLength = tongueLength;
}
}
}

The type of "frogs[i]" is Frog.
On the other hand, the type of "frogs[i].TongueLength" would be int.
