could someone who has experience walk me through this ive been stuck for sometime i feel like im close but then i feel like im way off
namespace Treehouse.CodeChallenges
{
class FrogStats
{
public static double GetAverageTongueLength(Frog[] frogs)
{
for(double i = 0; i < frogs.length; i++)
{
return i.Average();
}
}
}
}
namespace Treehouse.CodeChallenges
{
public class Frog
{
public int TongueLength { get; }
public Frog(int tongueLength)
{
TongueLength = tongueLength;
}
}

231,236 PointsPerhaps these hints will help:
- the correct spelling of the "Length" property is with a capital "L"
- it's more common to use an
int
as a loop index - numbers (either doubles or ints) have no "Average" method
- an unconditional "return" inside a loop will end the function on the very first iteration
- a good use of the loop might be to accumulate a total of the lengths
- after the loop ends, the average could be determined by dividing the total by the array length

4,510 Pointsnamespace Treehouse.CodeChallenges { class FrogStats { public static double GetAverageTongueLength(Frog[] frogs) { total += frogs[i].TongueLength; for(int i = 0; i < frogs.Length; i++) { return total/frogs.length;
} } } } am i close?
