Ive been struggling with this for a week now and in the course a excample for this was not given.

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

FrogStats.cs 
namespace Treehouse.CodeChallenges
{
    class FrogStats
    {
        public static double GetAverageTongueLength(Frog[] frogs)
        {
            for(double i = 0; i < frogs.length; i++)
            {
              return i.Average();  
            }
        }
    }
}
Frog.cs 
namespace Treehouse.CodeChallenges
{
    public class Frog
    {
        public int TongueLength { get; }

        public Frog(int tongueLength)
        {
            TongueLength = tongueLength;
        }
    }
}

Perhaps 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

namespace 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?

Closer, but you need to declare the total before the loop, accumulate the total inside the loop, and return the average after the loop ends.

Also, be sure to use Markdown formatting when posting code.
