Stuck on Frog Tongues. I am getting compile errors that don't show up in Visual Studio.

Hi, Can someone give my code a second peek? It says I have compile errors and I am not sure why. Thank you!

FrogStats.cs 
using System;
namespace Treehouse.CodeChallenges
{
    class FrogStats
    {
        public static double GetAverageTongueLength(Frog[] frogs)
        {
            double sumTongues = 0.0;
            double result = 0.0;
            for (int i = 0; i < frogs.Length; i++)
            {
                sumTongues += double.Parse(frogs[i]);
            }
            result = sumTongues / frogs.Length;
            return result;
        }
    }
}
Frog.cs 
namespace Treehouse.CodeChallenges
{
    public class Frog
    {
        public int TongueLength { get; }

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

You're pretty close, but...

  • you don't need double.Parse because the lengths are already numbers (not strings)
  • you can't add the frog itself, you need to select the TongueLength property

Oh, I thought I understood objects, Now I am not sure how to grab a ToungeLength property out of the object Frogs[].

The "dot notation" is a most common way to select a property: "objectname.propertyname". Or in this case, since you're also selecting an object from an array with an index: "objectarrayname[index].propertyname".

And don't forget your object array is frogs (with a lower-case "f").

Thank you, Steven. I changed my sumTongues to an int so I didn't have to convert, I then accessed the toungueLength as you stated. Finally, divided as before and made it a double called result. Worked. I guess when you divide two ints and the answer is a double you can use double.
