Compiler error in for loop code challenge.

I keep running into a compiler error where GetAverageTongueLength has code paths that don't return values. Here's my code.

namespace Treehouse.CodeChallenges { class FrogStats { public static double GetAverageTongueLength(Frog[] frogs) { for(int i = 0; i < frogs.Length; i++) { Frog toad = frogs[i]; } } } }

namespace Treehouse.CodeChallenges { public class Frog { public int TongueLength { get; }

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

}

Again, no idea why this doesn't work. Help?

:point_right: Your GetAverageTongueLength function has no return statement in it.

So there are actually no code paths that return a value, but it is incomplete in other ways also. Since the purpose is to get an average value of tongue lengths, you probably want to accumulate a total inside the loop. Then, after the loop, you could divide that total by the number of frogs to get the average. This average would be the value to return.

I'm really surprised the foreach wasn't covered.. foreach(Invader invader in invaders)
