foreach loops: I don't understand how to iterate through the array

namespace Treehouse.CodeChallenges { class FrogStats { public static double GetAverageTongueLength(Frog[] frogs) { double sum = 0; double average = 0;

        foreach(Frog frog in frogs)
        {
            sum += frogs[i].TongueLength;
        }

        average = sum/frogs.Length;
        return average;
    }
}

}

:point_right: It looks like you mixed for and foreach loop syntax.

Inside your loop, you try to subscript frogs using an index named i, but you haven't declared an "i" variable. You might have created an "i" in a for loop, but since you used a foreach loop you created a "frog" variable instead.

So inside your loop, you probably want something like this:

            sum += frog.TongueLength;

In any future postings, be sure to include a link to the challenge page.

Got it now, thanks! I knew it was something wrong with the syntax.
