Return the average length of the tongues of the frogs in the array. Use a foreach loop as part of your solution. Important: In each task of this code challenge, the code you write should be added to the code from the previous task. Restart Preview Get Help Check Work FrogStats.cs Frog.cs

You have to be aware of types But this is how it's done.

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

            double average = totalTongueLength / frogs.Length;
            return average;
        }
    }
}

Sorry the "for" and "for each" question have a similar title this is the right answer for the FOREACH question.

namespace Treehouse.CodeChallenges
{
    class FrogStats
    {
        public static double GetAverageTongueLength(Frog[] frogs)
        {
            int totalLength = 0;
            foreach(Frog frog in frogs) {
                totalLength += frog.TongueLength;
            }
            double average = totalLength / frogs.Length;
            return average;
        }
    }
}
