error CS0019: Operator `+' cannot be applied to operands of type `int'

I always get compiler error that i cannot sum int or double ... i tried both and check in internet too but I cannot find the reason for that.

I'll bet there's something else causing the issue. Please show your complete code here for analysis, or provide a link to a workspace snapshot.

OK sorry I thought the code was attached. I agree that there must be something else :) but I don't get WHAT is causing it. Here you can see my solution ... namespace Treehouse.CodeChallenges { class FrogStats { public static double GetAverageTongueLength(Frog[] frogs) { int SumLength = 0;

        for (int i =0; i < frogs.Length; i++)
        {
            SumLength += frogs[i];            
        }
        return SumLength / frogs.Length;
    }
}

}

Oh I see now, you can't add a "frog" to an int. You probably meant to add the frog's tongue length:

            SumLength += frogs[i].TongueLength;

Erich Freimann — Mistakes are just "learning opportunities". :wink:

Glad I could help. You can mark the question solved by choosing a "best answer".

And happy coding!
