I am unable to finish both the objective 'For Loops' and 'Foreach Loops' , because unable get the var tongueLength

I have tried multiple things, however I am stuck. This is my code for the objective: 'For Loops'. Thanks in advance, Jesse.

public static double GetAverageTongueLength(Frog[] frogs)
    {

        for (int i = 0; i > 0; i++)
        {
         Frog frogs = Frog[i];
         return ( frog.TongueLength / frogs.Length );
        }
    }

This code would not return the average of all lengths, or loop through all the frogs. Since the "return" is placed inside the loop, it would return during the very first pass.

Here's a few hints for fixing it:

  • create a variable to accumulate a sum of all the lengths
  • inside the loop, add the current length to the sum
  • after the loop finishes, compute the average using the sum instead of just one length
  • return the final average

Yes, I think a got a lot further. Getting a very simpel error do. Haved tried multiple things to solve it. No succes yet. This is my code.

namespace Treehouse.CodeChallenges { class FrogStats {

    public double GetAverageTongueLength(Frog[] frogs)
      {
          double sum;

          for (int i = 0; i > 0; i++)
             {
                  sum +=frogs[i];
             }

          return (sum / frogs.Length);
       }
 }

}

The error I get: "error CS0019: Operator +=' cannot be applied to operands of typedouble' and `Treehouse.CodeChallenges.Frog'"

I have tried changing the operands type, no luck...

You can't add frogs, but you can add the TongueLength of each frog. :wink:
