C# challenge

Am i getting closer?

FrogStats.cs 
namespace Treehouse.CodeChallenges
{
    class FrogStats
    {
        public static double GetAverageTongueLength(Frog[] frogs)
        {
        for(i = 0; i < frogs.length; i++;)
            {
            return 
            }
        }
    }
}
Frog.cs 
namespace Treehouse.CodeChallenges
{
    public class Frog
    {
        public int TongueLength { get; }

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

Closer than what? But some issues here are:

  • the loop has a stray extra semicolon after the increment clause
  • the return statement is missing a semicolon
  • the return should be placed after of the loop instead of inside it
  • the return should pass back a double value
  • the code to compute the average still needs to be added (both inside and around the loop)

I get what an average is, but Im not sure how to express it in code. Would you give me the first step?

Typically, you build up a sum in the loop, then after it ends, divide the sum by number (Length) of items.
