    {
        public static double GetAverageTongueLength(Frog[] frogs)
        {
            double total = 0;
            int i = 0;
            for(i <= frogs.Length; i++)
            {
                total += frogs[i];
            }
            return total/i;
        }
    }

The message is a bit misleading, but it looks like there are 3 issues:

  • the "for" loop needs an initialization clause, even if it is empty
  • the loop should stop before reaching the array "Length"
  • you can't add "frogs", add their tongue lengths instead:
            for ( ; i < frogs.Length; i++)       // empty init clause, and stop BEFORE Length
            {
                total += frogs[i].TongueLength;  // add lengths not frogs
