This function will take an array of Frog class instances, all of which has a TongueLength property. You need to calculate the average of those and return it.

  • You can declare a "sum" variable which accumulates the sum of the TongueLengths.
  • Loop through the array to add each TongueLength to this sum. Note that you can not use foreach loop here because the challenge demands for loop
  • return the sum divided by the size of the array, this way perfectly calculating the average
            int sum = 0;
for (int i = 0; i<frogs.Length; i++)
{
  sum += frogs[i].TongueLength;
}
return sum / frogs.Length;
