2,201 PointsStumped on how to write the code to determine average length of the frog tongue after the for loop
Is it possible to declare a variable averageLength and define it as sum of the lengths of the tongues of the frogs in the frogs array then divide this by the index of the frogs array? I read somewhere that you cannot perform math on arrays or their indexes.
var averageLength = sum TongueLengths /frogs[i].TongueLength
namespace Treehouse.CodeChallenges
{
class FrogStats
{
public static double GetAverageTongueLength(Frog[] frogs)
{
for(int i = 0; i < frogs.Length; i++)
{
Frog frog = frogs[i];
}
var sum = ______;
int averageTongueLength = sum / frogs[i];
return averageTongueLength
}
}
}
namespace Treehouse.CodeChallenges
{
public class Frog
{
public int TongueLength { get; }
public Frog(int tongueLength)
{
TongueLength = tongueLength;
}
}
}

namespace Treehouse.CodeChallenges
{
class FrogStats
{
public static double GetAverageTongueLength(Frog[] frogs)
{
int Total = 0;
for(int i = 0; i < frogs.Length; i++)
{
Total += frogs[i].TongueLength;
}
return (Total / frogs.Length);
}
}
}
// frogs[i].TongueLength;
// TongueLength is an integer and is an attribute of the Frog object.
// In this case it is the only attribute of the Frog object.

2,201 PointsHi Damien, thank you! Your explanation helps a lot. I am going to mark your answer best answer here.
I also came up with code that I think solves the problem (not quite yours though) and I would appreciate if you take a look at it as well: link
Thanks again

2,201 PointsThanks, Damien. I see how it would work.
Aside from the solution, your comments below your solution code indicate that Frog is an object. How did you determine that - isn't Frog a class?

As I understand it, a class is like a blueprint for making an object. When you instantiate a class you are creating an instance of the object (I used the cake recipe to make a single cake). Inside the for-loop you tried to do this (Frog frog = frogs[i];). However in this example there is no need for this. The method GetAverageTongueLength accepts a array parameter named frogs which is of type Frog[]. "frogs" is an array of Frog objects but it is also an object which has already been created and is passed to the method. The for-loop iterates through the array of Frog objects and.... well you know the rest. You were thinking along the right track.
Anyway I hope this helps and please remember to mark/accept my answer "up" if it did!
