How do I solve this challenge problem?
I keep getting an error that says, "Cannot Implicitly convert Frog.Cs to double."
using System;
namespace Treehouse.CodeChallenges
{
class FrogStats
{
public static double GetAverageTongueLength(Frog[] frogs)
{
double total = 0;
int i = 0;
double sum = 0;
for(; i < frogs.Length; i++)
{
sum = (double)frogs[i];
total += sum;
}
//Console.WriteLine(avg/i);
}
}
}
namespace Treehouse.CodeChallenges
{
public class Frog
{
public int TongueLength { get; }
public Frog(int tongueLength)
{
TongueLength = tongueLength;
}
}
}

for(; i < frogs.Length; i++)
{
sum = (double)frogs[i];
total += sum;
}
I will suggest to use this kind...
for(int i = 0; i < frogs.Length; i++)
{
}
My answer is
namespace Treehouse.CodeChallenges
{
class FrogStats
{
public static double GetAverageTongueLength(Frog[] frogs)
{
double total=0;
for(int i=0;i<frogs.Length;i++)
{
total+=frogs[i].TongueLength; //frogs[i].ToLength is double data type
}
return total/frogs.Length; //average = total / sum of item
}
}
}

Since a frog isn't just a value, it cannot be converted to a double by casting.
You'll also need to take care of these issues:
- after adding the lengths, you'll need to divide by the number of frogs to get an average
- your function will need to return the average value
