2,440 PointsFor loop can't compile due to error CS0019, how can this be rectified?
I am trying to find the average of an array of integers. I feel that my code meets this criteria but I keep being told that it cannot compile due to the +=
operator won't work on a type int
and a type Treehouse.CodeChallenges.Frog
.
I have tried everything I can thing of for now but I am a beginner, am I missing something obvious?
Thanks.
namespace Treehouse.CodeChallenges
{
class FrogStats
{
public static double GetAverageTongueLength(Frog[] frogs)
{
int total = 0;
double average = 0;
for(int i = 0; i < frogs.Length; i++)
{
Frog frog = frogs[i];
total += frog;
}
return average = total/frogs.Length;
}
}
}
namespace Treehouse.CodeChallenges
{
public class Frog
{
public int TongueLength { get; }
public Frog(int tongueLength)
{
TongueLength = tongueLength;
}
}
}

231,269 PointsYou can't add a "frog" to a number. You probably wanted to add the tongue length:
total += frog.TongueLength;
And a "return" statement takes an expression but not an assignment:
return total/frogs.Length;
So you also don't need the "average" variable.
