It asks me to Add a constructor to the Frog class that accepts a tongue length parameter value. Though I don't know if I have to assign it with variable.
namespace Treehouse.CodeChallenges
{
class Frog
{
public readonly int TongueLength;
}
}

In task 3 you'll be asked to use the parameter to initialize the field.

Courses Plus Student 13,331 Pointsthat is what I do in task 2 but still there's an error : Frog.cs(5,30): error CS0106: The modifier `readonly' is not valid for this item Compilation failed: 1 error(s), 0 warnings

Courses Plus Student 13,331 PointsI enter the curly brackets though it gives me that error

231,268 PointsThe code sample above shows task 1 completed, but no code for task 2 yet.
If you're having an issue with task two, please show the code with the task 2 changes included.

Courses Plus Student 13,331 Pointsyou are right I didn't do much of a difference though to me it looks right to me. thanks for trying your best to explain though I still am not 100% sure what I did wrong could show me the code so I could refer.

231,268 PointsCheck out the video example, where a constructor is created for the "Map" class.
Tojo Alex
Courses Plus Student 13,331 PointsOK now this is what I done: namespace Treehouse.CodeChallenges { class Frog { public readonly int TongueLength;
Frog(int TongueLength)
{
}
}
} The error now is :Did you declare the 'Frog' constructor with the 'public' access modifier?
Steven Parker
231,268 PointsBased on the error message, you might try putting the word "public" in front of the constructor name "Frog".
And when posting code, please use the instructions for code formatting in the Markdown Cheatsheet pop-up below the "Add an Answer" area.

Courses Plus Student 13,331 Pointsthanks alot

Courses Plus Student 13,331 PointsNow in challenge 3 It says: Frog.cs(10,35): error CS0103: The name `tonguelength' does not exist in the current context Compilation failed: 1 error(s), 0 warnings Code: namespace Treehouse.CodeChallenges { class Frog { public readonly int TongueLength;
public Frog(int TongueLength)
{
TongueLength = tonguelength;
}
}
}
Steven Parker
231,268 PointsThe parameter name should be "tongueLength" (little "t", capital "L"). But at the moment it has a capital "T" in the definition, and a little "l" in the assignment.
For any future questions, please format your code using the instructions/video I mentioned previously.
Tojo Alex
Courses Plus Student 13,331 Pointsthanks I figured it out
Tojo Alex
Courses Plus Student 13,331 Pointsnamespace Treehouse.CodeChallenges { class Frog { public readonly int TongueLength; {
}
}
}

231,268 PointsOther than the lack of formatting, The only difference I can see is a pair of braces.
But a constructor will look much like a method, with a name, arguments with specified types in parentheses, and then braces enclosing a code block. You may want to take another look at the example built in the Initialization video, starting about 20 seconds in.
And when posting code, use the instructions for code formatting in the Markdown Cheatsheet pop-up below the "Add an Answer" area.
