I don't know why I am wrong

Hello, The assignment is to Create a Frog instance in Program.Main() and assign it to a variable named mike. I don't know why I am wrong. Thank you for the help

Program.cs
namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {            
           Frog mike = new Frog ();
        }
    }
Frog.cs
namespace Treehouse.CodeChallenges
{
    class Frog
    {

    }
}

Heya Jeremy,

It is the space between Frog and ()

Frog mike = new Frog();

To clarify, your code compiles in Visual Studio because C# ignores whitespace. You can read about that here .

Therefore, it is the treehouse test that is not passing it correctly as the C# compiler compiles your code for me just fine (Visual Studio Express 2017).

Of course, we should always follow the coding conventions of the languages we use though. That is where we would want to make sure that we are not placing a space between Frog and () as you have done. You can read about coding conventions for c# here .

Regards,

Chris

Parenthesis together. When you initialize an object you use the keyword "new" the name of the class and without space in between a pair of parenthesis.

Frog mike = new Frog();

Same thing when you call an existing method

someMethod();

or when you create an array

int[] a = new int[3];

in this case, these are not parenthesis, but brackets. The general idea is the same, do not add a space, otherwise, the compiler won't understand what your code is trying to do.
