Initializing a String

I am asked to Initiate bookTitle with my favorite book.

my code is:

string booktitle;

string bookTitle = "It";

Can't figure out what I'm doing wrong.

Thanks, Greg

The type of a variable (string in this case) should only be included when you first create a variable. Not when you reference or change an existing variable.

By using it on both lines you tell C# to create the variable twice within the same method, which is invalid.

So the second line should simply be this:

string bookTitle;
bookTitle = "It"; // Removed string keyword from second line

But for this challenge you are actually expected to merge the two lines together, so you have the declaration and assignment on the same line like this:

string bookTitle = "It";

That is not something you have to do to have valid C# code, but is what this specific challenge expects your code to look like.
