The function "Console.Read()" returns a single character, represented as an integer code value.

:point_right: You probably want "Console.ReadLine()", which returns an entire line as a string.

            string line = Console.ReadLine();

Otherwise, good job! :+1: This is one of the tougher challenges, based on the frequency of posts about it.

Happy coding!   -sp:sparkles:

Thank you Steven. Unfortunately, still it gives me the error Bummer! Your code could not be compiled. Please click on "Preview" to view the compiler errors.

That's the difference between Console.Read and Console.ReadLine. The first returns int, and the second returns string.

I guarantee that you will not see that error once you have changed that line.
