Hi. Can somebody explain this to me? I thought this was the right way, but I'm stuck

string language = Console.ReadLine();

if(language == "C#") { System.Console.WriteLine("C# Rocks!"); }

else (language != "C")

{ System.Console.WriteLine(language + " is not C#."); }

CodeChallenge.cs 
string language = Console.ReadLine();

if(language == "C#")
{
  System.Console.WriteLine("C# Rocks!");
}

else (language != "C")

{
  System.Console.WriteLine(language + " is not C#.");
}

:point_right: An else does not take a conditional expression.

The else block is performed for any condition that was not handled by the previous if.

Just remove everything on the line after the else and your code should compile. Or you could convert it into a comment:

string language = Console.ReadLine();

if (language == "C#")
{
  System.Console.WriteLine("C# Rocks!");
}
else //(language != "C#")
{
  System.Console.WriteLine(language + " is not C#.");
}
