Problem of if/else

Question

I thought when typing 
string entry = Console.ReadLine(); 
in the first line already means that whatever words are entered, the words will show up as the string language. What is the problem in this program? And how could I print out the words that are entered?
Thanks for the reply!
```CodeChallenge.cs
string language = Console.ReadLine();
if(language == "C#")
{
  System.Console.WriteLine("C# Rocks!");
}
else
{
  System.Console.WriteLine(language + "is not C#");
}
```

Your code is fine, language is equal to what was entered into to the program. But one thing to take notice of is that when you combine strings together they are merged without adding any spaces between them. Therefore in order to produce a sentence with proper spacing you have to add one manually. Either by adding a string that just contains a space, like this:
csharp
language + " " + "is not C#"

Or by adding a space at the start of the next string like this:
csharp
language + " is not C#"

Either way is fine, but you do have to do something to produce that space. The challenge checker for these challenges is pretty strict about text output. If it asks for a sentence with certain spacing it will mark your code as wrong it doesn't get exactly the sentence it wanted.
