Question

I just created a simple project with if statements to check if the statement is true, but then I stumbled into something weird.

This is my sample code

 if(x ==1)
    {
      do something;
    }

 else if( x==2)
    {
      do something;
    }
else if( x==3)
    {
      do something;
    }
else if( x==4)
    {
      do something;
    }

    {
      do something;
    }

nope, you read that right. And I typed that right also. I have left out the else statement, but I have created curly brackets for it. When I compile, it runs fine. Is this some kind of bug? Or am I just new to this? I just wanted to know. Thanks for all the answers

Answer 1

Your last code block without an if/else if will execute. Curly braces are for code separation, and don’t require conditional/iteration or any other precursor to have meaning.

For an exageration to further explain my point:

{
    {
        Console.WriteLine("This works");
        int i;
    }
    // the variable i is out of scope and can't be referenced here
}

That is possible, as well.

As per @slugonamission‘s comment, he brought up a great point. The code block also creates a scope isolation for variables that are created inside of this code block.
