Could someone please explain this to me thank you

I cant understand the question ?

CodeChallenge.cs 
string input = "22";

int converted = int.Parse(input);

bool wheelsAreRound = true;

string downcased = "DoNuTs".ToLower();

bool success = (downcased == "donuts");

double total = 0;

You can use var to declare a variable if the type can be inferred. So the exercise would look like this:

var input = "22";

var converted = int.Parse(input);

var wheelsAreRound = true;

var downcased = "DoNuTs".ToLower();

var success = (downcased == "donuts");

var total = 0.0;

The only other change, than substituting var, is that ou need to change 0 to 0.0 in the last line so C# will infer double rather than int.
