var challenge

Change the code to avoid using type names in variable declarations. Use the var keyword instead. The actual types of the variables should be the same as they were before making any changes.

string input = "22";

int converted = int.Parse(input);

bool wheelsAreRound = true;

string downcased = "DoNuTs".ToLower();

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

double total = 0;

this is my code

var input = "22";

var converted = int.Parse(input);

bool wheelsAreRound = true;

var downcased = "DoNuTs".ToLower();

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

var total = 0.0;

where did i mess up

Hi Joel,

Change the two bools to var as well and you should be fine.
