The order matters because the program read from top to buttom

  • Parse heightInput to an integer so that height = 168
  • Then add 10 to height

but your order is

  • Setting **height* to 10
  • Then parse heightInput to an integer and then set height to 168
string heightInput = "168";
int height;  // here height is = 0

height = height + 10; // now you're adding 10 to height

height = int.Parse(heightInput); // here you set height to 168
