Could someone tell me what this line of code mean


int? id, bool? saveChangesError=false



public ActionResult Delete(int? id, bool? saveChangesError=false)
{
    if (id == null)
    {
        return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
    }
    if (saveChangesError.GetValueOrDefault())
    {
        ViewBag.ErrorMessage = "Delete failed. Try again, and if the problem persists see your system administrator.";
    }
    Student student = db.Students.Find(id);
    if (student == null)
    {
        return HttpNotFound();
    }
    return View(student);
}

It is specifying that id is a Nullable<int> and saveChanges is a Nullable<bool> with a default value of false.
