Yes, it short circuits. Class Program { public static void Main() { string s = null; string s2 = " WriteLine(s2?S.ToString()); } } The above program outputs "" rather than throwing a NullReferenceException.

Yes. Public Form1() { string string1 = "test"? Test(); MessageBox.

Show(string1); } private string test() { MessageBox. Show("does not short circuit"); return "test"; } If it did not short circuit, test() would be called and a messagebox would show that it "does not short circuit".

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
