n++; and ++n;!
You've probably used them to increment variable
n, but that's not just what they're used for.
n = 3;. Let's now do this:
Console.WriteLine(n++);. Yes, that's right,
++n are expressions!
return n, then increment n. So
Console.WriteLine(n++); will print 3!
n = 3; again.
++n will increment n, then return n.
Console.WriteLine(++n); will print 4!
+= is like
++n;. So if
n = 3; again,
Console.WriteLine(n+=10); will increment n by ten, then print n! So this will print 13!
So@HahaYes will find this works as well.
