What is output from the following code snippet?
int a = 10;
int? b = null;
int c = 20;
Console.Write(a + (b ?? c));
The ?? is a null coalescing operator, if b is null then use c else use b, so for the snippet in the code the sum carried out is actually a + c as b is set to null, if b had a int value then the sum would have been a + b.
