C# Interview Questions

Select from following answers: 00000null 000000 0null 0 Show Correct Answer

Interesting?  

Brother,

First of all, I thank you for taking efforts in posting this question. I tried implementing this in one of the Console Applications and the output of:

Class A { static byte a; static short b; static char c; static int d; static long e; static string s; Public Static Void Main(String args[]) { Console.WriteLine(a+b+c+d+e+s); } }

is '0 ' and not '0null ' ... Please check it at your end and if possible modify your option ... it will help us guide people in the correct way.

According to me, the correct answer for this question is Option 4 and not Option 3.

No hard feelings ... we all are here to help each other !!!

Niraj is right and I wonder that still the Person posted the Question has not changed the Answer to the Correct one i.e option D.
I think Bro You have guessed the answer logically and have not implemented it.

The specification says the following.
"The binary + operator performs string concatenation when one or both operands are of type string. If an operand of string concatenation is null, an empty string is substituted. "

That explains why the correct answer is 0 (option 4).
