What will be the output of the following C# code?
static void Main(string[] args)
{
byte varA = 10;
byte varB = 20;
long result = varA & varB;
Console.WriteLine(“{0} AND {1} Result :{2}”, varA, varB, result);
varA = 10;
varB = 10;
result = varA & varB;
Console.WriteLine(“{0} AND {1} Result : {2}”, varA, varB, result);
Console.ReadLine();
}
a) 0, 20
b) 10, 10
c) 0, 10
d) 0, 0

Answer: c
Explanation: When ‘OR’ operations is done on the binary values following are the results of OR.
‘OR’ means addition(+) operation.
0 (false) + 0(false) = 0 (false)
1 (True) + 0(false) = 1 (True)
0(false) + 1(True) = 1 (True)
1(True) + 1(True) = 1 (True)
When using OR operation it gives FALSE only when both the values are FALSE. In all other cases ‘OR’ operation gives ‘true’.
Output :
10 AND 20 Result :0.
10 AND 10 Result :10.
