Question

When I conpile this code:

BitArray bits = new BitArray(3); bits[0] = true; bits[1] = true;  bits[2] = true;  BitArray moreBits = new BitArray(3); bits[0] = true; bits[1] = true; bits[2] = true;  BitArray xorBits = bits.Xor(moreBits);  foreach (bool bit in xorBits) { Console.WriteLine(bit); } 

I get the following output:

True True True

When I do an xor on two boolean values by saying true ^ true i get false.

Is there something wrong with the code. My memory of the truth table for XOR was that True XOR True is false.

Answer 1

Copy and paste error.

BitArray moreBits = new BitArray(3); bits[0] = true; bits[1] = true; bits[2] = true; 

That should be:

BitArray moreBits = new BitArray(3); moreBits[0] = true; moreBits[1] = true; moreBits[2] = true;
