Explain the bitwise operation when XORing a positive and a negative integer (in two's complement representation).

(I mean vector in the mathematical sense, i.e. it has fixed length. Do not confuse this with the C++ data structure std::vector , which has variable length.)We ... Oct 1, 2018 ... When you go back to C/C++ after a week of coding in Python, funny things can happen. ... By the same token (pun intended!), 'xor' and 'xor_eq' ... Apr 1, 2017 ... The old way was to draw in XOR mode so you didn't destroy the image underneath the “live” object such as a line being dragged by the mouse. The ... Nov 20, 2001 ... The ^ XOR symbol performs a numeric XOR of two numbers (but not a logical one). Thus 1 ^ 2 == 3 Whereas a logical XOR(a,b) would return zero if either both or ... In this way, we can use the XOR operation to solve this problem in O ( N ) O(N) O(N) time and constant space.

I have two arrays of booleans, both have the same known size. I would like to perform a XOR on the arrays and store the result in a third boolean array c. XOR'd Code would typically be included here within a CDATA section.
