WebNov 20, 2024 · Any bit Set bit = Toggle which means, 0 ^ 1 = 1 1 ^ 1 = 0. So in order to toggle a bit, performing a bitwise XOR of the number with a reset bit is the best idea. n = n ^ 1 << k OR n ^= 1 << k where k is the bit that is to be cleared. Below is the implementation of the above approach: #include . int setBit (int n, int k) {.
