"Splet20. nov. 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) {. " - Swap a bit in c

SpletTo perform bit-level operations in C programming, bitwise operators are used. Bitwise AND Operator & The output of bitwise AND is 1 if the corresponding bits of two operands is 1. If either bit of an operand is 0, the result of corresponding bit is evaluated to 0. In C Programming, the bitwise AND operator is denoted by &. Splet11. feb. 2024 · To set a bit, we'll need to use the bitwise OR operator − Example #include using namespace std; int main() { int i = 0, n; // Enter bit to be set: cin >> n; i = (1 << n); // Take OR of i and 1 shifted n positions cout << i; return 0; } Output If you enter 4, This will give the output − 16 because 16 is equivalent to 10000 in binary.
