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. SpletFirst shift the bit in given position to right-end. This can be achieved by the code below. for p’th bit – n & (1 << p)) >> p) for q’th bit – (n & (1 << q)) >> q) 3.
