Bitwise Operators in C/C++ - GeeksforGeeks
WebTo check a bit, shift the number n to the right, then bitwise AND it: bit = (number >> n) & 1U; That will put the value of the n th bit of number into the variable bit. Changing the n th bit to x Setting the n th bit to either 1 or 0 can be achieved with the following on a 2's complement C++ implementation: number ^= (-x ^ number) & (1UL << n); Web#include "base/check.h" #include "base/compiler ... // Returns true iff value is a power of 2. // // TODO(pkasting): When C++20 is available, replace with std::has_single_bit(). template < typename T ...
