WebAug 16, 2024 · An operand of essentially enum type should not be used in an arithmetic operation because an enum object uses an implementation-defined integer type. An operation involving an enum object may therefore yield a result with an unexpected type. Note that an enumeration constant from an anonymous enum has essentially signed type.

WebOct 21, 2011 · The & operator performs a "bitwise AND", which means each bit of the left-hand-side is ANDed with the corresponding bit on the right-hand-side. So if we wrote out our two operands in binary: uop->flags 1010 1010 (example) FCTRL 0100 0000. In this example, if you perform an "AND" on each pair of bits, you get the result: result 0000 0000. 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) {.
