WebJun 18, 2012 · 5 Answers. What you can do with simple bitwise operations is taking a power-of-two modulo (divisor) of the value (dividend) by AND'ing it with divisor-1. A few examples: unsigned int val = 123; // initial value unsigned int rem; rem = val & 0x3; // remainder after value is divided by 4.

WebMar 4, 2024 · Bitwise operators are special operator set provided by ‘C.’. They are used in bit level programming. These operators are used to manipulate bits of an integer expression. Logical, shift and complement are three types of bitwise operators. Bitwise complement operator is used to reverse the bits of an expression. WebAs of c++20 the bitwise shift operators for signed integers are well defined. The left shift a<>b is equivalent to a/2^b, rounded down (ie. towards negative infinity). So e.g. -1>>10 ...
WebAug 10, 2016 · AFAIK in C++17 11 will be the only valid output for both cases because it enforces left-to-right evaluation of function parameters. Update: this seems to be not true, as the committee decided (as of N4606) to go with indeterminately sequenced parameter evaluation mentioned at the bottom of P0145R2. See [expr.call]/5.
