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 ...

WebOct 2, 2013 · 3265917058<<16 both sides are int, so the operation will be done in int (32-bits). You need 3265917058LL<<16 then the left-side will be a long long and the operation will be done with that width i.e. 64-bits. Note that the result you will get (240) is not portable.
