Bit mask example c++
WebThe two Bit 0 values are OR ’ed together, the two Bit 1 values get OR’d, and so on, to form a result value. Because of the way OR and bitwise OR work, you can use it create a bit mask to make sure particular bits in the result value are set to 1. Any bit in the mask that is 0 will allow the binary digit in the other value to be unchanged in ... WebFeb 7, 2024 · Unsigned right-shift operator >>> Available in C# 11 and later, the >>> operator shifts its left-hand operand right by the number of bits defined by its right-hand operand. For information about how the right-hand operand defines the shift count, see the Shift count of the shift operators section.. The >>> operator always performs a logical …
