The bitwise shift operators are the right-shift operator (>>), which moves the bits of shift_expression to the right, and … Integers are stored, in memory, as a series of bits. For example, the number 6 stored as a 32-bit intwould be: Shifting this bit pattern to the left one position (6 << 1) would result in the number 12: As you can see, the digits have shifted to the left by one position, and the last digit on the right is filled with a zero. … See more A logical right shift is the converse to the left shift. Rather than moving bits to the left, they simply move to the right. For example, shifting the number 12: to the right by one position … See more

"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 nth bit of number into the variable bit. Changing the nth bit to x. Setting the nth bit to either 1 or 0 can be achieved with the following on a 2's complement C++ implementation: number ^= (-x ^ number) & (1UL << n); " - Bit shift c++
