Byte shift in c
WebValue of num = 003F after right shift. Right Shift Operator (>>) is a bitwise operator, which perform operation on bits. It is used to shift given number of bytes in the right and inserts 0’s in the left. Binary of 0xFF in (in 4 bytes format) - 0000 0000 1111 1111. WebMay 27, 2024 · We first create a mask that has set bit only at given position using bit wise shift. mask = 1 << position Then to change value of bit to b, we first make it 0 using below operation value & ~mask After changing it 0, we change it to b by doing or of above expression with following (b << p) & mask, i.e., we return ( (n & ~mask) (b << p))
