WebA bit shift moves each digit in a set of bits left or right. The last bit in the direction of the shift is lost, and a 00 bit is inserted on the other end. WebWith a bit access, a single bit is accessed with read or write permissions within an integer variable. To do this, add a period and an index to the variable identifier that addresses the bit within the variable.
