An operation that moves all binary digits a specified number of positions either right or left.
A Logic Shift simply moves a set of bits right or left.
A left shift pushes in a zero into the least significant bit position. For an unsigned integer, this is equivalent to a multiplication by 2.

A right shift pushes in a zero into the most significant bit position. For an unsigned integer, this is equivalent to a division by 2.

In C and C++ the logical shift operators << and >> are used as follows:
