Bitwise Shift Operators

Description

Both operands must be of integral type. The integral promotions are performed on both operands. The type of the result is the type of the promoted left operand.

The left shift operator << shifts the first operand to the left and zero fills the result on the right. The right shift operator >> shifts the first operand to the right. If the type of the left operand is an unsigned type, the >> operator zero fills the result on the left. If the type of the left operand is a signed type, copies of the sign bit are shifted into the left bits of the result (sometimes called sign extend).
