Expressions

Bitwise Shift Operators

The bitwise shift operators shift the left operand left (\<\<) or right (\>\>) by the number

of bit positions speciﬁed by the right operand.

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).
