Shifting is a fundamental operation in computer instructions, a type of bit manipulation. During shifting, the byte, short, and char types will be promoted to int after shifting. Without compiler optimization (which can be unpredictable), the actual shift count for byte, short, char, and int is the remainder of the shift count divided by 32, meaning shifting 33 bits is equivalent to shifting 1 bit. For long, the actual shift count is the remainder of the shift count divided by
