i.e 2 << -4 nad 3 >> -5
i want the output to be expained

All I can do here is quote the book:
The result of a shift operation is undefined if the second operand is negative, or if the right operand is greater than or equal to the width in bits of the promoted left operand.
Shifting a negative value to the right yields half the absolute value, rounded down. For example, –253 (binary 11111111 00000011) shifted right one bit produces –127 (binary 11111111 10000001). A positive 253 shifts right to produce +126.
