WebMay 5, 2024 · The default, because it is a signed quantity, is to use sign extension. The result of right-shifting a negative value is implementation-defined. GCC uses sign extension. To fix this, use the C logical-shift-right operator, which is >>>, or >>>= and explicitly does a logical shift right even if the quantity being shifted is signed. WebApr 13, 2024 · 1. The left-shift and right-shift operators should not be used for negative numbers. The result of is undefined behavior if any of the operands is a negative number. For example results of both 1 >> -1 and 1 << -1 is undefined. 2.
