WebIn the C language, you have several ways to create a negative integer: You can assign a negative value to a variable, you can perform math that results in a negative value, or you can manipulate bits to convert a positive value to a negative one. That final operation isn’t as easy as it sounds.

WebThe simple way to understand this is: For positive number we know that number is converted into binary and then stored in the memory. For storing negative numbers: Forget the sign … Most compilers choose to interpret >> on signed numbers to be arithmetic shift. Thus since the number is initially negative (i.e. the MSB bit is 1), after a right shift, that bit is replaced by another 1 to preserve the sign, ergo you end up with -1 as you started.
