WebMar 17, 2024 · On most of the systems, left most bit is 1 for negative numbers. So, I start with 1. If the system used 8 bits for storing an integer, then 1 would be represented as 0000 0001. I then go on left shifting this number and then check whether its positive. Now, when number becomes, 1000 0000, left most bit is 1 and this would be taken as a negative ... WebDec 16, 2010 · In C, C++, and similarly-syntaxed languages, you can determine if the right-most bit in an integer i is 1 or 0 by examining whether i & 1 is nonzero or zero. (Note that that's a single & signifying a bitwise AND operation, not a && signifying logical AND.) For the second-to-the-right bit, you check i & 2; for the third you check i & 4, and so on by … Web19 hours ago · Closed 25 mins ago.
