WebApr 4, 2024 · A 1-byte unsigned integer has a range of 0 to 255. Compare this to the 1-byte signed integer range of -128 to 127. Both can store 256 different values, but signed integers use half of their range for negative numbers, whereas unsigned integers can store positive numbers that are twice as large. 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. fluency probes 2nd grade
