WebFeb 19, 2005 · Hey, I'm doing a homework problems and am very stuck. This is your basic bitwise operator problem. I have this one working for small values, but when they approach the maximum 2's compliment size, they return the wrong value. /* * fitsBits - return 1 if x can be represented as an * n-bit... WebFeb 4, 2016 · Thus, it must result in a value of 0 to 32 (0 is when all is 0, 32 is when all is 8), which is the number of bit 1 in the variable x. And thus the function is named bitCount. That is how the function works. Final note: knowing this, you could even change m1 with 0x0F (instead of 0xFF) and the result would still be the same.
