​Spend some time with C++ and it becomes more obvious that ~0 and -1 are the same thing: 0 is an integer, and ~0 is also an integer, with the bits flipped, and -1 is an integer with the same bit pattern as ~0. So if the intent is to have an unsigned int with the same bit pattern as ~0 or -1, the way to write that is ~0U (0U is an unsigned int, and ~ is an also an unsigned int, but with the bits flipped.) [Invariably C++ throws out warnings and/or errors for this type of thing, unlike C.]
