In C, true is represented by 1, and false by 0. However, in a comparison, any non-false value is treated is true. The ! operator does boolean inversion, so !0 is 1 and !1 is 0. The ~ operator, however, does bitwise inversion, where every bit in the value is replaced with its inverse. So ~0 is 0xffffffff (-1). ~1 is 0xfffffffe (-2).
