Unsigned integers use modulo 2n arithmetic.Section 4.7 Paragraph 2 of the standard says "If the destination type was unsigned, the resulting value is the least unsign Ed integer congruent to the source integer (modulo 2n where n was the number of bits used to represent th e unsigned type). " This dictates that-1 are equal to the largest possible unsigned int (modulo 2n). Section 3.9.1 paragraph 4 says
