If i write signed int a = -1 , then ` -1` in 2's complement form is 11111111 11111111 11111111 11111111 and then when i use %d to interpret it it prints -1 and %u , it prints 4294967295 and when i write signed int a = 2 , it prints 2 when i use %d and also when i use %u . If 2 would be in two's complement it would be 11111111 11111111 11111111 11111101 , and then it would be a very diffr answer , what i really want to ask is when does 2's complement happen is it depend on - sign or it happens for every integer if type is signed int which must not be the case here.
