Arithmetic left shift ¹: shifting `-1` in two's complement ² representation to left by one as -1 << 1 At binary level (32-bit words) we have: 1 = 0000 0000 0000 0000 0000 0000 0000 0001 -1 = 1111 1111 1111 1111 1111 1111 1111 1111 and by doing 1111 1111 1111 1111 1111 1111 1111 1111 << 1 we get 1111 1111 1111 1111 1111 1111 1111 1110 = -2 in decimal And "%x" specifier would nicely format the hexadecimal representation of the above bit sequence [converts an unsigned integer into hexadecimal representation hhhh. ³]. Every 4 bits comprise one hex digit. So the total hex numbers are 8 as fffffffe or FFFFFFFE (for "%X") _____ ¹ https://en.wikipedia.org/wiki/Arithmetic_shift ² https://en.wikipedia.org/wiki/Two%27s_complement ³ https://en.cppreference.com/w/cpp/io/c/fprintf
