The C standard doesn't mandate any particular way of representing negative signed numbers.
In most implementations that you are likely to encounter, negative signed integers are stored in what is called two's complement. The other major way of storing negative signed numbers is called one's complement.
The two's complement of an N-bit number x is defined as 2^N - x. For example, the two's complement of 8-bit 1 is 2^8 - 1, or 1111 1111. The two's complement of 8-bit 8 is 2^8 - 8, which in binary is 1111 1000. This can also be calculated by flipping the bits of x and adding one. For example:
1 = 0000 0001 ~1 = 1111 1110 ~1 + 1 = 1111 1111 -1 = 1111 1111 21 = 0001 0101 ~21 = 1110 1010 ~21 + 1 = 1110 1011 -21 = 1110 1011 plz mark me as brainleist
