Memory representation of signed char in c

(2)Memory representation of: signed char a=-7;

Binary equivalent of data 7 in eight bit:  00000111
Binary equivalent of data -7 will be its 2’s complement:
1’s complements of 0000 0111 is 1111 1000
2’s complement will be:




Binary equivalent of data -7 in eight bit:  1111 1001
Data bit: 1111001 (Take first seven bit form right side)
Sign bit: 1       (Take leftmost one bit)

In memory
