The solution given by Ahmed needs change it will not give the correct output. if a=10 then ouput will be -12 as per the problem solun, hence output is wrong. (if i am worng please correct me ). Solution will be as follows :

int a=10
(suppose it values is 10);
a = ~a;
printf("%d",-a);
OUTPUT will be 11;

Consider data is in HEX. Right shift the data till ‘0’ is encountered AND increment the count.
The position where ‘0’ is encountered , change it to ‘1’ and all bits to ‘0’ for all the LSB bits shifted
For e.g Data = 0x 07 = 0000 0111Here, 4th bit from the LSB is ‘0’So, 4th bit will become ‘1’And all the LSB bits before this will become ‘0’

#include<stdio.h>

main()

{

int a=4;

a=~a;

a--;

a=~a;

printf("%d",a);

}
