@Dheeraj, Thanks for the link @Anshul Considering double to be alligned as a 4 byte boundary.. structc_tag
c 1 byte padding 1 byte padding 1 byte padding 1 byte double 8 byte int 4 byte whole structure is multiple of 4 so no padding required. structd_tag 8 byte for double 4 byte for int 1 byte for char padding 3 byte last 3 byte padding for structure size to be multiple of 4 Correct me if am wrong....
