Consider the storage of timestamp for time of the day in a system. the time stamp format needs/uses 5 bits for seconds/2, 6 bits for minutes and 5 bits for hours (stored as hours-minutes-seconds/2 from msb to lsb format). using these values, seconds/2 may take values from 0 to 31, minutes may take values from 0 to 63, and hours may take values from 0 to 31. in all the three cases, the extra unused values will never be actually used/taken. the total number of bits required to store all the three fields = 5+6+5 = 16. declare three structure-types for the timestamp. first uses unsigned char type for each of the three elements (seconds_by_2, minutes and hours), second uses unsigned int type for each of the three. the third type uses unsigned short and with bit fields specified for each element. print the size of each of the three struct types using sizeof operator for your architecture + compiler. explain the difference if any. which one is better, if any and why ?
