Structure data member access

void main()

{

struct employee

{

unsigned id: 8;

unsigned sex:1;

unsigned age:7;

};

struct employee emp1={203,1,23};

clrscr();

printf("%d\t%d\t%d",emp1.id,emp1.sex,emp1.age);

getch();

}

Output: 203 1 23

We can access the data member in same way, how bit data is stored in the memory:

Minimum size of structure which data member in bit is two byte i.e. 16 bit. (This is called word size of microprocessor. Word size depends on microprocessor. Turbo c is based on 8086 microprocessor which word size is two byte.)

Bits are filled in from right to left direction. 8 bit for id, 1 bit for sex and 7 bit for age.
