How can access structure in c language?

Answer 1

As you can access any other variable.

Plus you can access the fields of the structure, with the dot operator.

Plus there is the arrow operator to access the fields of a structure addressed by a pointer.

Eg:

struct timeb tb1, tb2, *ptb;

tb1= tb2;

ptb= &tb1;

tb2= *ptb;

tb1.time= tb2.time;

tb2.time= (*ptb).time

ptb->millitm= (&tb2)->millitm;
