Can u give me a sample program bout linked list and structure in C?

The text in printf and the variables are in Romanian

Can u give me a sample program bout linked list and structure in C?
For Structure


/* The mechanism of a structure */





/* Define a type "person" to include


- forename and surname


- age and childcount */





typedef struct {


char forename[20];


char surname[20];


float age;


int childcount;


} person;





int main (int argc, int *argv) {





/* Create two persons */


person jimmy, flossie;





float avage;





/* Fill up each of the persons with information */


strcpy(jimmy.forename,"James");


strcpy(jimmy.surname,"Conway");


jimmy.age = 32.0;


jimmy.childcount = 2;





strcpy(flossie.forename,"Florence");


strcpy(flossie.surname,"Conway");


flossie.age = 21.0;


flossie.childcount = 2;





/* Calculate the average age of the persons */


avage = (flossie.age + jimmy.age) / 2.0;





/* Print out the persons names and the average age */


printf ("About %s and %s ...\n",flossie.forename,


jimmy.forename);


printf ("Their average age is %.2f\n",avage);





return 0;





}


/* st1.c








Sample output


[graham@saturday c]$ ./st1


About Florence and James ...


Their average age is 26.50


[graham@saturday c]$
