struct human
{
char *first;
char gender[10];
int age;
} man, *p_human;

struct man *p_man;
int main(void)
{
strcpy(man.gender,"Male");
printf("%s\n",man.gender);
printf("%s\n",p_man->gender); <----------
exit(EXIT_SUCCESS);
}

The "p_man" is pointer to structure "man".what am i missing here.

Thanks,

sheer stupidity by me .(My applogy)
declared a structure pointer and never assigned it to anything(should have assigned it to structure).

Anyways,Better late than never : )
