Frequently a question of the programs printing out their own output appears in code interviews. The question does not really test a skill of a programmer, as much as general awareness of tricks to do that. The quine page by Gary Thompson provides many examples of such applications in various languages. In case you were [...]

With that in mind, look at the following program:
———— program 5.2 ————–
#include
#include
struct tag{ /* the structure type */
char lname[20]; [...]
Will the following program execute?void main()
{
void *vptr = (void *) malloc(sizeof(void));
vptr++;
}
How about this one?
void main()
{
char *cptr = 0?2000;
long *lptr = 0?2000;
cptr++;
lptr++;
printf(†%x %xâ€Â, cptr, lptr);
}Will it execute or not?
