What are the output(s) for the following ? #include char *f() {char *s=malloc(8); strcpy(s,"goodbye")} main() { char *f(); printf("%c",*f()='A'); }
What does. int *x[](); means ?

typedef struct{ char *; nodeptr next; } * nodeptr ; What does nodeptr stand for?
Differentiate between null and void pointers.
