Fill in the three missing functions in this code, so that numbers are printed out in order. Note that you can debug print_numbers independently.
#include <stdio.h>
#include <stdlib.h>
struct node {
int value;
struct node *next;
};
struct node *read_numbers(void){
struct node *first = NULL;
int n;
printf("Enter a series of integers"
" (0 to terminate): ");
for (;;) {
scanf("%d", &n);
if (n == 0)
return first;
first = add_to_list(first, n);
}
}
struct node *reverse(struct node *list){

struct node *add_to_list(struct node *list, n){

void print_numbers(struct node *list){
}
int main(void){
struct node *list=NULL;

list=reverse(list);
printf("output: \n");
print_numbers(list);
}
