List application

To illustrate the use of those functions, here is an example.

#include <stdio.h>
#include <stdlib.h>
#include "list.h"
	
LINK string_to_list(char []);
void print_list(LINK);
int count_rec(LINK);
	
int main(void)
{
        LINK h;
	
        h = string_to_list("ABC");
        printf("The resulting list is\n");
        print_list(h);
        printf("\nThis list has %d elements.\n", count_rec(h));
        return 0;
}

The output of the program is

The resulting list is
A --> B --> C --> NULL
This list has 3 elements.
