strncpy and a structure array in C

[ats007spdou]

Hi, I have the below program...

// structure_arrays.c:

#include <stdio.h>
#include <string.h>

struct index
{
	int		page;
	char	*title;
};

int main()
{
	int i = 0;
	struct index *structure_array[10];

	for(; i < 10; i++)
	{
		structure_array[i] -> page = i * 10;
		strncpy(structure_array[i] -> title, (char *)(i * 2), (size_t)2);
	}

	for(i = 0; i < 10; i++)
		printf("%s %d\n", structure_array[i] -> title, structure_array[i] -> page);

	return 0;
}

...and one of the irritating problems that I'm getting is that when I try to execute the program(it compiles without a hitch), it crashes. I narrowed the problem down to the first use of "structure_array", but I'm not sure how to fix it. Thanks in advance.
