Simple.

struct test
{
	char	a, b, c;
};

int	main()
{
	struct test *my_array;

	my_array = (struct test *)malloc(50 * sizeof(struct test));

	if (my_array == NULL)
	{
		fprintf(stderr, "Unable to allocate sufficient
memory.\n");
		exit(1);
	}

	/* put your code here */

	free(my_array); /* if necessary--done automatically on exit */

	return 0;
}
