If I read Ross' problem correctly, all you really need is:

foo()
{
	int *aPtr;
	char *calloc();

	aPtr = (int *) calloc(NUM_OF_INTS_IN_ARRAY, sizeof(int));
	aPtr[10]++;
}

That last line of code will increment the eleventh integer in the
"chunk" of memory (aPtr[0] being the first).  Keep in mind that you
should check for a NULL pointer from calloc meaining there's not
enough memory for your request.
