One thing you could do is to have a static array inside your function
and compute its elements as needed. For example, if you function is
called foo:

	void foo(int n) {
		static int f[MAX_N] = { 1, 1 };
		static int computed = 2;
		
		while (computed <= n) {
			f[computed] = f[computed-1] * computed;
			++computed;
		}
		
		...
	}

(This isn't quite your example, but I hope you get the idea.) Since 'f'
and 'computed' are static, they keep their values from one call to
another.
