Exception handling helps you create ________ programs.

Analyze the following code:

``` #include using namespace std; void reverse(int list[], const int size, int newList[]) { for (int i = 0; i < size; i++) newList[i] = list[size - 1 - i]; } int main() { int list[] = {1, 2, 3, 4, 5}; int newList[5]; reverse(list, 5, newList); for (int i = 0; i < 5; i++) cout << newList[i] << " "; } A. The program displays 1 2 3 4 5 and then raises an ArrayIndexOutOfBoundsException. B. The program displays 1 2 3 4 6. C. The program displays 5 4 3 2 1. D. The program displays 5 4 3 2 1 and then raises an ArrayIndexOutOfBoundsException. ```

Let R1 and R2 be sets of attributes and R = R1 R2. Let r be a relation on R. Prove that r? ? R1 (r)  ? R2 (r). Generalize this result to decompositions of R into n > 2 schemas.

What will be an ideal response?
