Array Out Of Bounds Allowed?

Hey everyone, How come I can access non-existent array values and not get any errors??? It just prints 0 when the index is out of bounds, as if the value of that index is 0. Please explain. #include <iostream> using namespace std; int arr[] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; int main() { for (int i = 0; i < 10; i++) { cout << arr << endl << endl; // this works as expected } cout << arr[10] << endl // this prints 0 << arr[11] << endl // this prints 0 << arr[22]; // this prints 0 as well. No errors, nothing. return 0; } Using Code::Blocks.
