When this is run, we sometimes get the following puzzling output: Array elements 9 and 10 are out of order. Even more puzzling, sometimes we don’t get this output. Why?

Suppose we want an array to satisfy the condition, ``` a[0] <= a[1] <= a[2] <= ... ``` And suppose this code is written to implement a test of this condition ``` #include using namespace std; int main() { double array[10] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }; // assume the array is filled somehow. for(int i=0; i < 10; i++) if (array[i] > array[i+1]) cout << "Array elements " << i << " and " << i + 1 << " are out of order.\n"; } When this is run, we sometimes get the following puzzling output: Array elements 9 and 10 are out of order. Even more puzzling, sometimes we don’t get this output. Why? ```
