Suppose we expect the elements of an array to be in order. However, to be safe, we want our program to test the array and issue a warning in case it turns out that that some elements are out of order. The following code is supposed to do that but there is an error. Can you find it and correct it?

double a [10];

--some code to fill the array

for (int index = 0; index < 10; index++)

if (a[index] > a[index + 1])

cout << array elements << index << and << index + 1 << are out of order << endl;
