10. 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 <iostream>
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?
