Is it possible that accessing an array outside its boundary corrupt its existing elements
MyObject* array[10];
for(int i=0; i<10; i++)
{
array[i] = nullptr;
}
array[1] = new MyObject();
array[8] = new MyObject();
array[15] = new MyObject();
could accessing array[15] result in the corruption of the elements between 0-10?
could accessing
array[15]result in the corruption of the elements between 0-10?
Yes. This is undefined behavior, and the nature of UB is that anything can happen. In particular, it usually doesn't make much sense to reason about what could happen or what is more likely to happen. It can be anything, including the corruption of some array elements that were intact before UB.
