I have an stl vector array which stores the pointers to objects.
To delete the array i am using:
std::vector<*foo> bar;

delete itr;
itr = NULL;

Shouldnt this be
delete (*itr);
?
I guess you are deleting the objects being referred to by the vector
elements. Maybe I am wrong.
It's really hard to conclude anything (although you're probably right)
since the code presented is not real code. For example, 'vector<*foo>'
is a definite syntax error.
Not to mention the fact that such a loop would loop forever, since itr is
set to NULL on the first iteration,
And that line will probably only compile at all if vector<T>::iterator
happens to be implemented as T*, which is not necessarily the case.
The vector<T>::iterator is a type defined as T* for sure.
Not "for sure" at all. See the other replies.
This is how the iterator is defined in vector:
In one particular library implementation.
