Use of auto_ptr in C++
In my program I am using objects of the class some_object that are contained in containers. These containers are released in the destructors of objects of class some_object. Some_object manages some_object instances using "pointer to" rather than pointers and does the following in its destructor:
delete the_object;
Then, some_object is constructed again and the_object is destructed. If I had a pointer to the_object instead of an object of class some_object, how would I release the the_object?
I think it should be similar to this:
delete *ptr;
If I am wrong, I would be glad if you could tell me.
A:
You need to use a smart pointer. Auto_ptr is the standard C++11 version, and, while it's a bit simpler to use, it's also more prone to leaks. The standard library has a number of alternatives. For example:
boost::scoped_ptr
boost::shared_ptr
std::auto_ptr
std::unique_ptr
std::shared_ptr
A:
You can use any kind of pointer, but you need to delete the pointer somehow.
