pros and cons of smart pointers

Question

I came to know that smart pointer is used for resource management and supports RAII.

But what are the corner cases in which smart pointer doesn\'t seem smart and things

Answer 1

Here are a few things

• There's no definite entity which destroys the object. Often it is desired to know exactly when and how an object is being destroyed
• Circular dependencies - If they exist you'll have a memory leak. That's usually where weak_ptr come to the rescue.
