May 15, 2016 I love the new C++ 11 smart pointers. In many ways, they were a godsent for many folks who hate managing their own memory. In my opinion, it made teaching C++ to newcomers much easier. However, in the two plus years that I've been using them extensively, I've come across multiple cases where
Smart pointers can facilitate intentional programming by expressing, in the type, how the memory of the referent of the pointer will be managed. For example, if a C++ function returns a pointer, there is no way to know whether the caller should delete the memory of the referent when the caller is finished with the information.
Consider the following simple C++ code with normal pointers. Using smart pointers, we can make pointers to work in way that we don't need to explicitly call delete. Smart pointer is a wrapper class over a pointer with operator like * and -> overloaded.
Nov 18, 2012 One big change to modern C++ style that comes with C++11 is that you should never need to manually delete (or free) anymore, thanks to the new classes shared_ptr, unique_ptr and weak_ptr. Note that before C++11, C++ did have one smart pointer class - auto_ptr. This was unsafe and is now deprecated

Oct 3, 2014 What is std::shared_ptr<> ? shared_ptr is a kind of Smart Pointer class provided by c++11, that is smart enough to automatically delete the associated pointer when its not used anywhere. Thus helps us to completely remove the problem of memory leaks and dangling Pointers.
C++ Standard Library Smart Pointers. unique_ptr. Allows exactly one owner of the underlying pointer. Use as the default choice for POCO unless you know for certain that you require a shared_ptr . shared_ptr. Reference-counted smart pointer. weak_ptr. Special-case smart pointer for use in conjunction with shared_ptr .
Nov 7, 2011 For example, Boost provides the following smart pointer implementations: shared_ptr<T> is a pointer to T using a reference count to determine when the object is no longer needed. scoped_ptr<T> is a pointer automatically deleted when it goes out of scope. intrusive_ptr<T> is another reference counting pointer.
Feb 11, 2013 Ooops. Yet another article on smart pointers of C++11. Nowadays I hear a lot of people talking about the new C++ standard which is nothing but C++0x/C++11. I went through some of the language features of C++11 and it's really an amazing work. I'll focus only on the smart pointers section of C++11.
Jul 15, 2017 what is std::unique_ptr ? unique_ptr<> is one of the Smart pointer implementation provided by c++11 to prevent memory leaks. A unique_ptr object wraps around a raw pointer and its responsible for its lifetime. When this object is destructed then in its destructor it deletes the associated raw pointer.
