In this tutorial, you will learn “how to create and use a shared pointer in C++”. This tutorial will be specific to shared pointers, so the primary pre-requisite of this tutorial is that you should have basic knowledge about pointers and smart pointers. ...
Shared Pointersare Smart Pointers that are both strong and nullable. Shared pointers inherently include all the benefits of basic Smart Pointers in that they prevent memory leaks, dangling pointers, and pointers to uninitialized memory, but they also provide additional features, such as:...
* resources never get released (for example, a tree with nodes having (shared) pointers to children but also to the parent, in which * case the parent and the children are referencing each other, in a cycle). To fix this issue, a second smart pointer was created: * * weak_ptr: Poin...
