Erasing a container element that contains a pointer to a dynamically allocated object. When we erase the container element containing pointer to a dynamically allocated object then object has to be destroyed by calling destructor, which release all the resources such as memory else they will remain forever with the container. In order to release memory we must delete every container element container pointer, then erase the vector and swap as shown in code below
