RefPtrIn the above code, we create a RefPtr object with an integer value of 10. We then call the addItem function and pass in a new integer value of 5 that we want to add to the reference counting smart pointer. Package Library: The RefPtr add item function is a part of the Poco C++ Libraries. Poco provides a set of libraries for building high-performance, multi-threaded applications in C++. The RefPtr smart pointer is used to manage memory in C++ programs. It provides automatic memory management and helps avoid memory leaks.myPtr = new int(10); myPtr.addItem(new int(5));
