The Need For Smart Pointers
Manual memory management requires to explicitly deallocate memory, or it can lead to memory leaks, which are notoriously hard to track. This makes the need for a tool that handles allocation and proper deallocation obvious.
Smart Pointers Introduction
Smart pointers are objects that automate memory management, even for dynamic memory. There are three kinds of smart pointers.
Smart pointers use object-oriented programming to automate memory management. They are essentially class templates, allowing them to handle different data types while utilizing constructors and destructors for allocation and deallocation. When a smart pointer is created, its constructor is called and when it goes out of scope, the destructor handles cleanup.
smart_pointer.h
123456789101112template <typename T> class SmartPointer { public: SmartPointer(T* pointer) : pointer(pointer) {} ~SmartPointer() { delete ptr; } T* Get() { return pointer; } private: T* pointer; };
To use smart pointers, you need to include the <memory> header file.
including_memory.h
1#include <memory>
