Smart Pointers in C++

Smart pointers are an important feature introduced in C++11 and later versions, used for automatic management of dynamically allocated memory, avoiding memory leaks and dangling pointer issues. Smart pointers utilize RAII (Resource Acquisition Is Initialization) technique to automatically release the managed resources when the object’s lifecycle ends. Below is a detailed introduction to smart pointers … Read more
