Lesson 26. Understanding Smart Pointers

C++ programmers do not necessarily need to use plain pointer types when managing memory on the heap (or the free store); they can make use of smart pointers.

In this lesson, you learn

What smart pointers are and why you need them

How smart pointers are implemented

Different smart pointer types

Why you should ...
