In this video, I explain how to use the type conversion operator to perform conversions between different user defined types.

Explains why initialization should be preferred over assignment. Also explains the concept of member initializer list.

In this lecture, I'll explain why we need smart pointers.

You'll learn about the unique_ptr and its properties in this video.

In this lesson, I'll build an example that will be used to explain why we std::unique_ptr cannot be used in all cases.

I'll try to share the pointer resource using unique_ptr and find out if it works.

Since unique_ptr cannot be used for sharing the underlying resource, I'll replace it with shared_ptr. A shared_ptr allows sharing of the underlying resource and it manages this information through a reference count. Learn how it works in this lecture.

We'll look at a problem with shared_ptr while using a resource that may be destroyed anytime.

Continuing from the previous lecture, you'll learn how weak_ptr can be used to weakly point to a resource without preventing it from getting destroyed. You'll also understand how it achieves this behavior.

In this lecture, we'll learn about circular references and how using shared_ptr may lead to memory leaks. Finally, we'll use weak_ptr to prevent memory leaks.

We can store any kind of resource in a smart pointer, but it needs to be released correctly. This can be done through a deleter. This lesson explains the concept and its usage.

This lesson explains how we can use smart pointers to manage pointers to dynamic arrays.

The construction process of a smart pointer can be simplified with std::make_ functions. You'll learn about these functions in this lesson.
