Managing the lifetime of dynamically allocated memory and the objects residing in it is one of the challenges that can be hard to do right. It is usually handled by assigning […]

Modern C++ Features - Move Constructor and Move Assignment

In my last post I gave a little introduction to move semantics and a very brief description of rvalue references. This time I will cover two special functions that are based on those language features and are key to integrating them into each and every C++ program: The move constructor and move assignment operator.

One of the biggest changes in C++11 were the introduction of rvalue references to allow the implementation of move semantics. I will give an overview of the basic idea of move semantics, its related features and how to use them.

Have you ever seen a codebase crawling with `DWORD_PTR`, `HANDLE` and similar types? I bet it was a Windows application which never has been (and probably never will be) ported to another operating System, because it had fallen victim to a leaky or nonexistent encapsulation of WinAPI.

In my last post I have written about braced-or-equal-initializers for class members, a feature that enables simpler constructors through default values for members. Today’s post is about two related features that can simplify the writing of constructors even further.

Don’t get me wrong. Unit tests are your friends when developing a class. But they should not be that class’ `friend`. Here’s why.
