There’s another name for this arcane art which we’ll use in this article: reflection. You probably think there’s already far too much black magic in C++. But I want to convince you that we need reflection in the language today, especially compile-time introspection, and that it’s not...

For those with a background in a procedural programming language, this course provides a foundation in C++ syntax and usage, as well as object-oriented programming. With this training, you learn how to use C++ functions and variables, leverage advanced features — including constructors, ...
Pointers and references can’t be marked tile_static, and any implicit constructors/destructors of tile_static variables aren’t called. Typically (but not always) your tile_static variables are arrays, and they are typically proportional to the tile size, for example:...
CUnknownImpl::CUnknownImpl() { m_uRefCount = 0; g_uDllRefCount++; } CUnknownImpl::~CUnknownImpl() { g_uDllRefCount--; } The constructor is called when a new COM object is created, so it increments the server's reference count to keep the server in memory. It also initializes th...
Although the bootcamp tries to be as comprehensive as possible, it still only covers the bare bones of using modern C++.

Beginning with .NET Core 3.0, theSystem.Text.Runetype represents a Unicode scalar value.Runeis not available in .NET Core 2.x or .NET Framework 4.x. TheRuneconstructors validate that the resulting instance is a valid Unicode scalar value, otherwise they throw an exception. The following exam...
If you need to unclutter your view of some regions of code, you can collapse it. Choose the small gray box with the minus sign inside it in the margin of the first line of a function. Or, if you're a keyboard user, place the cursor anywhere in the constructor code and press Ctrl+...
First, let’s write a class for the types of values that we’ll store in our cache: class DataObject { private final String data; private static int objectCounter = 0; // standard constructors/getters public static DataObject get(String data) { objectCounter++; return new DataObject(data...
It's possible to have an empty class like thisclass Test { }, but it isn't useful. Although it looks empty, it—like all C# classes—inherits from the Object that contains it and includes a defaultconstructorin the main program.
