Talking about the memory leak A memory leak is a common and troubling problem for a C + + programmer. Many techniques have been developed to deal with this problem, such as Smart Pointer,garbage collection. Smart pointer technology is more mature,

Iterator: Enumerator If you are creating a class that behaves and behaves like a collection, it is convenient to allow users of the class to enumerate the members of the collection using a foreach statement. This is easier to implement in C # 2.0

int a = 12345678 //format sring output Label1.Text = string. Format ("Asdfadsf{0}adsfasdf", a); Label2.Text = "ASDFADSF" +a.tostring () + "ADSFASDF"; Label1.Text = string. Format ("Asdfadsf{0:c}adsfasdf", a);//ASDFADSF￥1,234.00ADSFASDF

First, decoration (decorator) mode The decoration (decorator) mode is also named wrapper (wrapper) mode [GOF95]. Decorative mode extends the functionality of objects transparently to the client, and is an alternative to inheritance relationships.

Writing an application using C++/CX is not the same as writing a normal C + + application. The interoperability between pure C + + code and Windows Runtime (WinRT) is surprisingly expensive. Based on Sridhar Madhugiri video c++/cx Best practice

Virtual inheritance is primarily to prevent the base class from repeating inheritance, containing multiple identical base classes, resulting in ambiguity and inheriting with virtual base class (virtual base Class), which enables the derived object
