A binder refers to a process in which a program module and code are interrelated. Static linking is a program's match, the connection is implemented in the compile phase, and is also known as an early match.Overloaded functions use static

Class Template:The type parameterized class template used to implement the data required by the class is particularly important in representing such data structures as arrays, tables, graphs, etc.The representations and algorithms of these data

Local Static objects:At some point, it is necessary to make the life cycle of a local variable run through the function call and the time thereafter. You can define a local variable as a static type to obtain such an object. A local static object is

The problem with the project is how to play the video in WinForm. There were several ways of looking at it, the first being to use the Windows Media Player component directly, and the second was to use DirectX to draw directly on a form or control,

Type conversions are not limited to types in a single inheritance chain (derived classes are converted to base classes or base classes to derived classes), and can be converted between completely unrelated types. The key is to provide a transition
