Dynamic Link and dynamic link library

Dynamic Link is relative to static link. In program design, in order to achieve code and module reuse, the program designer often makes common function functions into a library. When the program needs to implement a function, it directly calls the function in the library file, this achieves code reuse. In early programming, reusable function modules were stored in static library files in the form of compile
