1, polymorphism can be simply summed up as " one interface, multiple methods ", the program at run time to determine the function called ( lag-linked ).2. C + + polymorphism is achieved through virtual functions, virtual functions allow subclasses

Before the C++11 standard, using C + + to write multithreaded programs either requires a third-party API, such as Pthread, or relies on APIs provided by the running platform, which is inconvenient to use. and C++11 provides platform-independent

As a beginner, using the API in C # is a daunting issue.Before using the API, you must know how to use structs, type conversions, Secure/unsafe code, controllable/uncontrolled code, and much more in C #.Everything starts with simplicity, starting

1. What is polymorphicAnother important concept in object-oriented programming is polymorphism. At run time, you can invoke methods in the derived class by pointing to a pointer to the base class. You can put a set of objects in an array, and then
