Object-oriented languages such as Java provide interfaces to implement interfaces, but C ++ does not. Although C ++ implements interfaces through pure virtual base classes, for example, the C ++ Implementation of COM is implemented through the pure

[Object-Oriented Programming] When I write an article for the first time, there must be hundreds of errors. I just want to learn some ideas about object-oriented programming.It can be of little use to people who share common interests, but it cannot

From zhidao.baidu.com The Params keyword specifies that the parameter method parameter is used when the number of parameters is variable. After the Params keyword in the method declaration, no other parameters are allowed, and only one Params
