The following iterators are defined inside the class template:Templateclass classname{private: vector::iteratoriter;};The error that appears is as follows:This is because the vector itself is a template, and the type is unknown until its

Because C + + does not have a final keyword like Java, a class that is decorated with the final keyword in Java cannot be inherited, so it can be cumbersome to use C + + to implement classes that cannot be inherited.In the inheritance mechanism,
