“Virtual” is qualifier or keyword in C++?

Question

“Virtual”是C ++中的限定符或关键字？

Answer 1

virtual is a keyword and a function-specifier . It's not a qualifier. C++ only talks about cv-qualifiers (ie const and volatile ); the only other uses of the word qualifier refer to scope resolution prefixes (ie global :: and ns:: and class_name:: prefixes) in qualified ids.

Answer 2

它既是限定符又是关键字！

Answer 3

'virtual' is a keyword and a qualifier. C++ is case sensitive and won't understand 'Virtual'.
