\n
\n

A. We can\u2019t create its objects<\/p>\n<\/div>\n

\n

B. We can\u2019t create pointers to an abstract class<\/p>\n<\/div>\n

\n

C. It contains at least one pure virtual function<\/p>\n<\/div>\n

\n

D. We can create references to an abstract class<\/p>\n<\/div>\n<\/div>\n

Answer :\u00a0<\/b>B. We can\u2019t create pointers to an abstract class<\/h3>\n<\/div>\n<\/div>\n
\n

Explanation :<\/h2>\n<\/div>\n
\n
\n
    \n
  • Abstract Class is a class which contains atleast one Pure Virtual function.<\/li>\n
  • An abstract class is a class that is designed to be specifically used as a base class.<\/li>\n
  • It is used to provide an Interface for its sub classes.<\/li>\n
  • Classes inheriting an Abstract Class must provide definition to the pure virtual function, otherwise they will also become abstract class.<\/li>\n
  • You declare a pure virtual function by using a\u00a0pure specifier (= 0)<\/b>\u00a0in the declaration of a virtual member function in the class declaration.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n
    \n

    Example<\/h2>\n
    <\/div> 
    class AB {public:  virtual void f() = 0;};<\/code><\/pre> <\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
