• For example, we consider\u00a0four classes A, B, C, and D.<\/li>\n
• If an object of type D tries to access members of A, ambiguity arises as to which class it should resolve.<\/li>\n
• If it is class D that C inherited or it is class D that B inherited as a result, compiler throws an error.<\/li>\n
• We\u00a0declare that B and C inherit A virtually, to remove this ambiguity.<\/li>\n
• It ensures that an object of type D will contain only set of member variables from A.<\/li>\n<\/ul>\n

  During multiple inheritance Virtual Inheritance is used to remove the ambiguity of base class, when a derived class inherits the same base class via other classes in C++. For example, we consider\u00a0four classes A, B, C, and D. If an object of type D tries to access members of A, ambiguity arises as to which […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"passster_activate_protection":false,"passster_protect_child_pages":"","passster_protection_type":"password","passster_password":"","passster_activate_overwrite_defaults":"","passster_headline":"","passster_instruction":"","passster_placeholder":"","passster_button":"","passster_id":"","passster_activate_misc_settings":"","passster_redirect_url":"","passster_hide":"no","passster_area_shortcode":"","gtb_hide_title":false,"gtb_wrap_title":false,"gtb_class_title":"","gtb_remove_headerfooter":false,"footnotes":""},"categories":[2080],"tags":[18462,2363,18458,18460,18457,18461,16204,18455,18459,18456],"class_list":["post-4810","post","type-post","status-publish","format-standard","hentry","category-cpp","tag-how-virtual-inheritance-works-in-c","tag-virtual-base-class","tag-virtual-function-in-multiple-inheritance-c","tag-virtual-inheritance-c","tag-virtual-inheritance-in-c","tag-what-is-virtual-base-class-in-inheritance","tag-what-is-virtual-inheritance","tag-what-is-virtual-inheritance-in-c","tag-what-is-virtual-inheritance-mcq","tag-when-do-we-make-a-class-virtual-in-c"],"yoast_head":"\n
