abstraction

  Abstract classes go about as articulations of general ideas from which more explicit classes can be determined. You can't make a theoretical class kind of article. In any case, you can utilize spots and references for conceptual class types. You make a theoretical class by announcing at any rate one unadulterated virtual part work. It is a virtual capacity announced utilizing the unadulterated specifier (= 0) language structure. The classes got from the theoretical class should carry out an unadulterated virtual capacity or they are additionally, dynamic classes. Data abstraction Consider the model introduced in virtual undertakings. The class account is intended to give regular usefulness, however type account objects are too basic to be in any way valuable. This implies that a decent record is a decent possibility for a theoretical class: C ++ Duplicate /deriv_AbstractClasses.cpp /arrange: with/ld Class account { public: Record (twofold D);/constructor.
