2nd PUC Computer Science Inheritance One Mark Questions and Answers<\/h3>\n

Question 1.
\nWhat is inheritance?
\nAnswer:
\nIn object-oriented programming, inheritance is a way to form new classes using classes that have already been defined.<\/p>\n

Question 2.
\nHow to implement inheritance?
\nAnswer:
\nThe inheritance is implemented using the following syntax class derived_classname : access specifier base classname.<\/p>\n

Question 3.
\nWhat is base class?
\nAnswer:
\nA base class is a class from which other classes are derived.<\/p>\n

Question 4.
\nWhat is derived class?
\nAnswer:<\/p>\n

    \n
  • The class that inherits is called derived class.<\/li>\n
  • The inheriting class is called the derived class.<\/li>\n<\/ul>\n

    Question 5.
    \nWhat is public access specifier?
    \nAnswer:
    \nIt means “public parts of base class remain public and protected parts of base class remain protected for derived class”.<\/p>\n

    \nThe one advantage of inheritance is reusability.<\/p>\n

    Question 8.
    \nIs inheritance possible in c?
    \nAnswer:

    \nAnswer:
    \nThe base class is declared as the virtual base class so that only one copy of its members are inherited by the derived class in a hybrid inheritance.<\/p>\n

    Question 18.
    \nWhat is an abstract class?
    \nAnswer:
    \nAbstract class is one that is not used to create objects. An abstract class is designed only to act as a base class.<\/p>\n

    Question 19.
    \nWhen do we need to inherit?
    \nAnswer:
    \nSuppose X is a class exist and we need new class Y having all properties of X and in addition to its own, then we need to inherit X class to derive Y class.<\/p>\n

    Question 20.
    \nWhen is it necessary to use inheritance?
    \nAnswer:
    \nWhen a newly created class need to acquire properties of existing class and with its own properties then it is necessary to use inheritance.<\/p>\n

    Question 21.
    \nWhat is visibility mode?
    \nAnswer:
    \nThe visibility mode in inheritance specify the access mode of base class members to derived class.<\/p>\n

    2nd PUC Computer Science Inheritance Two Mark Questions and Answers<\/h3>\n

    Question 1.
    \nHow to implement inheritance?
    \nAnswer:
    \nThe inheritance is implemented using the following syntax
    \nclass derived_class name : access specifier base class name<\/p>\n

    Question 2.
    \nWhat is the difference between public and private access specifier?
    \nAnswer:
    \nIn public access mode, protected members of base class remain protected in a derived class. In private access mode, protected members of a base class become private members in a derived class. And the private members of a base class cannot be inherited in both the access mode.<\/p>\n

    Question 3.
    \nMention any two advantages of inheritance?
    \nAnswer:<\/p>\n

      \n
    • Reusability- Inheritance helps the code to be reused in many situations.<\/li>\n
    • Saves Time and Effort- Since the main code written can be reused in various situations as needed.<\/li>\n<\/ul>\n

      Question 4.
      \nMention any two types of inheritance.
      \nAnswer:<\/p>\n

        \n
      • Single inheritance: A derived class with only one base class is called single inheritance<\/li>\n
      • Multiple inheritance: A class can inherit properties from more than one class which is known as multiple inheritance.<\/li>\n<\/ul>\n

        Question 5.
        \nWhat is the difference between inheritance and polymorphism?
        \nAnswer:
        \nThe concept of inheritance provides the idea of reusability. This means that we can add additional features to an existing class without modifying it. Polymorphism means that if the same message is sent to different objects, the object’s behavior depends on the nature of the object it self This means that a general class of operations may be accessed in the same manner even though specific action associated with each operation may differ.<\/p>\n

        Question 6.
        \nWhat is single inheritance? Give an example.
        \nAnswer:
        \nSingle inheritance:
        \nA derived class with only one base class is called single inheritance. For example, If A is base class then class B derive from base class A.<\/p>\n

        Question 7.
        \nWhat is multilevel inheritance? Give an example.
        \nAnswer:
        \nA class can be derived from another derived class which is known as multilevel inheritance. For example, The derived class C inherit B class whereas B is derived from class A.<\/p>\n

        Question 8.
        \nWhat is hierarchical inheritance? Give an example.
        \nAnswer:
        \nWhen the properties of one class are inherited by more than one class, it is called hierarchical inheritance. For example, class B, C and D are derived from base class A.<\/p>\n

        \"KSEEB<\/p>\n

        Question 9.
        \nWhat is hybrid inheritance? Give an example.
        \nAnswer:
        \nIt is the combination of hierarchical and multilevel inheritance. For example, The derived class D derive from the classes B and C whereas both the classes B and C are derived from base class A.<\/p>\n

        Question 10.
        \nWhat is multiple inheritance? Give an example.
        \nAnswer:
        \nA class can inherit properties from more than one class which is known as multiple inheritance. For example, the class C derive from base class A and base class B.<\/p>\n

        Question 11.
        \nWhat is virtual base class? Give example.
        \nAnswer:
        \nThe base class is declared as the virtual base class so that only one copy of its members are inherited by the derived class in a hybrid inheritance. For example, the derived class D derive from the classes B and C whereas both the classes B and C are derived from base class A. Then base class A is inherited twice and to avoid two copies of class A to class D, class A is declared virtual base class.<\/p>\n

        Question 12.
        \nWhat is an abstract class?
        \nAnswer:
        \nThe class is not used to create objects are called abstract class. It is used as base class to get derive class only.<\/p>\n

        Question 13.
        \nWhich are the components which cannot be inherited?
        \nAnswer:
        \nA derived class inherits every member of a base class except:<\/p>\n

          \n
        • its constructor and its destructor<\/li>\n
        • its operator=() members<\/li>\n
        • its friends<\/li>\n<\/ul>\n

          Question 17.
          \nHow does inheritance influence the working of constructor?
          \nAnswer:
          \nThe inheritance influence the working of constructor, if base class contains parameterized constructor, then it is compulsory to pass the arguments using derived class. Normally derived class is used to declare objects therefore derived class is used to pass arguments to base class constructor.<\/p>\n

          If both base class and derive class has constructors, then base class constructor is executed first and then derived class constructor is executed i.e., pass the value using derived class to base class constructor and then to derived class constructor. The derived class is responsible to pass arguments to both base class as well as derived class.<\/p>\n

          Question 18.
          \nHow does inheritance influence the working of destructors?
          \nAnswer:<\/p>\n

            \n
          • Constructors, destructors and overloaded assignment operators are not inherited.<\/li>\n
          • C++ requires that a derived-class constructor call its base-class constructor to initialize the base-class data members that are inherited into the derived class.<\/li>\n
          • If the derived-class’s constructor did not invoke the base-class’s constructor explicitly, C++ would attempt to invoke the base class’s default constructor.<\/li>\n
          • When an object of a derived class is built(constructed):<\/li>\n
          • the base-class’s constructor is called immediately to initialize the base-class data members in the derived-class object and then<\/li>\n
          • the derived-class constructor will initialize the additional derived-class data members.<\/li>\n
          • When a derived-class object is destroyed, the destructors are called in the reverse order of the constructors:<\/li>\n
          • First the derived-class destructor is called, then the base-class destructor.<\/li>\n
          • When deriving a class, the base class may be declared as either public, protected, or private.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
