    • Q1. What is polymorphism?
    • Ans. 

      Polymorphism is the ability of a function or method to behave differently based on the object it is acting upon.

      • Polymorphism allows objects of different classes to be treated as objects of a common superclass.

      • There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).

      • Example: Inheritance allows a child class to override a method from its parent class, exhibiting polymorphic b

    • Q2. How abstraction is implemented?
    • Ans. 

      Abstraction is implemented in software engineering by hiding unnecessary details and exposing only relevant information.

      • Abstraction is achieved through the use of abstract classes and interfaces in object-oriented programming.

      • It allows developers to focus on the essential aspects of a concept without getting bogged down in implementation details.

      • For example, in a car simulation program, the Car class may have abstract ...

    • Q3. What is the difference between abstraction and Interface?
    • Ans. 

      Abstraction is hiding the implementation details while Interface is a contract that defines the methods that a class must implement.

      • Abstraction focuses on hiding the internal implementation details of a class, allowing the user to only see the necessary details.

      • Interface defines a contract that specifies the methods a class must implement, without providing the implementation details.

    • Q1. What is a constructor in C++?
    • Ans. 

      A constructor in C++ is a special member function that is automatically called when an object is created.

      • Constructors have the same name as the class and do not have a return type.

      • They can be used to initialize the object's data members.

      • Default constructors are automatically generated if no constructor is defined.

      • Parameterized constructors can be defined to accept arguments during object creation.

    • Q2. What is copy assignment operator?
    • Ans. 

      Copy assignment operator is a special member function in C++ that allows one object to be assigned the values of another object of the same class.

      • Copy assignment operator is denoted by the = operator.

      • It is used to copy the values of one object into another object of the same class.

      • It is automatically generated by the compiler if not explicitly defined.

      • Example: MyClass obj1; MyClass obj2; obj2 = obj1; // Copy assignment

    • Q3. What is virtualization in C++?
    • Ans. 

      Virtualization in C++ is the process of creating a virtual version of a class or function to allow for polymorphism and dynamic binding.

      • Virtualization in C++ is achieved through the use of virtual functions and inheritance.

      • Virtual functions are declared in a base class and overridden in derived classes to provide different implementations.

      • Virtualization allows for polymorphism, where a pointer to a base class can point...

    • Q4. Implement String class
    • Ans. 

      Implement a custom String class in a programming language.

      • Define a class with necessary properties and methods to manipulate strings.

      • Include methods for concatenation, substring, length, etc.

      • Handle memory allocation and deallocation properly.

      • Example: class MyString { // implementation }

    • Answered by AI
    • Q5. What is smart pointers?
    • Ans. 

      Smart pointers are objects that act like pointers but provide automatic memory management.

      • Smart pointers help prevent memory leaks by automatically deallocating memory when no longer needed.

      • Examples include unique_ptr, shared_ptr, and weak_ptr in C++.

      • They provide better memory safety compared to raw pointers.
