(8 Questions)

  • Q1. Explain Basic of OOP pillers
  • Ans. 

    The four pillars of OOP are encapsulation, inheritance, polymorphism, and abstraction.

    • Encapsulation: Bundling data and methods together in a class to hide implementation details.

    • Inheritance: Creating new classes from existing ones, inheriting their properties and behaviors.

    • Polymorphism: The ability of objects of different classes to respond to the same method call.

    • Abstraction: Simplifying complex systems by breaking th

  • Answered by AI
  • Q2. What's run time polymorphism
  • Ans. 

    Run time polymorphism is the ability of an object to take on multiple forms at runtime.

    • It allows objects of different classes to be treated as if they belong to a single class hierarchy.

    • It is achieved through method overriding and dynamic binding.

    • Example: Animal class with subclasses Dog and Cat. A method speak() is overridden in both subclasses.

    • At runtime, an object of type Animal can refer to either a Dog or a Cat ob

  • Answered by AI
  • Q3. Explain more about abstraction what are access modifiers
  • Ans. 

    Abstraction is the process of hiding implementation details while showing only the necessary information.

    • Abstraction helps in reducing complexity and increasing efficiency.

    • It allows us to focus on what an object does instead of how it does it.

    • For example, a car's driver only needs to know how to drive it, not how the engine works.

    • Access modifiers are keywords in object-oriented programming that determine the accessibil...

  • Ans. 

    Explaining virtual function problem with vtable and vptr

    • Virtual functions allow polymorphism by allowing child classes to override base class functions

    • Vtable is a table of function pointers that maps virtual functions to their implementations

    • Vptr is a pointer to the vtable of an object

    • When a child class object is pointing to a base class object, the vptr points to the base class vtable

    • This can cause issues if the child...

  • Q5. Difference in ordered and unordered map
  • Ans. 

    Ordered map maintains the order of insertion while unordered map does not.

    • Ordered map is implemented as a balanced tree while unordered map is implemented as a hash table.

    • Ordered map has slower insertion and deletion but faster searching compared to unordered map.

    • Unordered map has faster insertion and deletion but slower searching compared to ordered map.

    • Example: std::map vs std::unordered_map in C++.

  • Answered by AI
  • Q6. What's copy constructor why it is needed to pass by reference
  • Ans. 

    Copy constructor creates a new object by copying an existing object.

    • Copy constructor is used to create a new object with the same values as an existing object.

    • It is needed to pass by reference to avoid creating a copy of the object, which can be expensive.

    • Passing by reference allows the new object to share the same memory as the original object.

    • Copy constructor is automatically called when a new object is created from
