I applied via Recruitment Consultant and was interviewed in Jan 2021. There were 4 interview rounds.

Interview Questionnaire 

5 Questions

  • Q1. How virtual functions work? Vpointer and vtable how it works internally?
  • Ans. 

    Virtual functions allow polymorphism in C++. Vtable is a lookup table for virtual functions and vpointer points to it.

    • Virtual functions are used to achieve runtime polymorphism

    • Vtable is a table of function pointers for virtual functions

    • Vpointer points to the vtable of the object

    • When a virtual function is called, the vpointer is used to lookup the correct function in the vtable

    • Vtable is created at compile time and is un

  • Q2. Virtual constructor and virtual destructor?
  • Q3. Move semantics?
  • Q4. What are pure virtual function? Use of pure virtual destructor?
  • Ans. 

    Pure virtual functions are functions with no implementation in base class. Pure virtual destructor is used to ensure proper destruction of derived objects.

    • Pure virtual functions are declared with the syntax virtual void functionName() = 0;

    • Classes with pure virtual functions are called abstract classes and cannot be instantiated.

    • Derived classes must implement pure virtual functions to be instantiated.

    • Pure virtual destru...

  • Q5. Exception handling in constructor and destructor. Can we do it . If yes how? If not why not ?
  • Ans. 

    Yes, we can handle exceptions in constructor and destructor.

    • In constructor, we can use try-catch block to handle exceptions.

    • In destructor, we should avoid throwing exceptions as it can lead to undefined behavior.

    • If an exception is thrown in constructor, the object is not fully constructed and should be destroyed.

    • If an exception is thrown in destructor, it should be caught and handled properly to avoid program terminati
