  • Q3. Runtime polymorphism and how it works vptr and vtable
  • Ans. 

    Runtime polymorphism in C++ is achieved through virtual functions, vptr (virtual pointer), and vtable (virtual table).

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

    • Virtual functions are declared in a base class and overridden in derived classes to achieve polymorphism.

    • vptr is a pointer that points to the vtable of an object, allowing dynamic binding of virtual ...

  • Q2. What is dynamic_cast where it can fail and what will happen in that case
  • Ans. 

    dynamic_cast is a C++ operator used for safe downcasting of pointers and references in polymorphic classes.

    • dynamic_cast is used to safely downcast a pointer or reference from a base class to a derived class.

    • It can fail if the object being casted is not of the target type, in which case it returns a null pointer for pointers or throws a std::bad_cast exception for references.

    • Dynamic_cast can only be used with pointers o...

  • Q2. What is union in c++
  • Ans. 

    Union in C++ is a data structure that allows storing different data types in the same memory location.

    • Unions are similar to structures but all members share the same memory location.

    • Only one member of a union can be accessed at a time.

    • Unions are useful when you need to store different data types in the same memory space.

    • Example: union MyUnion { int i; float f; };

    • Example: MyUnion u; u.i = 10; // Accessing integer member

  • Answered by AI
  • Q3. What is weak pointer
  • Ans. 

    Weak pointer is a type of smart pointer in C++ that does not control the lifetime of the object it points to.

    • Weak pointers are used to break circular references in shared pointers.

    • They do not increase the reference count of the object.

    • They are used in scenarios where the object may be deleted while there are still weak pointers pointing to it.

  • Q4. What are processes and threads memory is allocated to what process or threads? what is mutex and semaphore how many threads/process can you launch at a time what is meaning of core in 4-core system what is...
  • Ans. 

    Processes and threads are units of execution in a computer system. Memory is allocated to processes. Mutex and semaphore are synchronization mechanisms. Core refers to a processing unit in a multi-core system. Context switching is the process of switching between different processes or threads.

    • Processes are independent units of execution with their own memory space and resources.

    • Threads are lightweight units of executi...
