Interview after being Laid Off || First Interview || EY|| Bengaluru || Senior software engineer

Interview was schedule for 30 mins.

1. Write syntax for dynamic cast in C++. Why it is used?
   A* a = new B();
   B* b = dynamic_cast<A*>(a);
2. Create vector for storing the shared ptr.
   vector<shared_ptr> v1;
   for(int i = 0; i < 10; i++)
   {
   v1.push_back(make_shared());
   }
3. Can we use move pointer in case of singletion class?
   Using move semantics for a singleton could potentially lead to unexpected behavior and violate the principle of having a single, globally accessible instance. Therefore, it's generally best to rely on the intended access methods provided by the singleton class itself rather than moving its instance pointer.
4. Difference between vector and list?
