how abstract classes works behind the scenes in memory
Me postulé en línea. El proceso tomó 2 semanas. Acudí a una entrevista en NVIDIA (Moscú, ) en ago 2018
Entrevista
I participated in one on-site interviews at NVidia. Interview were split into 2 parts of 1-hour long sessions with different teams. Be prepared to write your code on white board.
Suppose we have std::vector< std::string > with N strings and no reserved space. We want to add one more element to vector. How to implement push_back() most efficiently?
Suppose we have std::vector< UserType > with N elements and no reserved space. UserType is some complex user type. We want to add one more element to the vector. How to implement push_back() most efficiently?
We need to implement variadic template function that takes arbitrary number of arguments of unknown types and it should return sum of the arguments with type int.
We have pointer to 2D array of size NxM - int** A. We need to get value of element A[3][4], but we can not use ‘[’ and ‘]’. How we can do it if we know that such element exist?
Suppose we have class A that is publicly inherited from classes B and C. Also class A contains member variable of class D. We know that constructor of class B throws exception. If we would create object of class A, in which order constructors and destructors will be called?
