How can the following code be improved using STL? const char* studentName[4] = {"Sam", "Alex", "Bibo", "Ali"); std::vector<:string> studentName = {"Sam", "Alex", "Bibo", "Ali"); std::list<:string> studentName = {"Sam", "Alex", "Bibo", "Ali"); = std::map<:string int> {{"Sam", 10}, {"Alex", 15}, {"Bibo", 20},{"Ali", 11}}; std::set<:string> studentName = {"Sam", "Alex", "Bibo", "Ali"); = What is true about a shared pointer? When an object deletes a shared_ptr, the reference count decreases. The shared_ptr class uses reference counting internally to track the objects that share the pointer. When the reference count in a shared_ptr is 0, the pointer is deleted. O When an object copies a shared_ptr, the reference count increases. O All are correct Which of the following can be templatized? Class Standalone methods Virtual methods Class' member methods Overloaded methods
