Consider the following class fully implemented, following the rule of three and working without any bugs (including handling the safe empty state in all cases).

#include using namespace std class doubleCollection{ double* m nums; // pointer to dynamic array of integers int m size; // size of the dynamic array of integers public doubleCollection (double* nums = nullptr, int size = 0); double& operator(int index); virtual -doubleCollection(); /* your code goes here */
