Please help with this C++ question:

Consider the following (incomplete) class definition: #include #include using namespace std: class ClassA { private: string *ptr;//pointer to a dynamic array of strings: int size: public: ClassA(int n) { ptr = new string[n]: size = n: } ClassA(const ClassA & other): ~ClassA(): ClassA operator = (const ClassA &rhs): Write an implementation of the assignment operator (outside class specification)
