Question
### Question 10 **Task:** Write both the move assignment operator and move constructor member functions for this templated `CS30Vector` class. ```cpp #include <iostream> template <typename T> class CS30Vector { public: // Constructs a vector size num CS30Vector(int num) {/*Implementation not shown*/} CS30Vector() {/*Implementation not shown*/} // your code will go here // additional member functions not shown private: T *arr=nullptr; // used to point to dynamic array int size; // number of elements in array }; void foo (CS30Vector<int> v){/*Implementation not shown*/} int main ( ) { CS30Vector<int> l1{6}; CS30Vector<int> l2; // uses move assignment operator l2 = std::move(l1); // uses move constructor below foo(CS30Vector<int>(3)); return 0; } ``` ### Explanation This code provides a partially implemented template class `CS30Vector`, which represents a simple dynamic array (vector). Two constructors are declared but not implemented: 1. **Parameterized Constructor:** `CS30Vector(int num)` which initializes a vector of size `num`. 2. **Default Constructor:** `CS30Vector()` which serves as a default initializing constructor. ### Private Members - **arr:** A pointer of type `T` (template type), intended to point to a dynamic array. - **size:** An integer to store the number of elements in the array. ### Tasks to Implement You are required to implement: - **Move Assignment Operator:** Responsible for allowing an object to be moved rather than copied, useful to optimize performance when working with temporary objects. - **Move Constructor:** An essential function to transfer resource ownership from one object to another (also optimizing performance), especially for temporary and rvalue objects. ### Usage in `main` - **Move Assignment Operator** is demonstrated by: ```cpp l2 = std::move(l1); ``` This line shows how the resources from `l1` are moved to `l2`. - **Move Constructor** is utilized in: ```cpp foo(CS30Vector<int>(3)); ``` This line implicitly creates a temporary object of `CS30Vector<int>` which is then moved into the function `foo`.
