Requirements

Given the declaration of a class template Vector as shown below, implement the bodies of all the member functions. Please also write a main function to test all the facilities of the class Vector.

template <class T>
class Vector {
public:
  Vector();                      // creates an empty vector
  Vector(int size);              // creates a vector for holding 'size' elements
  Vector(const Vector& r);       // the copy ctor
  ~Vector();                     // destructs the vector 
  T& operator[](int index);      // accesses the specified element without bounds checking
  T& at(int index);              // accesses the specified element, throws an exception of
                                 // type 'std::out_of_range' when index <0 or >=m_nSize
  int size() const;              // return the size of the container
  void push_back(const T& x);    // adds an element to the end 
  void clear();                  // clears the contents
  bool empty() const;            // checks whether the container is empty 
private:
  void inflate();                // expand the storage of the container to a new capacity,
                                 // e.g. 2*m_nCapacity
  T *m_pElements;                // pointer to the dynamically allocated storage
  int m_nSize;                   // the number of elements in the container
  int m_nCapacity;               // the total number of elements that can be held in the
                                 // allocated storage
};

Evaluation standard

1. C++ code quality (clean, compact, and reasonable)

2. Comments quality

3. Test coverage

Files to submit

Please prepare a .zip package including all the source files (including the Vector class and various use cases).
