代写C++ Vector 向量、代做C++程序设计、代写代做C++-代写C/C++编程

Requirements

Given the declaration of a class template Vector below, write the bodies of the functions, and a main() to test all the facilities Vector provides.

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 number of elements that can be held in currently 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 the following items：

1.the source code (including the Vector class, and various test cases for its usage)

2.makefile (for Mac or Linux users) or .exes (for Windows users) or CMakeLists.txt
