1 StaticArray设计要点

类模板

封装原生数组
使用模板参数决定数组大小
实现函数返回数组长度
拷贝构造和赋值操作

2 继承关系图和接口实现

继承关系图

接口实现

template < typename T, int N >
class StaticArray : public Array<T>
{protected:T m_space[N];public:StaticArray();// 拷贝和赋值操作StaticArray(const StaticArray<T, N>& obj);StaticArray<T, N>& operator= (const StaticArray<T, N>& obj);int length() const;
};

3 代码实现

StaticArray.h

#ifndef STATICARRAY_H
#define STATICARRAY_H#include "Array.h"namespace LemonLib {template < typename T, int N >
class StaticArray : public Array<T>
{protected:T m_space[N];public:StaticArray(){this->m_array = m_space;}// 拷贝和赋值操作StaticArray(const StaticArray<T, N>& obj){this->m_array = m_space;for (int i=0; i<N; i++){m_space[i] = obj.m_space[i];}}StaticArray<T, N>& operator= (const StaticArray<T, N>& obj){if (this != &obj){for (int i=0; i<N; i++){m_space[i] = obj.m_space[i];}}return *this;}int length() const{return N;}
};
}#endif // STATICARRAY_H

main.cpp

#include <iostream>
#include "Object.h"
#include "Exception.h"
#include "List.h"
#include "Seqlist.h"
#include "Staticlist.h"
#include "Dynamiclist.h"
#include "Staticarray.h"using namespace std;
using namespace LemonLib;int main()
{StaticArray<int, 5> sa;for (int i=0; i<sa.length(); i++){sa[i] = i;}for (int i=0; i<sa.length(); i++){cout << sa[i] << endl;}StaticArray<int, 5> sa1 = sa;for (int i=0; i<sa1.length(); i++){cout << sa1[i] << endl;}StaticArray<int, 5> sa2;sa2 = sa;for (int i=0; i<sa2.length(); i++){cout << sa2[i] << endl;}sa[9] = 0;return 0;
}
