1.Boost之array

1.Boost:array,头文件内容

2.boost:array使用案例

#include<boost/array.hpp> //boost所属的头文件

#include <iostream>

#include <string>

using namespace std;

//表示使用boost库，当不加此句时，调用的时候要加上boost前缀

using namespace boost;

void main()

{

    array <int, 5> barray = { 1, 2, 3, 4, 5 };

    barray[0] = 10;

    barray.at(4) = 20;

    int *p = barray.data();//存储数组的指针

    cout << "-----循环输出结果---------" << endl;

    for (int i = 0; i < barray.size();i++)

    {

        cout << barray[i] << " " << p[i] << endl;

    }

    array<string, 3> cmd = { "calc", "notepad", "tasklist" };

    cout << "-------size()--------" << endl;

    cout << "size = " << barray.size() << " max_size ="<< barray.max_size() << endl;

    cout << "-------iterator------" << endl;

    array<int, 5>::iterator ibegin = barray.begin();

    array<int, 5>::iterator iend = barray.end();

    for (;ibegin != iend; ibegin++)

    {

        cout << *ibegin << endl;

    }

    cout << "-------==操作--------" << endl;

    array <int, 5> barray2 = { 1, 2, 3, 4, 8 };

    array <int, 5> barray3 = { 1, 2, 3, 4, 8 };

    array <int, 5> barray4 = { 11, 12, 13, 14, 18 };

    //结果是1，表示两者内容相等

    cout << (barray2 == barray3) << endl;

    cout << (barray3 == barray4) << endl;

    cout << "-------at()操作--------" << endl;

    cout << barray2.at(1) << endl;

    cout << "-------[]操作--------" << endl;

    cout << barray2[1] << endl;

    cout << "-------front()操作--------" << endl;

    cout << barray2.front() << endl;

    cout << "-------back()操作--------" << endl;

    cout << barray2.back() << endl;

    cout << "-------swap()操作--------" << endl;

    cin.get();
