    const int N=5;
    string a[N]="www","algorithm","racer","text","wait";

    for(size_t i=0;i<N;++i)
        cout<<b[i]<<" ";
    cout<<endl;

    sort(a,a+N);
    for(int i=0;i<N;++i)//使用sort进行数组排序
        cout<<a[i]<<" ";
    cout<<endl;

    sort(b.begin(),b.end());//向量正序排列
    for(const auto& x:b)
        cout<<x<<" ";
    cout<<endl;

    sort(b.rbegin(),b.rend());//向量倒序排列

    for(const auto& x:b)//基于范围的for循环
        cout<<x<<" ";
    cout<<endl;
    system("pause");
    return 0;
