#include <iostream>

using namespace std;

int main()

    std::set<int> one(arry, arry+7);

}

编译：

g++ main.cpp -std=c++0x

系统环境：

os：Ubuntu 12.04.2 LTS

g++: gcc 版本 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5)

开始使用g++ main.cpp直接编译出错，提示不支持c++11特性，编译时加上-std=c++0x

输出:

one array values:
1, 2, 3, 4, 5, 6, 7,
two array values:
0, 5, 6, 7, 8, 9, 11, 12,
diff array values:
1, 2, 3, 4,
diff array values:
0, 8, 9, 11, 12,
