 2 #include <limits>
 3 #include <assert.h>
 4 #include <vector>
 5 #include <algorithm>
 6 #include <functional>   // For greater<int>( )

11 
12 int _tmain(int argc, _TCHAR* argv[])
13 {
14     std::vector<int> vRqt;
15     std::vector<int> vRsp;
16     std::vector<int> vAll;
17     //vAll.reserve(100);
18     vRqt.push_back(11);
19     vRqt.push_back(2);
20     vRqt.push_back(3);
21     vRqt.push_back(22);
22     sort(vRqt.begin(),vRqt.end());
23     vRsp.push_back(31);
24     vRsp.push_back(1);
25     vRsp.push_back(4);
26     vRsp.push_back(11);
27     vRsp.push_back(3);
28     sort(vRsp.begin(),vRsp.end());
29     merge(vRqt.begin(),vRqt.end(), vRsp.begin(),vRsp.end(), back_inserter(vAll)); //合并
30     sort(vAll.begin(),vAll.end());//排序
31     vAll.erase( unique( vAll.begin(), vAll.end() ), vAll.end());//擦出
32     copy(vAll.begin(),vAll.end(),ostream_iterator<int>(cout," "));//显示
33     return 0;
34 }

ZC：注意 第29行 back_inserter() 和 第31行 unique() 的使用
