代碼如下:

#include <iostream> #include <vector> #include <numeric> #include <algorithm> using namespace std;class myPrint { public:void operator()(int val){cout << val << " ";} };void test01() {vector<int>v1;vector<int>v2;for (int i = 0; i < 10; i++){v1.push_back(i);v2.push_back(i + 5);}for_each(v1.begin(), v1.end(), myPrint());cout << endl;for_each(v2.begin(), v2.end(), myPrint());cout << endl;vector<int >v3;v3.resize(min(v1.size(),v2.size()));vector<int>::iterator itEnd = set_intersection(v1.begin(), v1.end(), v2.begin(), v2.end(), v3.begin());for_each(v3.begin(), itEnd, myPrint());cout << endl; }int main() {test01();return 0; }
