#include <iostream> #include <list> #include <string> #include <vector> #include <iterator> using namespace std; int main() { //copy list to list list<string> oldList; list<string> newList; oldList.push_back("test1"); oldList.push_back("test2"); oldList.push_back("test3"); copy(oldList.begin(), oldList.end(), back_inserter(newList)); //copy vector to vector vector<string> oldVector; vector<string> newVector; oldVector.push_back("test4"); oldVector.push_back("test5"); oldVector.push_back("test6"); copy(oldVector.begin(), oldVector.end(), back_inserter(newVector)); //copy list to vector list<string> list1; vector<string> vector1; list1.push_back("test7"); list1.push_back("test8"); list1.push_back("test9"); copy(list1.begin(), list1.end(), back_inserter(vector1)); //copy vector to list vector<string> vector2; list<string> list2; vector2.push_back("test10"); vector2.push_back("test11"); vector2.push_back("test12"); copy(vector2.begin(), vector2.end(), back_inserter(list2)); return 0; }
特别注意:
copy(vec.begin()+3, vec.begin()+6, back_inserter(list2));
这样的情况下,仅仅是拷贝了vec[3]、vec[4]、vec[5] 。
vec[6]并没有拷贝!
