例1、vector

#include <vector>#include <string>#include <iostream>#include <iterator>#include <algorithm>using namespace std;#pragma warning(disable:4786)//vector和其迭代器typedef std::vector<int> INT_VECTOR;typedef std::vector<int>::iterator INT_VEC_ITER;int main(void){ cout<<"vector 部分"<<endl; /////////////////////////////// vector 部分 INT_VECTOR intVec; //插入1-5 intVec.push_back(1); intVec.push_back(2); intVec.push_back(3); intVec.push_back(4); intVec.push_back(5); intVec.push_back(1); intVec.push_back(2); intVec.push_back(3); intVec.push_back(4); intVec.push_back(5); //遍历 INT_VEC_ITER vecIter; for (vecIter=intVec.begin(); vecIter!=intVec.end(); vecIter++) { cout<<*vecIter<<" "; } cout<<endl; //查找4 vecIter = find(intVec.begin(), intVec.end(), 4); if (vecIter == intVec.end()) { cout<<"Can`t find 4 in intVec."<<endl; } else { cout<< "Find: " << *vecIter << " Pos:" <<"vecIter*****"<<endl;//不注解这处编译出错 } //删除 intVec.pop_back(); intVec.pop_back(); for (vecIter=intVec.begin(); vecIter!=intVec.end(); vecIter++) { cout<<*vecIter<<" "; } cout<<endl<<endl; return 0;}

运行结果：

yuan@yuan:~/work/test> ./cpp_vector
vector   部分
1 2 3 4 5 1 2 3 4 5
Find: 4  Pos:vecIter*****
1 2 3 4 5 1 2 3

－－－－－－－－－－－－－－－－－－－－

Pos处不能得到地址的原因是，

vector不是指针，不可能返回地址，返回的是一个拷贝的对象

例2、list
#include <list>#include <string>#include <iostream>#include <iterator>#include <algorithm>using namespace std;#pragma warning(disable:4786)//list和其迭代器typedef std::list<int>                    INT_LIST;typedef std::list<int>::iterator          INT_LIST_ITER;int main(void){ cout<<"list   部分"<<endl;   INT_LIST intList;    //插入  5 4 3 2 1 1 2 3 4 5    for (int i=1; i<6; i++)    {        intList.push_back(i);        intList.push_front(i);    }    //遍历    INT_LIST_ITER listIter;    for (listIter=intList.begin(); listIter!=intList.end(); listIter++)    {        cout<<*listIter<<" ";    }    cout<<endl;    //查找4    listIter = find(intList.begin(), intList.end(), 6);    if (listIter == intList.end())    {        cout<<"Can`t find 6 in intList.";    }    else    {        cout<<"Find: "<<*listIter;    }    cout<<endl;    //删除    intList.pop_back();    intList.pop_front();    for (listIter=intList.begin(); listIter!=intList.end(); listIter++)    {        cout<<*listIter<<" ";    }    cout<<endl<<endl;    return 0;} 
运行结果：
yuan@yuan:~/work/test> ./cpp_list 
list   部分
5 4 3 2 1 1 2 3 4 5 
Can`t find 6 in intList.
4 3 2 1 1 2 3 4
