这里是vector的一些简单使用：下面直接上代码：

#include <iostream>#include <vector>int main(int argc, char* argv[]){using namespace std;std::cout<<endl;std::cout<<"vector 增删查找一些简单使用："<<endl;std::cout<<endl;std::vector<int> vect;for (int i = 0; i <= 10; i++){vect.push_back(i);}for (int i = 0; i < vect.size(); i++){std::cout<<vect[i]<<",";}std::cout<<endl;for (vector<int>::iterator v = vect.begin();v != vect.end(); v++){std::cout<<*v<<",";}std::cout<<endl;//vect插入数据vect.insert(vect.begin() + 2,3,20);//往vector中第二个位置添加3个数值为20for (vector<int>::iterator v = vect.begin();v != vect.end(); v++){std::cout<<*v<<",";}std::cout<<endl;//往vector的第1个位置插入vector中位置为2到5的数据vect.insert(vect.begin()+1,vect.begin()+2,vect.begin() + 6);for (vector<int>::iterator v = vect.begin();v != vect.end(); v++){std::cout<<*v<<",";}std::cout<<endl;//注释的这部分采用了move方法，会导致vect为空，来自：http://msdn.microsoft.com/zh-cn/library/s5bta5ha(v=vs.120).aspx/*vector< vector <int> > vv1;vv1.insert(vv1.begin(),move(vect));std::cout<<"vv1 size :"<<vv1.size()<<endl;std::cout<<"vv1[0] size :"<<vv1[0].size()<<endl;if ( vv1.size( ) != 0 && vv1[0].size( ) != 0 ){vector < vector <int> >::iterator Iter;cout << "vv1[0] =";for (vector<int>::iterator Iter = vv1[0].begin( ); Iter != vv1[0].end( ); Iter++ )cout << " " << *Iter;cout << endl;}std::cout<<endl;*///vect删除数据vect.erase(vect.begin()+1);for (vector<int>::iterator v = vect.begin();v != vect.end(); v++){std::cout<<*v<<",";}std::cout<<endl;vect.erase(vect.begin()+6,vect.end() -2);//删除这一范围的数for (vector<int>::iterator v = vect.begin();v != vect.end(); v++){std::cout<<*v<<",";}std::cout<<endl;//查找,find是stl里通用的函数,返回所查找数据的迭代器。如果存在多个这样的数据，只返回第一个vector<int>::iterator has = find(vect.begin(),vect.end(),20);if (has == vect.end()){std::cout<<"can't find  number like this";}else{std::cout<<"find first at "<<has - vect.begin()<<" location ";}std::cout<<endl;system("pause");return 0;}

输出（凑合看吧）:
