vector容器类示例

#include <iostream>
#include <vector>
using namespace std;
int main()
{
    int a[] = {2,3,4};
    vector<int> v1;
    vector<int>::iterator iter;
    //插入元素
    v1.insert(v1.begin(),1,1);
    v1.insert(v1.begin(),a,a+3);
    v1.insert(v1.begin()+4,2,5);
    cout<<"data: ";
    for(iter = v1.begin() ; iter != v1.end() ; ++iter)
        cout<<*iter<<" ";
    cout<<endl<<endl;
    //删除元素
    v1.erase(v1.begin(),v1.begin()+2);
    v1.erase(v1.begin()+1);
    cout<<"data: ";
    for(iter = v1.begin() ; iter != v1.end() ; ++iter)
        cout<<*iter<<" ";
    cout<<endl<<endl;
    return 0;
