vector容器简单例子

#define _CRT_SECURE_NO_WARNINGS
#include<iostream>
#include<vector>
using namespace std;

void printVector(const vector<int> &bmw)
{
    for (vector<int>::const_iterator i= bmw.begin(); i != bmw.end(); ++i)
    {
        cout << *i << " ";
        cout << endl;
    }
}

void test01()
{
    int arr[] = { 2,4,6,3,1,5 };
    vector<int> v(arr, arr + sizeof(arr) / sizeof(int));
    cout << arr + sizeof(arr) / sizeof(int) << endl;

    printVector(v);

    vector<int> v2(10, 6);
    printVector(v2);
}
void test02()
{
    vector<int>v;
    v.push_back(10);
    v.push_back(20);//尾部插入
    v.push_back(30);
    v.push_back(40);

    v.insert(v.begin() + 2, 180);//指定位置插入
    printVector(v);
    v.erase(v.begin());
    printVector(v);//删除迭代器指向的元素

    v.pop_back();//尾部删除
    printVector(v);

    cout << "---------------" << endl;
    v.erase(v.begin(), v.end());//删除所有
    printVector(v);

}


int main()
{
    test01();
    test02();
    system("pause");
