c++ vector遍历容器报错问题

Question

#include<iostream>
#include <cstring>
#include <vector>

using namespace std;

typedef vector<int> V1;
using V2 = vector<int>;

int main()
{
    int nums1[] = {1, 2, 3, 4, 5, 6};
    V1 v1(nums1, nums1 + sizeof(nums1) / sizeof(int));

    int nums2[] = {5, 6, 7}; 
    V2 v2(nums2, nums2 + sizeof(nums2) / sizeof(int));

    for (auto i:v1)
    {
        cout<<i<<" ";
    }
    cout<<endl;

    V1::iterator vp1;
    for (vp1 = v1.begin(); vp1 != vp1.end(); vp1++)  //这里的vp1.end()会报错 ‘std::vector<int>::iterator’没有名为‘end’的成员
    {
        cout<<*vp1<<endl;
    }

    cout<<endl;
    //上述的的vp1.end()会报错 ‘std::vector<int>::iterator’没有名为‘end’的成员
}

Answer 1

vp1 != v1.end()吧
