vector的遍历删除

#include<bits/stdc++.h>
using namespace std;
int main()
{
    vector<int>num;
    for(int i = 0; i < 10; i++)
    {
        num.push_back(i);
    }

    for(vector<int>::iterator it = num.begin(); it != num.end();)
    {
        if(*it % 2 == 0)
        {
            it = num.erase(it);
        }
        else
        {
            it++;
        }
    }

    for (int tmp : num)
    {
        cout << tmp << " ";
    }
    cout << endl;

    return 0;
}
