如何在 C++ 中从指向向量的指针访问向量的内容？

我有一个指向向量的指针。现在，如何通过指针读取向量的内容？

解决方案有很多，我总结了一些：

int main(int nArgs, char ** vArgs)
{
    vector<int> *v = new vector<int>(10);
    v->at(2); //Retrieve using pointer to member
    v->operator[](2); //Retrieve using pointer to operator member
    v->size(); //Retrieve size
    vector<int> &vr = *v; //Create a reference
    vr[2]; //Normal access through reference
    delete &vr; //Delete the reference. You could do the same with
                //a pointer (but not both!)
}
