如何在C中memcpy迭代元素？

typedef struct 
{
   int age;
   int roomNumber;
} Student;

Student student;
student.age = 20;
student.roomNumber = 10;

vector<Student> studentV;
student.push_back(student);
student.push_back(student);
student.push_back(student);

Student student1[3];

int i;

for(vector<Student>::const_iterator iterator = studentV.begin();
    iterator != studentV.end(); ++iterator,++i)
{
   memcpy(&student1[i],iterator,sizeof(Student));
}

它显示memcpy部分的以下消息：

error: cannot convert 'std::vector<Student>::const_iterator {aka __gnu_cxx::__normal_iterator<const Student*,std::vector<Student> >}' to 'const void*' for argument '2' to 'void* memcpy(void*,const void*,size_t)'

有什么问题以及如何解决？迭代器不能像这样复制吗？
