我正在尝试用C++序列化一组结构.这适用于除我的struct中包含的向量之外的所有数据.我可以将数据写入磁盘,然后将所有数据读回内存.唯一的问题是当我尝试访问向量的元素时,我得到了一个分段错误.我的代码如下.任何帮助是极大的赞赏.

程序写入磁盘

int main {
  struct Student one;
  strcpy(one.FullName, "Ernestine Waller");
  strcpy(one.CompleteAddress, "824 Larson Drv, Silver Spring, MD 20910");
  one.Gender = 'F';
  one.LivesInASingleParentHome = true;
  one.grades.push_back(80);
  one.grades.push_back(90);

  ofstream ofs("fifthgrade.ros", ios::binary);
  ofs.write((char *)&one, sizeof(one));
  ofs.close();
}

程序从磁盘读取

 int main {
    struct Student *two = (struct Student *) malloc(sizeof(struct Student));    
    ifstream ifs("fifthgrade.ros", ios::binary);
    //cout << "Size of struct: " << size << endl;
    ifs.read((char *)two, sizeof(struct Student));
    cout << "Student Name: " << two->FullName << endl;
    cout << "First Grade: " << …
