C ++中struct内部的向量

struct node {
  char name_;
  vector<node*> nbs_;
};

node a, b, c;
  a.name_ = \'a\';
  b.name_ = \'b\';
  c.name_ = \'c\';
  a.nbs_.push_back(&b);
  a.nbs_.push_back(&c);

  for (vector<node*>::iterator i = a.nbs_.begin(); i != a.nbs_.begin(); i++) {
    cout << (*i)->name_;
  }

i != a.nbs_.begin();

i != a.nbs_.end();
