我在下面的代码中通过g ++编译器得到了一些令人讨厌的分段错误.关于为什么会发生这种情况以及如何解决这个问题的任何想法都会很棒.

#include <iostream>
using namespace std;

class Base {
public:
  Base() {}
  virtual ~Base() {};
  virtual int getNum(int) = 0;
};

class Derived: public Base {
public:
  Derived() :
    Base() {}
  ~Derived() {}

  int getNum(int num) {
    return num;
  }
};

class Foo {
public:
  Foo() {
  };
  void init() {
    Derived n;
    *baseId = n;
  }
  void otherStuff() {
    cout << "The num is" << baseId->getNum(14) << baseId->getNum(15) << baseId->getNum(16) << baseId->getNum(15) << endl;
  }
  Derived* baseId;
}; …
