该章节中运行,发现第一个 delete worker就会报错;xcode 中也会直接提示错误问题:
解决方法是提供虚析构:
class Worker {
public:
virtual ~Employee() {};
}
class Employee: public Worker {
public:
virtual ~Employee() {};
}
这样在释放worker 释放的时候,不仅能找到虚表Worker 中的数据指针,同时把Employee 其他数据指针也能正确释放。

abs->personArray[i] = abs->personArray[i + 1];
}
删最后一个越界了,emmm... 有鸡蛋里面挑骨头的意思
