类的创建、继承、虚函数的使用

原书第23～40页



可以将断点设置在return 0处，然后按F5，

并记录下所有整型数组类ia指针的值，比如：

0x00491f90

0x00491f50

0x00490120

0x00491da0

0x00491d50

然后当调试指针停在return 0处时单步执行，

跟踪每一次析构函数，可以发现后创建的对象最先被消除。



当ia2使用了越界下标时，可以发现执行其析构函数时将报错。

如果ia2也使用越界下标，则会弹出assert信息从而中止。-third edition of the training and guidance of the founders category, inheritance, The use of virtual function bugzhao@sohu.com original paragraph 23 ~ 40 breakpoint can be set up in r eturn 0, then press F5, and record all types of cosmetic ia array of indicators, for instance : 0x00491f90 0x00491f50 0x00490120 0x00491da0 0x00491d50 then stopped when debugging targets in return 0 when the single-step implementation, Tracking every destructor method can be found to create the object first be eliminated.
