The order in which constructors and destructors of a class are called

First, a snippet of code:

1#include <iostream>2 using namespacestd;3 4 classclock{5 Private:6     inth,m,s;7  Public:8Clock (intH=0,intm=0,ints=0){9h=h,m=m,s=s;Tencout<<"Constructor:"<<H<<":"<<M<<":"<<S<<Endl; One     } A~Clock () { -cout<<"destructor:"<<H<<":"<<M<<":"<<S<<Endl; -     } the }; -  - intMain () { -Clock C3 (Ten,0,0); +Clock C4 ( One); -     return 0; + } AClock C1 (8); atClock C2 (9);

The result is:

We can find several points:

1. Set up the global object first, then set up the local object. Same as normal variable establishment order.

2. Destructors are called in reverse order, because local objects are established in the stack.

3. The destruction of the global object is not displayed, it is called at the end of the program and is not displayed naturally.
