C + + cannot explicitly call constructors, and it generates anonymous objects, which is completely different from Java!

Java has super (), but not in C + +. Take a look at this piece of code:

classA { Public: A () {printf ("A () \ n"); } A (intd) {printf ("A (int) \ n"); A (); } //Cannot call constructor like this! Another anonymous object is generated ~a () {printf ("~a \ n"); }     voidDDD () {printf ("ddd \ n"); } };intMainintargcChar*argv[]) {A aaa (9);    AAA.DDD ();    GetChar (); return 0;}

The output is:
A (int)
A ()
~a
Ddd

But if you change it into
A (int d) {printf ("a (int) \ n");}
The output is:
A (int)
Ddd

Fully prove that there is an anonymous object generated and destroyed in the middle! And I don't know if there's an official solution at the moment, but if you want to define the init () function, forget it.

However, you can explicitly call destructors, as a reference:
