发帖数: 61 | 1 I have one class. in order to make my application only have one instance of
this class,
I define a static count, when contructor is called the counter will ++.
my question is when counter >1, how class will destroy itself, when second
instance is trying to create.
Can I call destructor from constructor
except static variable, do we have other way to keep only one copy in my
application?
Thanks so much. | y*******g

I don't think you can call dtr from ctr.
before ctr finishes, the object does not exist, yet.
