What happend: Exception throws in the .ctor()?

1. If an exception was thrown in a type's .ctor(), then the class's destrutor wouldn't be called.

2. If a exception was catched in a try-catch block, all the well-constructed object will be destructed( destrutor method will be called) before enter the catch section:

try

{

CFoo a;

CFoo b;

throw int();

CFoo c;

}

catch(int& i)

{

//----

}

the destrutor of a, b will be called except c.

3. Any created heap objects will be well-deleted before existing the try block even though an exception occurs.
