Re: [Dev-C++] C++ question

[Michael C <jd...@ho...>]

O.K. for argument sake I agree with you.
I agree that the catch block is the end of the constructor only when it is
present.

What I would like to know is what happens when you have an initialiser list
of two or more objects that you want to place a try against.

Would you have the following ?

    X () try : a(1), b(2), c(3)
    {
        ...
    }

How would you determine in the catch who threw the exception ?
I guess each object could throw a different kind of exception and there
could be a catch for each kind. But if they all throw the same kind of
exception I guess you would need some sort of identification in that
exception to correlate it to the offending object.

As I am using an older compiler, HPUX 10.20, I cannot play with this myself.
When I move to HPUX 11, I'll be able to try it out.

Have you tried the above ?

I experimented with Dev-C++ and i concluded that the catch block belongs
to the constructor too. The constructor ends at the end of the catch
block. I guess case is closed...

The code:

#include <iostream>

class Exception {};

class Vector
{
int size;
public:
Vector(int s):size(s) {}
};

class X
{
Vector v;
public:
X(int);

};

X::X(int s) try :v(s)
{
std::cout<<"code run!\n";

throw Exception();

}

catch(Exception)
{
 std::cout<<"Exception caught!\n";
 std::cout<<s;
 this;

}



int main()
{
X a(7);
}
