thnx

Do you have any code? Or is this like any other thread you'v made and your just looking for someone to do an assignment for you?

You'll have to make the question clearer, unless I'm just being dim.

[iamuser2007]

for example this is the positive code.

#include <iostream>
using namespace std;

struct E {
  const char* message;
  E(const char* arg) : message(arg) { }
};

void my_terminate() {
  cout << "Call to my_terminate" << endl;
};

struct A {
  A() { cout << "In constructor of A" << endl; }
  ~A() {
    cout << "In destructor of A" << endl;
    throw E("Exception thrown in ~A()");
  }
};

struct B {
  B() { cout << "In constructor of B" << endl; }
  ~B() { cout << "In destructor of B" << endl; }
};

int main() {
  set_terminate(my_terminate);

  try {
    cout << "In try block" << endl;
    A a;
    B b;
    throw("Exception thrown in try block of main()");
  }
  catch (const char* e) {
    cout << "Exception: " << e << endl;
  }
  catch (...) {
    cout << "Some exception caught in main()" << endl;
  }

  cout << "Resume execution of main()" << endl;
}

The following is the output of the above example:

In try block
In constructor of A
In constructor of B
In destructor of B
In destructor of A
Call to my_terminate

now give any negative example
