[Dev-C++] Help

[<jd...@da...>]

C++ Exceptions are not catched!!!!!!!!!!!!!!!

Why?

I had build a Dll who throws some exception but the program who calls dll
methods don't catch exceptions and closes abnormally.
Then I tried this simple exe: don't works at all.
Here the simple exe's code.
There's something wrong?
Please help me. (I use Dev 4.9.3.0)


#include <sys/types.h>
#include <iostream.h>
#include <stdlib.h>
class Vector
{
private:
  size_t si;
  int *value;
public:
  class BadIndex {};
  class BadSize {};
  class BadAllocation {};
  Vector (size_t);
  int& operator[](size_t);
};
Vector::Vector (size_t s)
{
  if (s <= 0) throw BadSize();
  si = s;
  value = new int[si];
  if (value == 0) throw BadAllocation();
}
int& Vector::operator[] (size_t i)
{
  if ((i < 0) || (i >= si)) throw BadIndex();
  return value[i];
}
int main (int, char **)
{
  Vector *v;
  try
  {
    int si, index;
    cout << "Give the size of the array: ";
    cin >> si;
    v = new Vector (si);
    cout << "Give an index in the array: ";
    cin >> index;
    cout << "Give its value: ";
    cin >> (*v)[index];
  }
  catch (Vector::BadSize)
  {
    cerr << "The size of an array must be greater than 0.\n";
    exit(1);
  }
  catch (Vector::BadAllocation)
  {
    cerr << "Memory allocation error.\n";
    exit(2);
  }
  catch (Vector::BadIndex)
  {
    cerr << "Index out of range.\n";
    exit(3);
  }
  //...
  system("pause");
  exit(0);
}
