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

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

Hi,

I have just tried this on the HPUX 10.20 aCC compiler and it does not 
compile. The 'try' breaks it.

Enclosing the try/catch block within braces does compile.

Out of interest which page of Stroustroups book is this on ?

Regards,

Michael

Here is the compiled code for the HPUX...

#include <iostream.h>

class Exception {};

class Vector
{
  int size;

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

class X
{
  Vector v;

public:
  X(int);
};

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

  catch(Exception)
  {
    cout <<"Exception caught!\n";
  }
}

int main()
{
  X x(3);
  return 0;
}
