I am using Visual Studio 2003 to compile and run following program.
There are 4 assignment operation where I expect 2 of them to run ok and 2 of them to raise exception. There is a dynamic casting inside overloaded = operator which expect to fail during non proper cross casting (Casting from Apple to Orange or Orange to Apple). But in my case all the 4 operations are failing ( Raising exception ). I have run the same code in Visual Studio 2008 and it is working fine as expected. But moving entire project to Visual Studio 2008 is difficult. Is this a problem of Visual Studio 2003? If so, is there any way to fix this?
Note: class Fruit is read only and cannot be changed.
class Fruit
{
public:
virtual void operator = ( const Fruit& fruit )
{
}
};
class Apple : public Fruit
{
public:
virtual void operator = ( const Fruit& fruit )
{
Apple& apple = dynamic_cast<Apple&>( fruit );
}
};
class Mango : public Fruit
{
public:
virtual void operator = ( const Fruit& fruit )
{
Mango& mango = dynamic_cast<Mango&>( fruit );
}
};
int main( void )
{
Apple apple;
Mango mango;
Fruit* fruit[] = { &apple, &mango };
*fruit[0] = *fruit[0]; /* Expect to work ok */
*fruit[0] = *fruit[1]; /* Expect an exception */
*fruit[1] = *fruit[0]; /* Expect an exception */
*fruit[1] = *fruit[1]; /* Expect to work ok */
}
