Overload dereference operator

Question

I\'m trying to overload the dereference operator, but compiling the following code results in the error \'initializing\' : cannot convert from \'X\' to \'int\':

Answer 1

You should apply dereference operator to a class type. In your code x has a pointer type. Write the following:

int t = **x;

or

int t = x->operator*();

Answer 2

You're dereferencing a pointer to X. Your class is OK (as far as it's implemented).

int main()
{
    X x; // no pointer
    int t = *x; // x acts like a pointer
}

Answer 3

If you want the original code to work, you need to overload the int-cast operator for your class:

operator int() const { return 5; }
