Thread: type casting object to int?

hi Guys,

well i have a small issue (i think). i have a class that only contains one variable and i was wondering if i could assign an object of this class, to a variable of the same type as it's only data member by type casting this class. (among other things) i have tried the following but i get compile errors:

Code:

class A
{
private:
  int a;  
};

int main(int argc, char* argv[])
{
  A objA;

  int b;
  b = (int)objA;

  return 0;
}

with reinterpret_cast also doesn't work:

Code:

b = reinterpret_cast<int>(objA);

can it be done?

If you want to allow conversion to int, provide a conversion function, i.e., operator int(). If implicit conversion is undesirable (and it often is undesirable), then provide a named function that returns an int instead of a conversion function.

interesting.
thanks again laserlight (problem solved)
