How cast C++ class to intrinsic type

Question

Basic C++ class question:

I have simple code currently that looks like something like this:

typedef int sType;
int array[100];

int test(sType s)
{
  return array[ (int)s ];
}

What I want, is to convert "sType" to a class, such that the "return array[ (int)s ]" line does not need to be changed. e.g. (pseudocode)

class sType
{
  public:
    int castInt()
    {
      return val;
    }
    int val;
}


int array[100];    
int test(sType s)
{
  return array[ (int)s ];
}    

Thanks for any help.

Answer 1

class sType
{
public:
    operator int() const { return val; }

private:
    int val;
};
