C++ “OR” operator

Question

can this be done somehow?

if((a || b) == 0) return 1;
return 0;

so its like...if a OR b equals zero, then...but it is not working for me.

Fun with templates:

template 
struct or_t
{
  or_t(const T& a, const T& b) : value1(a), value2(b)
  {
  }

  bool operator==(const T& c)
  {
    return value1 == c || value2 == c;
  }

private:
  const T& value1;
  const T& value2;
};

template 
or_t or(const T& a, const T& b)
{
  return or_t(a, b);
}

In use:

int main(int argc, char** argv)
{
  int a = 7;
  int b = 9;

  if (or(a, b) == 7)
  {
  }

  return 0;
}

It performs the same comparison you would normally do, though, but at your convenience.
