C++ isn't a pure object-oriented language -- not everything is an
object by any means. Nor are all classes subclasses of a single "Object"
superclass, which is what you're making use of above.
But yes, you can write an "id()" function which behaves differently depending
on what is passed to it. Either:
class foo { virtual int id() { return 1; } };
class bar : foo { virtual int id() { return 2; } };
foo f;
bar b;
cout << f.id(); // 1
cout << b.id(); // 2
// So yours would be:
int id2(foo x) { return x.id(); }
or:
int id(int i) { return 1; };
int id(double d) { return 2; };
cout << id(1); // 1
cout << id(1.0); // 2
Cheers,
aj, who isn't sure this is particularly relevant to debian-devel anymore.
