virtual returns types

[theexactpoint]

I am having some trouble with virtual classes with multiple possible return types.
for example lets say i have a virtual class "Gun"

using namespace std;
template<class ammoType>
class Gun
{
	public:
		virtual ammoType getAmmo() = 0;
};

class Rifle: public Gun
{                                   // error on this line
        public:
                ammoType getAmmo()  // error on this line 
                {
                     ...
                }
};

with the errors

error: expected class-name before '{' token
error: `ammoType' does not name a type

this is what i've tried so far but the code isn't working for me. So my question is simply what is my problem and how might i fix it? oh and for fun, lets say the ammoType must be able to be anything like a vector or an int or even another rifle. (This is the reason i used templates.)

Gun isn't a class, so you can't derive from it.

Gun is a template. In order to make it a class you need to give it a type for 'ammoType'.

Here, you'd probably want to make Rifle a template also:

template <typename ammoType>
class Rifle : public Gun<ammoType>  // derive from Gun<ammoType>, not Gun
{
//...
  ammoType getAmmo()  // now this is OK
  {
  }
};
