Question

i have a class shown below:

template <class TValue>
    class ICData
    {
    private :
TValue value;
    public:
inline ICData()
{
};
TValue get_value();
void set_value(TValue data);
    };

    template <class TValue>
    TValue ICData<TValue>::get_value()
    {
return value;
    }

     template <class TValue>
     void ICData<TValue>::set_value(TValue _value)
     {
value=_value;
     }

i know how to make a pointer array by:

    ICData <int> *ICArray[10];
    ICArray[0]=new ICData<int>();
    ICArray[1]=new ICData<int>();

but is there any way to make a pointer array using template ? like below:

            template <class T>// iknow this code is WRONG
    ICData <T> *ICArray[10];
    ICArray[0]=new ICData<int>();
    ICArray[1]=new ICData<float>();

thanks in advance.

If you wanted to store a pointer that could point to either a ICData<int> or a ICData<float> then those types would have to have a common base class and you could use that common base as the type to point to.

As it stands the type ICData<int> and ICData<float> are not related so other than using void * there is no solution to what you want to do that wouldn’t involve some ugly casts.
