Hi all,
I need help with template class. Say I have a template
array class with non-type argument:
template<class D, int size=10> class aType {
public:
D *data;
aType(){data = new D[size]}
...
}
What I want to do is use it typedef. If there is no
non-type template argument 'size', just only class D,
I can use typedef aType<int> intarray; But here I
can't use typedef as int can be all integers. Is there
any way to do this? Thanks.
Nyinge

Hi Nyi,
Yes, there is a way to do it.
Don't use typedef. Use another template class. Depending on your needs,
try one of...
template <int size=10> class intarray : public aType<int, size>
{
// yada yada yada
};
...or...
template <int size=10> class intarray
{
private:
aType<int, size> mArray;
// yada yada yada
};
HTH,
