Hey all, I was working on a linked list dynamic memory class when I realized something. I don't know how to dynamicly allocate templet objects. Such as this. Say I have a templet class MemoryBlock. Normally I would say

  MemoryBlock<int> block;

right? er, or was it

  MemoryBlock block<int>;

Anyway, what I want to know is this. If I want to dynamically allocate a templet class, where does the type go? would I do this:

  MemoryBlock<int> *var = new MemoryBlock;

  MemoryBlock *var = new MemoryBlock<int>;

  MemoryBlock<int> *var = new MemoryBlock<int>;

???? Any help is greatly appreciated. Thanks ahead of time. Alex Broadwin A-Tronic Software & Design ----- "if you fail in life, you were destined to fail. If you suceed in life, call me."

A templet most certainly won''t work.

I''m sure it will work. When people do what I am doing, they do not make a class for every data type. And I know people do what I am doing. I just need to know the format. If you have anywhere near a decent compiler, this should work.

Maybe you should try a template instead.

Yes, yes. I can''t spell. You aren''t very helpful now are you? Anyone with some _useful_ information?

The last version should work.

Jeez everyone is a comedian...

To dynamically allocate a templated class object you do so pretty much like anything else dynamic:

MemoryBlock&ltint> *var = new MemoryBlock&ltint>

and:

MemoryBlock&ltint> *var = new MemoryBlock&ltint>[10]; // array of 10 integer MemoryBlocks.

Hopefully this helps you out.

BTW In C++ the type list for the class comes after the class name, not the variable.

This is a little part of my header file:

template class anything
//This is Edem Kwami Attiogbe's Linked List Managing Class
class KwamiLink

private:
struct Link
{
anything any;
int id;
Link *next;
};

Link *head,*tail;
bool ListEmpty();

I templated the whole class and made a struct.
