long question; short answer <templates>

i have 2 class that are templates. i want a vector of one class to
be a composite member of another class. the will be vector<firstclass>

let me explain in code...without templates the classes would look like this...

...by the way....i'm having trouble with the declaration part;

Code:

class A
{
     int notimportant;
};

class B
{
     vector<A> somevectoroftypeA;
};

now with templates....

Code:

template <class T> class A
{
     T notimportant;
};

template <class T> class B
{
     //cannot figure out how to declare this
     vector<A<T>> variablename;   //?????????????
};

please help


[/code]

Try an extra space between the last two '>'

vector<A<T> > variablename;

the compiler tells me i need a template argument list or something like that

i don't even know if i'm anywhere close with this:
vector<A<T> > variablename;

Code:

#include <vector>
using std::vector;

template <class T> class A
{
     T notimportant;
};

template <class T> class B
{
  
     vector<A<T> > variablename;   
};

int main() 
{
	B<int> b;
}

I hope this example helps you:

CFirst.h

Code:

template<typename T>
class CFirst  
{
public:
	CFirst() {};
	virtual ~CFirst() {};

private:
	T m_member;
};

CSecond.h

Code:

#include "First.h"
#include <vector>

template <typename T>
class CSecond  
{
public:
	CSecond(const T& x) : m_member(x) {};
	virtual ~CSecond() {};

private:
	T m_member;
	CFirst<T> m_member2;
	std::vector<CFirst<T> > m_member3;
};

Dummy.cpp

Code:

#include "First.h"
#include "Second.h"

int main(int argc, char* argv[])
{
	CFirst<int> a;
	CSecond<int> b(4);

	return 0;
}
