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;
}
