Please help me with the MIL and classes

Code:

#include <iostream>
#include <string>
#include <sstream>
#include <strstream>
using namespace std;

class CStandardAllocator
{
	class CStandardAllocator()
	{
		cout << 16 << endl;
	}

};

template<class T, class alloc>
class CMCVectorImp : public alloc
{
public:
	CMCVectorImp(int sz, int x) : alloc()
	{
		cout << sz * x << endl;
	}


};

template<class Vect, class T, class alloc>
class cBagAsVectorImp : public Data
{
public:
	cBagAsVectorImp(int sz) : Data(sz,1){}
protected:
	Vect Data;
};


template <class T, class alloc>
class cBagAsVector : public cBagAsVectorImp<CMCVectorImp<T,alloc>, T, alloc>
{
public:
	cBagAsVector(int sz) : cBagAsVectorImp<CMCVectorImp<T,alloc>, T, alloc>(sz)
	{
		cout << sz << endl;
	}
};

template <class T>
class cBag : public cBagAsVector<T, CStandardAllocator>
{
public:
	cBag(int sz):cBagAsVector<T, CStandardAllocator>(sz){}
};



int main()
{
	int dBagSize = 4;
	cBag<double> dBag(dBagSize);

	return 0;

}

Two compiler errors, it says it doesn't recognize the Data as a base class.

Please help,
Thanks,
Terrance

>>Two compiler errors, it says it doesn't recognize the Data as a base class.

I might have been struck blind, but I cant see Data defined either!

You have "Vect Data;" as a nested member......but you cant simply use this to inherit from

Also;

Code:

class CStandardAllocator
{
class CStandardAllocator()
{
cout << 16 << endl;
}

};

Assuming you want a constructor....you dont begin the constructor with the class keyword....if you do the compiler thinks it has a nested class...and then spews because the inner class has the same name and doesnt end its declaration with ';'

What are you trying to achieve? We might be able to give you some ideas

Thank you. I mistakenly put the word "class" in front of the constructor.

Sorry, didn't proof read my own code very well

btw, I'm not that lazy. I did this on my school's computer, and wanted it to compile before they closed up.

Thanks.
