I programmed this vector class to support different types and different amount of dimensions. (class T,int D) D is the dimension.

I don't use templates much and I'm running into an error, my constructors aren't working.

Here is my class

```
#include <stdio.h>
#include <stdarg.h>
template <class T,int D>
class Vector
{
public:
Vector();
Vector(...);
Vector(const Vector<T,D>& vec);
~Vector();
const Vector<T,D>& operator=(Vector<T,D>);
Vector<T,D> operator+(Vector<T,D>);
Vector<T,D> operator-(Vector<T,D>);
Vector<T,D> operator*(Vector<T,D>);
Vector<T,D> operator/(Vector<T,D>);
const Vector<T,D>& operator+=(Vector<T,D>);
const Vector<T,D>& operator-=(Vector<T,D>);
const Vector<T,D>& operator*=(Vector<T,D>);
const Vector<T,D>& operator/=(Vector<T,D>);
bool operator==(Vector<T,D>);
//bool operator==(T);
//bool operator> (Vector<T,D>);
//bool operator< (Vector<T,D>);
//bool operator>=(Vector<T,D>);
//bool operator<=(Vector<T,D>);
//bool operator> (T);
//bool operator< (T);
//bool operator>=(T);
//bool operator<=(T);
T& operator[](const int& index);
//operator const T();
private:
//int Length();
T* dim;
};

return dim[index];
return (T*)0;
}
typedef Vector<int,2> Vector2D;
typedef Vector<int,3> Vector3D;
typedef Vector<int,4> Vector4D;
```

And a basic initialization:

`Vector2D v(1,2);`

here are the errors i'm receiving:

```
\main.cpp||In function 'int main(int, char**)':|
\main.cpp|8|error: call of overloaded 'Vector()' is ambiguous|
\vector.h|59|note: candidates are: Vector<T, D>::Vector(...) [with T = int, int D = 2]|

```

Thank you in advanced. Also if you see anything in my code that needs to be fixed feel free to tell me about them.
