Thread: Vectors and custom classes

I had an inkling the following code wouldn't work before I compiled it but I was vindicated and I don't feel any good.

Code:

class A
{
private:
	int i;
public:
	A(){}
	A(A& a){i = a.get_i();}
	~A(){}
	void set_i(int j){i = j;}
	int get_i(){return i;}
};

int main()
{
	A b;
	vector<A> bb;
	for(int i = 0; i < 10; i++)
		bb.push_back(b);
	bb[0].set_i(3);
	bb[1].set_i(4);
	...
}

Well, the error message I get is the following:

c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include\vector(810): error C2558: class 'A' : no copy constructor available or copy constructor is declared 'explicit'

Aren't vectors supposed to work with all sorts of classes and types?

And how do you make a copy construtor that works with a vector?
