std::vector error

Having the following code

struct Point

{

    Point( int i = 0, int j = 0 ): x( i ), y( j ) {}

    int x, y;

};

#define MAX_SIZE 10

int _tmain(int argc, _TCHAR* argv[])

{

    std::vector<Point> v;

    v.reserve( MAX_SIZE );

    for ( int i = 0; i < MAX_SIZE; ++i )

    {

        v.push_back( Point( i, i ) );

    }

    return 0;

}

I get the error

error C2446: ':' : no conversion from 'const
std::_Vector_iterator<_Ty,_Alloc>' to 'int'
        with
        [
            _Ty=Point,
            _Alloc=std::allocator<Point>
        ]
        No user-defined-conversion operator available that can perform this

        with
        [

            _Alloc=std::allocator<Point>
        ]

The error occurs inside <vector> in this place

iterator insert(iterator _Where, const _Ty& _Val)

{ // insert _Val at _Where

size_type _Off = size() == 0 ? 0 : _Where - begin();

_Insert_n(_Where, (size_type)1, _Val);

return (begin() + _Off);

}

What is the matter?
