Vertical Assignment of a 2D array

[aquafina]

Hi,

I have a 2D 3X4 matrix a[3][4]={{0,1,1,0},{1,0,1,0},{0,0,1,1}};
Visually,
0110
1010
0011

Is there a way to assign a vertical strip of a 2D array into a 1D array?
Say, I want to assign the content of 2rd column of the above array into a new 1D array. Output should be
1
0
0

int main()
{
        int a[3][4]={{0,1,1,0},{1,0,1,0},{0,0,1,1}};

        int p[3];

        for(int i=0; i<3; i++)
        {
                p[i] = a[][1];
                cout << p[i] << endl;
        }

        return 0;
}

The error I get is:
error: expected primary-expression before â]â token

Thank you.
