Arrange queens on chess board

So I have to arrange 8 queens on a chess board so they can't kill each other. I've been working on this for a while and need some help. I started out by using a 2d array. I placed a 1, (a queen), randomly on the first row. I am trying to base the rest of the queens off of that position by going row by row and placing them in spots where the above and diagonal elements do not add to 1.

    #include<stdlib.h>
    #include<stdio.h>

    #define dim 8


    int main(void)
    {
        int chess[dim] [dim] = {{0, 0, 0, 0, 0, 0, 0, 0},
                        {0, 0, 0, 0, 0, 0, 0, 0},
                        {0, 0, 0, 0, 0, 0, 0, 0},
                        {0, 0, 0, 0, 0, 0, 0, 0},
                        {0, 0, 0, 0, 0, 0, 0, 0},
                        {0, 0, 0, 0, 0, 0, 0, 0},
                        {0, 0, 0, 0, 0, 0, 0, 0},
                        {0, 0, 0, 0, 0, 0, 0, 0}}, i, j, *piece, vert_sum, diag_sum;

piece = &chess[0] [(rand() %8) + 1];
*piece = 1;

vert_sum = vert_sum + chess[i--] [j];
diag_sum = diag_sum + chess[i--] [j--];

for(i=1; i<8; i++)
{
    piece = &chess[i] [j=0];
    while(vert_sum == 1 || diag_sum == 1)
        {
            j++;

        }
    if(vert_sum != 1 && diag_sum != 1)
        {   

            *piece = 1;
        }
}

for(i=0; i<8; i++)
{
    for(j=0; j<8; j++)
    {
        printf("%d ", chess[i] [j]);
        if(j==7)
        {
            printf("\n");
        }
    }
}

}

pretty much everything from vert_sum = vert_sum +.... to if(vert_sum != 1 && diag_sum != 1){*piece = 1;} is random crap I've been trying out. Any help on what I cold do would be greatly appreciated.
