Hi, I am trying to complete a project in C + + using the OpenCV library and I have a problem with the display of coordinates of points that are stored in a table "pt" knowing that the table is not empty, here or a piece of code is the error:

CvPoint *pt[result->total];

        for(int i=0;i<result->total;i++){
            pt[i] = (CvPoint*)cvGetSeqElem(result, i);
            cvDrawCircle( img, *pt[i] , 4, cvScalarAll(200) );
           CvPoint x;
        printf("%d \n",pt[i]);

## Thanks :)

Since pt[i] is a pointer, it should be printf("%d \n",pt[i]->x); or printf("%d \n",pt[i]->y); if you wish to print the coordinates.
