Answer 1

According to opencv documentation,

Here is how to create a storage for various OpenCV dynamic data structures and fill a dynamically growing sequence :

CvMemStorage* storage = cvCreateMemStorage(0);
CvSeq* seq = cvCreateSeq( CV_32SC2, sizeof(CvSeq), sizeof(CvPoint), storage );
int i;

for( i = 0; i < 10; i++ ){
  CvPoint pt;
  pt.x = rand();
  pt.y = rand();
  cvSeqPush( seq, &pt );
}
