C Program to Search and Remove Duplicate Elements From Given Array

void main()
{
  int a[50],i,pos,size;
  clrscr();
  printf("\n Enter size of An array: ");
  scanf("%d",&size);
  printf("\n Enter %d elements in to the array: ",size);
  for(i=0;i<=size;i++)
            scanf("%d",&a[i]);
  printf("\n Enter position where to delete: ");
  scanf("%d",&pos);
  i=0;
  while(i!=pos-1)
            i++;
  while(i<=10)
  {
            a[i]=a[i+1];
            i++;
  }
  size--;
  for(i=0;i<=size;i++)
            printf(" %d",a[i]);
  getch();
