Question

Very simple problem, but can’t seem to solve it. I’m probably just not thinking right. So I’m using C and I need to be able to sort some images I download into two rows. Like this: http://i.imgur.com/lWkEO.png
So my program will, say, download 30 images and it has to sort it into these two rows just like you see in the picture. So I know I have to loop through them but can’t seem to get it.
Can someone please help me out? Like I said I know it’s simple but just can’t seem to get it to work! Thanks so much! 😀

OK, your loop could either be how Ignacio has done it, or you could do something like this:

int i, imageCount, row, col, imagesPerCol;

//...
imagesPerCol = 2;

for(i = 0; i < imageCount; i++) {
  row = i % imagesPerCol;
  col = i / imagesPerCol;

  //... do image placement here using row and col
}
