Sort object in a list

[Progesco]

I want to write a function to sort object in a list (don't use STL at all), but I don't know how to use loop in this case. Please help me

here you'll find a tutorial on how loops work:

and i suggest to start with an easy algorithm, like bubblesort:

but the list is different from array

Elements can be swapped, given suitable iterators.
