I agree. Letting them do a complex repetitive task would be a good demonstration.

Here's my proposed task; I do this all the time during development.

Given a long structure of some sort, write a print function for it.
The wrapper is easy, something like the following:
    void
    print_long_structure (FILE *fp, long_struct_t *ls)
    {
        fprintf(fp,"long structure name:\n");

        return;
    }
Each element should be printed on a line of its own, indented a little with name and value separated by TAB:
        structure_element_name:      element_value

If you know emacs, then it's an obvious keyboard macro.
If not, then there's some education to be had, 
including rehearsing keyboard macros, 
thinking about initial conditions, 
preparing for the next iteration (forward-line), etc.

Once you get through all that, writing the code for the next, e.g. 30 lines is easy and very satisfying.

I hope this is worthwhile to someone.
