A bump for the move.

Well, as the error indicates, you need to add an operator<() function. Also, it would be helpful to correct your variable names in the operator>() function you have already defined.

Consider this:


...
public static bool
operator>(school s1, school s2)
{
return s1.tot_stu > s2.tot_stu;
}

public static bool
operator<(school s1, school s2)
{
return s1.tot_stu < s2.tot_stu;
}

...



P.S. It seems odd that you declared your class as "school", instead of "Class" or "Course". Probably the latter is a bit confusing.
