%% \probsec{....}
%% که قسمت نقطه چین را می توان به صورت خالی رها نمود. با نوشتن این دستور عبارت سوال به طور خودکار نوشته می شود و سپس شماره آن نیز به طور خودکار قرار داده می شود. اگر شما در نقطه چین موردی را بنویسید این مورد به صورت عنوان سوال قرار می گیرد.  یعنی مثلا در کد زیر:
%% \probsec{شبکه}
%% در این صورت مثلا می نویسد: سوال ۱: شبکه و خود سوال از خط بعدی شروع می شود. 

%% برای شماره گذاری محیط یاد شده ابتدا یک counter‌ تعریف می کنیم.
