    Mustn't or don't have to

    Don't have  to  means  that  it is not  necessary for someone to do something  (absence of obligation).

    You  don't have  ( it's  not necessary ) to  study the whole poem  by heart : the first few lines will  be enough.


    Mustn't  conveys an order, an obligation .

    You mustn't smoke in  a hospital  (it is strictly forbidden).
