Sort down a c struct

Question

How can i sort down this struct only with the int ?

   struct buch {         
   string buchtitel;
   int preis;
   } buch;

You need more explaination about your issue, sorting a lonely struct is not something that makes sense. Maybe you forgot avout a vector or a list of `buch` to be sorted ? — Lohrun, Oct 31 '13 at 09:59

Yet again: are you asking about C or C++? They are different languages, with different libraries offering different ways to sort things. — Mike Seymour, Oct 31 '13 at 10:12
I think by the user accepting my answer, it is obvious that I correctly determined what they were asking. — CashCow, Oct 31 '13 at 12:52

If this is C++11 you can use a lambda function.

std::sort
  ( 
     beginIter, endIter, 
     []( buch const& lhs, buch const& rhs ){ return lhs.preis < rhs.preis; } 
  );

where beginIter and endIter define random-access iterators to the items you wish to sort, endIter being one past the end of the range.
