list::sort

Arranges the elements of a list in ascending order or with respect to some other user-specified order.

void sort( ); 
template<class Traits>  
   void sort( 
      Traits _Comp 
   );

Parameters

• _Comp
  The comparison operator used to order successive elements.

Remarks

The first member function puts the elements in ascending order by default.

The member template function orders the elements according to the user-specified comparison operation _Comp of class Traits.

Example

// list_sort.cpp
// compile with: /EHsc
#include <list>
#include <iostream>

int main( )
{
   using namespace std;
   list <int> c1;
   list <int>::iterator c1_Iter;
   
   c1.push_back( 20 );
   c1.push_back( 10 );
   c1.push_back( 30 );

   cout << "Before sorting: c1 =";
   for ( c1_Iter = c1.begin( ); c1_Iter != c1.end( ); c1_Iter++ )
      cout << " " << *c1_Iter;
   cout << endl;

   c1.sort( );
   cout << "After sorting c1 =";
   for ( c1_Iter = c1.begin( ); c1_Iter != c1.end( ); c1_Iter++ )
      cout << " " << *c1_Iter;
   cout << endl;

   c1.sort( greater<int>( ) );
   cout << "After sorting with 'greater than' operation, c1 =";
   for ( c1_Iter = c1.begin( ); c1_Iter != c1.end( ); c1_Iter++ )
      cout << " " << *c1_Iter;
   cout << endl;
}

Before sorting: c1 = 20 10 30
After sorting c1 = 10 20 30
After sorting with 'greater than' operation, c1 = 30 20 10
