list::swap
Exchanges the elements of two lists.
void swap(
list<Type, Allocator>& _Right
);
friend void swap(
list<Type, Allocator>& _Left,
list<Type, Allocator>& _Right
)
Parameters
_Right
The list providing the elements to be swapped, or the list whose elements are to be exchanged with those of the list _Left._Left
A list whose elements are to be exchanged with those of the list _Right.
Example
// list_swap.cpp
// compile with: /EHsc
#include <list>
#include <iostream>
int main( )
{
using namespace std;
list <int> c1, c2, c3;
list <int>::iterator c1_Iter;
c1.push_back( 1 );
c1.push_back( 2 );
c1.push_back( 3 );
c2.push_back( 10 );
c2.push_back( 20 );
c3.push_back( 100 );
cout << "The original list c1 is:";
for ( c1_Iter = c1.begin( ); c1_Iter != c1.end( ); c1_Iter++ )
cout << " " << *c1_Iter;
cout << endl;
c1.swap( c2 );
cout << "After swapping with c2, list c1 is:";
for ( c1_Iter = c1.begin( ); c1_Iter != c1.end( ); c1_Iter++ )
cout << " " << *c1_Iter;
cout << endl;
swap( c1,c3 );
cout << "After swapping with c3, list c1 is:";
for ( c1_Iter = c1.begin( ); c1_Iter != c1.end( ); c1_Iter++ )
cout << " " << *c1_Iter;
cout << endl;
}
The original list c1 is: 1 2 3
After swapping with c2, list c1 is: 10 20
After swapping with c3, list c1 is: 100
