C++/List/list assign
Add data by assign
#include <list>
#include <iostream>
using namespace std;
typedef list<int> LISTINT;
int main(void)
{
LISTINT listOne;
LISTINT listAnother;
LISTINT::iterator i;
// Add some data
listOne.push_front (2);
listOne.push_front (1);
listOne.push_back (3);
listAnother.push_front(4);
listAnother.assign(listOne.begin(), listOne.end());
for (i = listAnother.begin(); i != listAnother.end(); ++i)
cout << *i << " ";
cout << endl;
listAnother.assign(4, 1);
for (i = listAnother.begin(); i != listAnother.end(); ++i)
cout << *i << " ";
cout << endl;
listAnother.erase(listAnother.begin());
}
Use list.assign to replace contents of a list with elements of another list
#include <iostream>
using std::cout;
using std::endl;
#include <list> // list class-template definition
#include <algorithm> // copy algorithm
#include <iterator> // ostream_iterator
int main()
{
int array[ 4 ] = { 2, 6, 4, 8 };
std::list< int > values; // create list of ints
std::list< int > otherValues; // create list of ints
std::ostream_iterator< int > output( cout, " " );
// insert items in values
values.push_front( 1 );
values.push_front( 3 );
values.push_back( 4 );
values.push_back( 2 );
cout << "values contains: ";
std::copy( values.begin(), values.end(), output );
otherValues.insert( otherValues.begin(), array, array + 4 );
cout << "\n\notherValues contains: ";
std::copy( otherValues.begin(), otherValues.end(), output );
values.assign( otherValues.begin(), otherValues.end() );
cout << "\n\nvalues contains: ";
std::copy( values.begin(), values.end(), output );
cout << endl;
return 0;
}
/*
values contains: 3 1 4 2
otherValues contains: 2 6 4 8
values contains: 2 6 4 8
