deque::assign
Erases elements from a deque and copies a new set of elements to the target deque.
template<class InputIterator>
void assign(
InputIterator _First,
InputIterator _Last
);
void assign(
size_type _Count,
const Type& _Val
);
Parameters
_First
Position of the first element in the range of elements to be copied from the argument deque._Last
Position of the first element beyond the range of elements to be copied from the argument deque._Count
The number of copies of an element being inserted into the deque._Val
The value of the element being inserted into the deque.
Remarks
After erasing any existing elements in the target deque, assign either inserts a specified range of elements from the original deque or from some other deque into the target deque or inserts copies of a new element of a specified value into the target deque.
Example
// deque_assign.cpp
// compile with: /EHsc
#include <deque>
#include <iostream>
int main( )
{
using namespace std;
deque <int> c1, c2;
deque <int>::const_iterator cIter;
c1.push_back( 10 );
c1.push_back( 20 );
c1.push_back( 30 );
c2.push_back( 40 );
c2.push_back( 50 );
c2.push_back( 60 );
cout << "c1 =";
for ( cIter = c1.begin( ); cIter != c1.end( ); cIter++ )
cout << " " << *cIter;
cout << endl;
c1.assign( ++c2.begin( ), c2.end( ) );
cout << "c1 =";
for ( cIter = c1.begin( ); cIter != c1.end( ); cIter++ )
cout << " " << *cIter;
cout << endl;
c1.assign( 7, 4 );
cout << "c1 =";
for ( cIter = c1.begin( ); cIter != c1.end( ); cIter++ )
cout << " " << *cIter;
cout << endl;
}
c1 = 10 20 30 c1 = 50 60 c1 = 4 4 4 4 4 4 4
