back_insert_iterator::operator++
Increments the back_insert_iterator to the next location into which a value may be stored.
back_insert_iterator<Container>& operator++( );
back_insert_iterator<Container> operator++( int );
Return Value
A back_insert_iterator addressing the next location into which a value may be stored.
Remarks
Both preincrementation and postincrementation operators return the same result.
Example
// back_insert_iterator_op_incre.cpp
// compile with: /EHsc
#include <iterator>
#include <vector>
#include <iostream>
int main( )
{
using namespace std;
int i;
vector<int> vec;
for (i = 1 ; i < 3 ; ++i )
{
vec.push_back ( 10 * i );
}
vector <int>::iterator vIter;
cout << "The vector vec is: ( ";
for ( vIter = vec.begin ( ) ; vIter != vec.end ( ); vIter++)
cout << *vIter << " ";
cout << ")." << endl;
back_insert_iterator<vector<int> > backiter ( vec );
*backiter = 30;
backiter++; // Increment to the next element
*backiter = 40;
backiter++;
cout << "After the insertions, the vector vec becomes: ( ";
for ( vIter = vec.begin ( ) ; vIter != vec.end ( ); vIter++)
cout << *vIter << " ";
cout << ")." << endl;
}
The vector vec is: ( 10 20 ).
After the insertions, the vector vec becomes: ( 10 20 30 40 ).
