ostream_iterator::operator=
Assignment operator used to implement the output_iterator expression *i = x for writing to an output stream.
ostream_iterator<Type, CharType, Traits>& operator=(
const Type& _Val
);
Parameters
- _Val
The value of the object of type Type to be inserted into the output stream.
Return Value
The operator inserts _Val into the output stream associated with the object, followed by the delimiter specified in the ostream_iterator constructor (if any), and then returns a reference to the ostream_iterator.
Remarks
The requirements for an output iterator that the ostream_iterator must satisfy require only the expression *ii = t be valid and says nothing about the operator or the operator= on their own. This member operator returns *this.
Example
// ostream_iterator_op_assign.cpp
// compile with: /EHsc
#include <iterator>
#include <vector>
#include <iostream>
int main( )
{
using namespace std;
// ostream_iterator for stream cout
// with new line delimiter
ostream_iterator<int> intOut ( cout , "\n" );
// Standard iterator interface for writing
// elements to the output stream
cout << "Elements written to output stream:" << endl;
*intOut = 10;
intOut++; // No effect on iterator position
*intOut = 20;
*intOut = 30;
}
Elements written to output stream: 10 20 30
