C++ Iterator Library - ostream_iterator
Description
It is a special output iterator that write sequentially to an output stream.
Declaration
Following is the declaration for std::ostream_iterator.
C++11
template <class T, class charT = char, class traits = char_traits<charT> > class ostream_iterator;
Parameters
T − It is an element type for the iterator.
charT − It is a first template parameter of the associated basic_istream object.
traits − It is a second template parameter of the associated basic_istream.
Distance − It is the difference between two iterators.
Return value
none
Exceptions
If x somehow throws while applying the unary operator& to it, this function never throws exceptions.
Time complexity
constant for random-access iterators.
Example
The following example shows the usage of std::ostream_iterator.
#include <iostream> #include <iterator> #include <vector> #include <algorithm> int main () { std::vector<int> myvector; for (int i = 10; i > 1; i--) myvector.push_back(i*10); std::ostream_iterator<int> out_it (std::cout,", "); std::copy ( myvector.begin(), myvector.end(), out_it ); return 0; }
Let us compile and run the above program, this will produce the following result −
100, 90, 80, 70, 60, 50, 40, 30, 20,
