To make it possible for algorithmic templates to work directly with input/output streams, appropriate iterator-like class templates are provided.

[Example 1:

partial_sum(istream_iterator<double, char>(cin), istream_iterator<double, char>(), ostream_iterator<double, char>(cout, "\n")); reads a file containing floating-point numbers fromcin, and prints the partial sums ontocout.
