:mrdocs:

Container‐based version of the <algorithm> `std::partition_copy()` function to partition a container's elements and return them into two iterators: one for which `pred` returns `true`, and one for which `pred` returns `false.`

== Synopsis

Declared in `<absl/algorithm/container.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
template<
    typename C,
    typename OutputIterator1,
    typename OutputIterator2,
    typename Pred>
constexpr
std::pair<OutputIterator1, OutputIterator2>
c_partition_copy(
    C const& c,
    OutputIterator1 out_true,
    OutputIterator2 out_false,
    Pred&& pred);
----

== Return Value

A pair of iterators to the ends of the `out_true` and `out_false` ranges.

== Parameters
